Hi Guys

Am looking for as much info on RS_RA Liberty Turbo engines as possible. I also want to find one and import it back here to AUS. with low k's good condition as a half cut!!!

Hope you guys can help
Cheers
Matt

What kind of info are you looking for? Specs? Identifying features to help make sure you are getting one? What do you mean by tell me everything about them? I can tell you that they are rarer than early WRX STi's...

And just out of cusiousity, why are you set on an RS-RA? They use an old outdated head design. You can get an engine with very similar potential and ease of conversion from a regular 94-96 WRX that has newer redesigned heads. And what car are you going to put this in?

Hi Matt

I own a 1992 RS liberty Aus delivered!!
I am looking for a stock RA or one with WRX heads.
No one here knows much about them so I was trying to find out whether they are rated good or bad.
I know what you mean about heads cause most of us here have tappett noise which is totally rank.
I have thought very hard about putting a WRX engine in. I suppose I dont really want a hybrid car if that makes sense. Do you know how to identify a RS_RA Engine??? Apart from the gold rocket covers??? Is there engine numbers that are a tell-tail sign.

cheers for your help!
mgfe

RS RA's had good heads ( gold valve covers as well ).I remember hearing that older subaru DOHC heads were in demand since they flow quite well or something like that.

Mark,

Mgfe,
Unfortunately, I have never seen a document that listed what applied model code or applied engine code to look for when searching for an RS-RA clip. The gold rocker covers and gold AWIC, along with a VF-12 turbo are the only tell tale signs that I know of to identify the engine.
Like I said they are rare. They made 200 in '89 and 20 a month after that until '92, IIRC. So we are talking about less than a 1000 total ever produced, and they all had the old head design.

Personally, I would just change the heads on your Liberty over to any post-94 WRX heads. They will be way quieter and are able to hold a higher redline of 7500 (that is one advantage of the RS-RA heads over standard Liberty EJ20G heads, but like I said, the WRX heads will do the same.) If you whole engine is tired, then get a complete WRX EJ20 engine. It is a direct replacement for your engine and you wouldn't need to rewire anything. Whatever aftermarket stuff you currently have on your car will bolt right on. Even if you do find an RS-RA engine, only the engine itself, along with it's bigger turbo will be a gain. And on the WRX engine, you could even switch over your coil on plug ignition and use that for spark if you got a newer engine with a central coil-pack...

I am doing a Liberty conversion myself right now on a 1990 USDM Legacy. I don't plan on keeping the car long enough to really supe it up past around 240-250hp. But if I was keeping it, you can bet I would get the better heads and bigger turbo for bigger power.

whats all this noob talk?

:p

i found out now :(

not sure what car you are talking about.

if its the legacy turbo they made about 850. that was from 91 to 94.

if you want info on the ej22T then go to legacycentral.org

Hi Matt

Thanks for that info.
To do the WRX head conversion here costs 4000.00 dolars AUS. Some were replaced here under warranty but a lot were not. So thats not an option. I have thought long and hard about putting a front cut out of WRX. Waht Series and year would you recommend??
I have already changed coil packs over to BOSCHE 716's.. Very nice.
I did find this though

Subiekid,
We are talking about the JDM Legacy RS-RA. The production numbers I was talking about come from that last link that mgfe posted. This is not a discussion about USDM cars or production numbers.;)

mgfe,
I would suggest a '94-96 wrx engine. The primary reason is simplicity. You won't need a whole front clip, but just an engine. The CR is the same as are many other things, like intake plumbing, ignition. You would literally just need to pull out your old engine and put in the new one. You could use the WRX ECU to run it for more a little more power, but it is not totally neccessary. Even you AWIC would swap right over.

After '97, the WRX engine was totally redesigned and doing a swap is way more complicated. Sure these engines were rated for 20-40ps more from the factory, but a boost controller and a few other things on the older engine easily gets you there. The older WRX engines got the TD05 turbo, which is capable of more than 300ps at the crank.Plus, being down under, you have easy access to MRT and all of their tuning parts to make good power.

If you have an engine hoist and a good tool set, you should be able to get the WRX engine put in in a long weekend. I am currently doing a Legacy GT conversion on a 1990 non-turbo, and should have the engine out of the car in the next few hours. I have put in about 5 hours work so far. Mine is going to be a little more difficult because it is a non-turbo car and requires wiring, but I figure that the mechanical side of it is going to run about 20 hours total. And I haven't done anything this major automotively in 4 years, and never on my own without a real mechanic to help me...

Hi
Thanks Matt
You nipped everything in the bud there with your reply. How do the 94-96 series engines stack up to the rest of the line up though???
I have just purchased a VF29 IHI Turbo so I will probably bolt this on at some stage too.


Hust on the RS-RA topic. No one knows anything about them here so it is hard to get educated. I think I may have found one but I dont know its history.


Cheers
mgfe

The '94-96 EJ20's are excellent engines. The primary reason that I suggestes them is because they will truly just drop in to replace your current engine. Like I said, from '97 on you will need to change a ton of stuff like the intake and the ECU. It would not be as simple as just finding a good condition engine. It would require finding a complete swap or front cut. Also, the 94-96's come with the TD05 turbo, which would be a worthy upgrade.

But you have done better with that VF-29. I have one in my garage for a little project I have going. They flow about as many CFM's as the TD05 do, but they spool up way quicker. The TD05 does make a little more power up top, but the VF-29 will still deliver 17psi@7000rpm and was the stock turbo on STI v6 WRX's. That is good enough in my book. And it is a newer bearing design.
The only catch with it is that you will need to get a 90 degree inlet elbow added, or totally customize you intake to accomodate.

Can you get pics of the RS-RA? How about vin#, chassis codes and applied engine codes? Any information you can get on it and post would be great to add to my own personal records that I keep. very few people here know very much about them either. What little I have turned up took many hours of research...

Thanks Matt
I will try to find info out on the RS_RA but it is sooo hard to find out anything.

Have researched for hours too.
Anybody else got anything to add??
Cheers
mgfe

the one note that i have to add is that it is my understandnig that the RS-RA also had hand ported heads ..simmilar to the early ITRs.. remember this is in the pre STI days

hi there
I have emailed many wreckers over in the USA and no-one seems to want to help me locate an RS_RA Engine / front cut.
Does anyone know where I can source one??


Cheers
mgfe

bump

Sorry Matt,
I have been pretty distracted and haven't made any efforts in that direction. Who have you talked to? Then I might be able to make some suggestions of companies you missed...

Matt

Its really hard to keep track when your eons away. I just sat down one nite and searched and emailed everyone that I thought could help.

I got hardly any replies. I think that people cant be bothered with one order from OS.

So I suppose I need a locals knowledge and perspective to help me out.

I have manged to locate one here buts its missing loom ecu etc etc. They didnt even know what it was till I started asking questions bout it. It had no history k's (mileage) , all that so I have stayed away from it. For all I know could have 200k's on it. Way too much.

Again any help would be much appreciated.

Cheers
Matt

How much do they want for it? It might be worth picking up as long as it is in working condition. Rebuilding it and replacing a few wear items like crank bearings wouldn't be too expensive as long as it didn't suffer something like a broken timing belt and valve to piston collision.:eek: And just cracking off the heads to change the head gasket will give you a good idea of internal conditions. I wouldn't worry too much about a missing wiring harness or ECU. You can use your stock stuff on that engine. The key pieces are the engine itself, the bigger injectors and the bigger turbo.

They are asking $1800.00 for it which is 1,318.50 US Dollars based on todays rates. What you think??

(replacing a few wear items like crank bearings wouldn't be too expensive as long as it didn't suffer something like a broken timing belt and valve to piston collision) Our mechanics charge between $60 and $95 AUS dollars for labour alone not including parts. So it gets expensive really quick.

I really cant pull it apart cause its at a wreckers and their a bit dodgy.

Just out of interest what injectors and turbo do they come with??

Cheers
Matt(replacing a few wear items like crank bearings wouldn't be too expensive as long as it didn't suffer something like a broken timing belt and valve to piston collision)

I have a JDM EJ20G motor that I believe is a Legacy RS, and not an RS-RA.

It is rated at 220hp and came factory with the IHI VF8 Turbo.
It has the ALUMINUM (NOT BLACK) Air to Water INTERCOOLER

If I could find out more about the RS-RA and make sure I dont have it, that would be nice...

Because everywhere that someone says "gold" supposed to be, I have aluminum...

Lol...are u sure u guys arent looking at old pictures from the early 90's that are faded in yellow, making aluminum look gold?

Also..

My motor with the stock ecu should be able to produce 280hp or so at the crank...

what is the best set of heads to upgrade to?
94-96 wrx ones?

and the fuel?

yikies ...

i didn't realize that you didn't have it aleady ...

i would skip on the rs-ra and find a ver 1-2 engine then just use a rs/gt intercooler setup if you want to keep it a sleeper

the heads are WAYY better

http://www.rslibertyclub.org/forums/

i am not sure why you are posting on a US site looking for a motor that was sold in cars that are in Australia. Look on that site, there are tons of those motors forsale.:rolleyes:

Hi Mate
There are very very few RS_RA motors here in AUS. I have been a member of the RS club http://www.rslibertyclub.org/forums/ for over a year and only one other person has one.

He wont sell it to me.. (Ha!!)

Thats why I am now looking OS.
Info is also hard to come by on these motors.

mgfe

Hey Subiekid,
Maybe he's posting on this site because it is known internationally for being a very very good tech resource and has people that know things?:confused:

mgfe,

did you pick up that junkyard engine? That price seemed decent for what it is. But I stil stand by my early advice (that Jaxx seconds) that a '94-96 WRX engine will do the job quite nicely with an updated head design. RS-RA heads are better than you stockers, but they still had hydraulic lash adjusters....

Hi Guys
Matt you got it.... Im trying to ask people who know cause no-one here seems to know a great deal etc etc. Cheers

Mate, I didnt get the engine cause I dont a) trust the source and b) no nothing about its history. Ineed my car everyday so I really cant go without one on the road.

What, where is Jaxx seconds Matt?
had hydraulic lash adjusters.... does this mean tappet noise??

By the way how do you guys go with tappet noise??

We have some cars with the WRX conversion but a lot like mine dont have it.



I got this email from a guy in the Swland. What you think?

hello Matt

Automatic trannies are very sensitive and need a sort of oil, which keeps their sensitive hydraulics clean to work properly. They need a cleaning effect . The same thing is basically true for hydraulic lifters, getting dirt from the engine. The "problem" with ATF is, that it cannot stand the extrem temperatures as normal synthetics, when it is fed through the turbo. So for fullhouse racing i would not recommend this method. We have done it over the last 20 years, in particular on cars, which were serviced before lousy, as far as oil and filterchanges were concerned. We never experienced a problem, in particular as we used only about doses of 6-8% of the sumps content, so it got diluted well. I used it also on my 2L Legacy Turbo with 245HP having now nearly 90 000mls on its back. Now I still get noise sometimes on one lifter, when cold ,shortly before an oil-and filterchange (every 12'000kms/7'500mls), which I am doing with a 10-50 fully synthetic racing oil.
Anyway give it try, you cannot loose only win. In which country are you living? I live in Switzerland near the german border and my Legacy sees sometimes hours of higher revs on motorways with longer parts in the 130+mph bracket.


Try to put about 3dl ( half a pint ) of ATF (automatic trans fluid) into the oil, doesnt harm until you go really racing and change the oil regularly at no more than 8000mls.
We used this trick for years and neary always helped.


regards teddyj

Anyway all thoughts appreciated. Has anyone done this?

Cheers Matt

mgfe

Bad heads?? A friend of mine runs the RS heads on a EJ25 block and the engine pulls hard all the way to 7000 rpm with a VF23 turbo and standard ECU and electronics.

However, the valve tappet noise was there, best solution is to replace the HLAs, not cheap but will save you the hassle for the next 100k mi.

Will do the same on my next engine project -> EJ22 block with E20G heads (with new adjusters).

Hi there
It costs $4000.00 AUS to change and put WRX heads into the RS.

Thats why we dont do it.......
ha

mgfe

where did you-all go???

We're here.;) There just wasn't much more to talk about, so the crickets moved in. Did you ever buy that junkyard engine? What is the status of your car these days?

Hi Matt
Nar didnt buy that engine as I couldnt confirm its history...... Apparantly those wreckers dont have the best name for that type of thing.

My car is going great!!! I have an AUS delivered whit RS T with WRX 02 rims on it.!!!

I have replaced coils...chipped it.....and about to put on a VF 29 I just purchased.

You??
:D

It's in pieces in the driveway. A few more hours of work and the stock wiring harness will be out and I can start putting the JDM EJ20G harness in there.

I think you will be very happy with that VF-29. It has really good spool up and flows a bunch of CFM's. It runs out of air at 7000rpms, but that is all your stock heads can handle, and that should have you over 300hp at the crank anyways...

I second using a little bit of auto-tranny oil.....when ever i do an oil change in my car....i always use about...a third of a quart....if theres any around.....usually is.....not sure how it translates in metric....not positive if it will help in your situation but cant hurt......I can honestly say that i had a vehicle sitting for a while and when i started it, it was ticking...my pop..recomended putting a little tranny oil in it....it works......its also good for cleaning out the cylinder walls when installing new pistons and rings:) ...

H ithere
A few guys here in Melb Australia have talked about it but none are game enuf to try it!!!

I might as I have an oil change coming up. Is there any specific auto-tranny oil I should be using??

Cheers
Mgfe

I have a ej20 sitting on my shelf it has gold valve covers on it. I have never seen this before do any of you guys have any clue why they would be gold
thanks

yes because it could be an RA mtor.
A couple of things that were missed i think
There were 4 types of RS-RA, A,B,C,D. Starting in 1989 with the RA-Record attempt that nailed the world speed record.
B type onwards got the close ratio gearbox.
They have not only gold tappet covers but gold intercooler, hadn assembled and balanced engine clutch and flywheel and differerent mapping. Forged pistons and RS rods which are forged anyway and factory ported heads. Spring rates were increased etc etc bla bla.
Turbo was a VF8 with 15 R exhaust housing.
I have various chassis numbers and applied model numbers for them, gearbox and diff codes and ratios and crap. Also IIRC they have different block stampings which identify them as Genuine RA, its easy to paint rocker covers.
They are quite collectable and i want one, but i spent my money on rebuilding what i have and buying the equivalent STI box. Its still not an RA though.
It will, however eat them for breakfast, with a side helping of EVO3 RS.
hopefully if i can ever finish it.

Hey Man
I might be interested in buying that motor if its for sale

let me know
matt

how do i tell of it is a tru ra. how much is this engine worth?
thanks
brandon

Post some pics of it from front and side and down between the alternator and the p/s pump so the stamping is legible and post here. Also if you know what car it came out of would help if you had the chassis number.

A member here recently acquired a complete longblock with ECU and wiring harness for $950+ freight. I have seen pictures and it is in the car and running. It is the real deal...

i want to see pics of this mystical RSRA engine!

i am headed to the shop in a few minutes with my diggi and will snap some picsfor you guys

ok this here is a genuine bona fide RA complete with a cert from STi in japan, in japanese.

wrong bro STI did indeed exist way back then, otherwise please explain the APP.model code that clearly states STI variant. STI wasnt formed as a "production" arm until 93-94, up to this point i think they just modified the produciton cars. eg RS-RA and RS-R

I stand corrected. Not the first time I have misspoken. STi was founded in April of 1988 with two purposes: Create a winning Group A rally car and get the land speed record (and thus the RA, ie. Record Attempt designation). The above car you mention must be at earliest an '91, as that was the first availability of an STi prepped car. But one thing to be clear on, standard RS-RA's were not touched by the hand of STi. They were a special production version with some specific features on the motors, but only a very small handful of STi RS-RA's were ever produced. STi RS-RA's were built to order...

yes you a re right it is a 91 RA, although it was the B type shape, and produced in march of 1991, before they started the facelift ones in april or may. (which i have) I think they made 400 of each type to homolagate for rallying, but im not 100%. I wasnt at the factory atthe time(at school lol), so i cant say whether or not it was an STI tech who built it or not, but STI definately put their name to it and logos and it. And one thing i can be certain of, they go hard for a 14 year old production car.

the numbers off of the turbo are
vfs9404
215q7a
4412aa041

are you sure vfs isnt vf8?

I will lookagain but i sware it was vfs

I am going to second the Vf-8 thoughts. That 3rd number is definitely the Subaru part number. I don't have access to my FSM's at work, but will try to remember to look it up tonight...

one thing i notice is the metal idle-air-crossunder pipe
mine was plastic

Hey guys, I've found this forum very interesting reading as I own a 1991 RS-RA Legacy (Facelift model) and have been trying to find info about them for ages with little success. This comment caught my eye as I've just completed a total rebuild of my engine and I was surprised to find that my heads had been ported and polished by hand. Possibly from STI!?!?

Does anyone know if there is a difference between the supposed STI "built to order" RS-RA's and the normal RS-RA's? I have a standard "face lift" RS-RA and have noted on it all the specs that people have been talking about...ie. gold high spec heads, balanced & doweled crank and flywheel, forged pistons, larger VF-8 turbo, close ratio gearbox, uprated suspension etc. But it doesn't have a gold intercooler, so I assume this would mean it was a factory assembled RS-RA rather than an STI assembled one. Does that sound correct?

You spoke of Subaru making 400 of each type, is this inclusive of all RS-RA's ever built or only of the STI assembled ones? (I'm just trying to gauge how rare my car is).

Also would anyone know the power output of the RA's compared with the normal RS's?

Cheers if anyone can help!!

I dont actually know how many they made, after rechecking there seems to be some varying info here. But definately no where near as many as the RS base car.
Power i think is up a bit but the gearing and weightloss made the big difference.
Ahm i think they made RS- and RS-RA. there wasnt two types of Ra- just Rs RA, built by subaru and STi.
The intercoller could have been removed at some stage, ? what one does it have now? ill find some links for ya and pm you. I hope you can speak 5 languages... :)

I wanted to chime in. I have my 91' RA engine in my outback. Some day I would love to put it in a early legacy turbo chassis(white of course) and give it back some of it roots. but for now im lovin it in my wagon.

My research concurs. All RS-RA's went through STi's hands and were what most people would term a blueprinted engine. The heads on them were hand finished. Power isn't that much more than the 220ps stock RS, but was 250ps with the Vf-8. And Australian version (which is one of the sources of total production number confusions) had a Vf-12.
But my math says 20 a month for roughly 4 years would be less than a thousand ever produced.

And BTW, I bought that engine from Balistic Motors... :)

Im glad you bought it. what did it come with, and what will you put it in?

I am supposed to get it today or manana and can update at that point. It is going to be put into a '95-99 Legacy sedan. I haven't acquired the car yet, but the parts are mostly collected with the addition of this engine. I have a v6 STI VF-29 and yellow tops that I will be mating to the engine. Not going to use the AWIC either. Probably a real big MRT top mount. I figure at 17psi or so I will have a really sweet 350hp "adult" vehicle... :)

Sounds right up my alley. Look forward to seeing it.

sweet back to the "g" camp again what are you going to use for EM?
factory ecu,link,power fc, autronic?

i just put the td05 on my RS engine -whoa big difference

vf-10 was fun but the td05 is scary .. just waiting for the tranny to blow now (has 176k miles)

95-99 legacy is a good choice .. same suspension as the GC8, a 95 would't have obd-2 issues

if i can get a FXT intercooler to fit (in shipping) ill sell you my standard top mount to get you going ..

95 legacy = obd2
I would buy your top mount for a decent price, college budget sucks.

95 legacy = obd2

Isn't 96+ OBDII? and therefore a '95 OBDI?

I am not too worried about the OBD-II issue. I just think the engine deserves to be in a Legacy chassis, and really like the looks of the 2nd gen cars. Plus, I am calling this my adult build. Leather seats and such for a daily driver. Then I can finish going whole hog race car with the RS and not have to worry about it.

I am thinking a WRX ECU with Street Tuner will be a good solution. I do have to deal with OBD-II testing here, so figure why not do it right, once. Wiring is wiring as far as I am concerned.

It came pretty complete. I am selling the turbo, AWIC, oil cooler and a number of bits off it like the coils and whatnot. Essentially, the only thing that will be used from the engine is the block and heads. Beyond that, it will be a total custom factory like install. I learned a lot from my first EJ20G in the '90 and can pretty easily put together a factory set up with my local parts connections...

Its too bad you have too be OBDII tested.
Fewer wires(OBDI) are easer to wire.

I might be interested in some of those parts. I am having a strange hesitation(stumbling). It wants to die right at take off. Then it stumbles badly when it starts to boost. almost backfireing. it just started not to long ago. Im going to start with the fuel filter.
any Ideas are very welcome

Sounds too rich. Try looking into your IAC. They have been known to fail and cause this sort of hesitation...

Isn't 96+ OBDII? and therefore a '95 OBDI?

The Legacy is 95, the Impreza is 96. They changed the Legacy in 95 because that was the year of the new body style. It would be stupid for them to make a new designed car OBD I for just a single year.

thanks matt for the suggestion.
How much for your extra one? your IAC valve that is.

By the way if anyone is curious I can confirm that the EJ20g RA does have a 7500 Redline (thats when the rev limiter kicks in anyway)

If any of you guys are looking for engine parts for a jdm ej20 let me know.
Matt glad to see your engine finally got to you. :banana:

what parts man??

How much for an IAC and perhaps a set of coils?

ho does $10 plus shipping for a iac sound make me a offer on a set of coils
thanks
brandon

pretty much any stock engine parts

what parts man??

hey matt do you have a picture of the v.6 injectors i went to change injectors yesterday and A: broke it as i removed it B: it was a differnt style than what i thought it was going to be
i have a set of 550cc side feed sr20 inj. (and N/A subaru) injectors which are quite differnt than the inj that i pulled out

i pulled the rail off my 1.8 scrap engine and the injectors fit fine and the manafld bungs line up but the bolts on the manafold are off ...

Sorry,
No pics currently, but I am trying to borrow a digi cam to get pics of the RS-RA and other stuff for people. I was having a little trouble getting mine out of the rails and decided that when it came time to build, I would send them out to RC to be cleaned and let them "professionally" remove them. BTW, my RS-RA ones are the grey tops. My v6 ones are yellow tops. Don't know yet if I will bother to change them or not...

Brandon,
Yes, I got it. We had a few hiccups to work out, but I would give you the thumbs up from other interested buyers that might come to you. I broke my IAC getting the engine out of the trunk the other night. Any chance you can throw on in with the coolant tank?

I modified an updated all metal header tank to work. I didnt like the idea of a old plastic one. Does anyone know how or where I might post some pics of my RA?

Do you know what the "grey" tops flow?

http://www.kineteria.com/share/MVC02357.JPG
550 sr20 / rs / 1993 1.8

noah sent his to RC then are 425cc

i have a spare IAC too

I thought Noah had brown tops. Aren't they rated at 390, but his tested higher?

The factory seems to think they are 380cc, all the ones ive got flowed were between 390-398cc/min

the 2.2T (pink/redish) are 390s
the coloring is off in that picture they are sorta brown
i forwarded this thread to noah perhaps he will chim in

425 comes from 2 places noah and the from the sds aircraft page search subaru+injector+sds 2 pages worth
they have a picture of the G injector and claim 425cc at 38 psi (low?)

I had the injectors that came with my EJ20G cleaned and flowed at RC Engineering. I'll have to find the paper work to be sure but if I remember correctly they all came out at about 440cc. Same as the WRX injectors.

Matt, are you going to rebuild the RA motor or just drop it in? Wish I had one here to tear down so I could see the diferences between it and my motor. Besides the gold valve covers of course :)

Noah

Besides the gold valve covers of course :)

That and the mirror polish on the intake ports and in the intake runners. We pulled the manifold off and both of us looked like --> :eek: , then --> :D .

damit man buy a box camera take some pictures ..then get a cd made when you get them devloped and post some pictures

ill host them if needed

Jaxx,
Shoot me an e-mail of where to send some pics. I have taken some.

And I wasn't planning on rebuilding it from the ground up, but pulled the oil pan and there are major shavings in the pick up. The bottom end is bad and a full rebuild is on order. I am still working out the details with Balistic since this was supposed to be a good engine. Once that part is sorted out, I can remove the heads and take pics of the pistons. But as Paul mentioned, the port work is artful. Also, something I didn't realize before delivery is that the headers are equal length tuned headers. These are factory units, but they are way different than normal turbo headers...

Any way u could post some shots of the headers as well?

was the headder like this
http://home.velocitus.net/jaredw/images/MVC01761.JPG

Like the top one...

that came on my engine too

the bottom one is from a usdm WRX
they are interchangable .. probbaly just a cost cutting measure

so you gonna send those pictures or what :P

http://home.velocitus.net/jaredw/images/MVC01762.JPG

Yeah, yeah. I just forgot the camera last night. I have some basic pictures, but don't have the port pictures yet...

my JDM legacy RS has the top headers, same as RA. i think all JDM RS got those ones. They are heavy suckers and the port matching is crap as from the factory, one was about 3 mm overlapping.

Well,
I think it may be an early vs late thing. My other EJ20G did not have those same headers. It had the little shorty ones...

was your first G a silver intercooler (older version)
?

I thougt the silver AWIC were exports to the UK? I could be wrong.
BTW speaking of intercooler color only the A,B, RA had gold intercoolers the C,D had black ones.

http://www.decal-co.com/out-flat/variation-e.html

My first G was a black AWIC, and I am pretty sure it was a '93. As best I can tell, my RS-RA is a '91.

And my understanding is 89,90 had silver, and after that they were all black, except RS-RA's...

You are probably right about the RS and GT.
Did you look at that link? It shows the product brochures. It looks like we have the B type.(No decal on a Gold intercooler) The A type has a decal on a gold intercooler. the C & D types have black intercoolers.

Yeah,
That link is posted earlier in this thread as well. ;)
My engine did not come with the original AWIC, so I am left to figure it out from other features of the engine, like the oil cooler and the manufacture date on the timing belt covers...

Ohh.
so whats the plan for the engine? rebuild?

Well,
The bottom end is bad on it (still trying to negotiate a resolution with Balistic) so a full rebuild is required. It will be rebuilt stock, but rebuilt nonetheless...

Matt,
To bad you have to rebuild the motor. I hope you take a lot of pictures though :) Also send off those injectors to get cleaned and balanced so you/we know what you got. If they are bigger than mine and will fit I may have to find a part#. Also I was told by the guys at RC that my injectors could be replaced with some nismo pieces but I don't know which ones. Any one know what we can get? I do have a set of 98RS fuel rails I could use if I have to.

Noah

reddevil on here has a supercharged legacy w/nissan 370cc injectors in 92-94 NA legacy rails. i have a set of 440cc injectors from a V6 i believe, and they drop right into 92-94 NA rails.

Do you know if the 92-94 NA legacy rails are the same rails that came on our early model EJ20G motors or are they the same rails as what came on imprezas here in the states?

the 440cc are off a nissan V6, or? my injectors are 440cc so i would like to find some 550cc or so.

thanks,
noah

no see this thread http://forums.nasioc.com/forums/showthread.php?t=777506
i made the sr20 injectors work

the mounting tabs on a G point toward the throttle body
the NA rails point away from the throttle body

you have cut the tabs off the G rails
and have them Tig'ed on to the the NA rails
other than that its a bolt on procedure
the NA rails are 1/2 longer at the fuel pressure regulator (no big deal)

another option is to talk to the sand rail guys they have a top feed rail+injector setup for 400

A third option is to use the rails from a '98 DOHC RS. They will bolt right up and allow you to use all manner of different injectors.

One of these days you guys will see some pics of this fabled motor. I keep getting caught up in work and whatnot and forgetting the disk sitting on the counter at home...

just bumping this thread so that every one takes a turn to kick matt till he posts the picts ..

lol
Get Ballistic Motors to give me a partial refund a get me a new one for selling me a motor with a bad bottom end, and I'll post some pics. I want to tear into it and take a lot of pics, but until that is resolved, I can't break the importers seals on the case...

Since we are on the subject:

I got my RS-RA Running, again thanks to Jaxx and Matt.

My question is: Is 17psi normal on the RA?

My setup is stock; ecu, intake, ect...

Only mods: 3in DP, Sti cat back, K&N

I thought this was excessive so I put my MBC back in and set it for 15psi.

Ben

ya that seems like alot .. perhaps a differnt restrictor

Please expain.

ive heard of quite a few JDM mapped RA's running 16-17 psi, so its not abnormal.
There is some confusion though because my mate up the roads one only runs 10 psi with its RA ecu. So it all comes down to what ecu u have.

restrictor .. inside the hose that bleeds off the boost in between the wastegate and boost control solenoid a metal bead smooths and restricts the escaping air to a given amount.

remember the 3/16 mod ... same thing, might try a smaller restrictor or connector

I thought I would bump with some pic of my RS-RA engine before I gave it a new home.

Are you thinking of selling it?

wooooo

got the harness and all cool

Are you thinking of selling it?

Nope,
He's got it in his Legacy GT.

I finally got mine mostly torn down. There was a lot of drama around it because the bottom end is bad, and I wasn't willing to dismantle it until I had reached an acceptable agreement with Balistic Motors. We finally worked that out last week, and they kicked back some money. I will be sending Jaxx my pix in the next day or two, including pics of the inside of the intake ports( which are a work of art in themself), and the factory forged pistons. :devil: :D

Naphappy,
I didn't see this in your pix, but take a close look at your heads where they mate to the block. Instead of a serial number, since they are STi prepped heads, they should just be stamped with an "S". At least that is how mine are.

Yep. I never saw it before but I have a single S :banana:
Its the simple things that bring Joy

http://www.thawa.net/gallery/My-RS-RA/DSC00447

I thought you would like that. This is a real tell that others can use if they ever come across what they think is an RS-RA. Gold valve covers could be swapped to a basic Ej20G, but those heads are a dead giveaway.

Ok, next game. Go under your car, pull off your heat sheilds, and see if you have the factory equal length headers...

yeah but even my ej20g had those.

and a better description would be "driver side equal length cast headders"

yeah,
I realize that was not an RS-RA only feature. But over on RSliberty we've been trying to sort out exactly which cars those came on...

Yeah mine has those.

Here are some pics of the Engine Bay.

http://www.thawa.net/gallery/My-RS-RA/DSC00449

http://www.thawa.net/gallery/My-RS-RA/DSC00450

The wierd metal thing above the turbo is an aluminium heat shield I made, I know its ugly.

Dont make fun of my BOV. The one that came with it was leaking boost. I have a Stock WRX one, but until I figure out how to mount it this one will have to work.

Nice clean install. I see you used the WRX overflow tank. I plan to do the same.

I think I will start a new thread with a list of things I did.

Are you thinking of selling it?

Everything is for sale for the right price :lol:

You guys thought I'd never post pics, didn't you???

intersting .. too lazy to register
what size socket woudl fit in the standard G heads?
what color are the injectors :P

Those pistons are impressive. Full skirt and huge top ring land. They also look extremely heavy. A weight comparison to a modern wrx or sti engine would be interesting.Also notice they are flat top. The CC of those heads must be HUGE. I would like to see a pic of the valve train.

Jaxx, you have a PM.

Steve,
I will weigh them. I've got NA EJ25 and STi EJ257 pistons, and will have a set of standard cast Ej20G pistons out of another block shortly...

Matt,
thanks for some pic's. finally :)
do these pistons stick out of the block slightly at TDC?
from the photos these look like the ones that came out of my early EJ20G motor which also say ART on them but were not forged.
i would guess this motor has an 8.5 to 1 compression too, but do you know for sure?

noah

oh and i know you probably already covered this or posted pictures but does the motor have solid lifters or hydraulic? i think i may have even already asked this question and gotten and answer. but i forgot and i'm lazy.

noah

Noah,
They do clear the deck. Interesting about the pistons. Mine are pretty clearly forged from the subtle machine marks on them in various places where they were ground down (like around the wrist pin area)

And yes they have HLA's. I had seen conflicting information on whether or not they were solid or HLA's. At this point I am guessing that the actual motorsports ones were solid, but the standard production ones were HLA's...

i though they run 8.0:1

i though they run 8.0:1
You thought wrong. All the early EJ20G's from Legacies are 8.5:1, as are some of the early wrx versions as well.


So, I made an interesting discovery last night. These heads are numbered. While they are stamped "S"(presumably for STi) there is a serial number elsewhere on the heads. It is located on the front side next to the exhaust cams. They are matched sets with R&L designations and mine is number 749... :banana: :disco:

it is cool that they are numbered. I could never find any serial number on the heads of my EJ20g. it would be really cool if STi could provide you with some history with that #.

noah

Noah,
I hadn't thought about that. Maybe it would be worthwhile to see if there is any provenance to my engine...

Matt,

Ok,
I took a look at my other Ej20G motor now that the heads are off. At first glance the pistons look the same, but if you look closely the non-forged ones have a dime sized circle dead center on the piston. Side by side it is pretty obvious which one is which...

the forged one should have a wider parting line also. if you can see the parting line that is.

Hey Noah,
You don't still have any pistons for that block do you? I need one "B" cast piston or a whole set of WRX takeouts..

My WRX and RS legacy manual says 8.0:1. It is the factory service manual

Wouldn't be the first time they made a mistake in the FSM...

Yep I have Two different FSMs and they both say 8.0:1

Interesting

http://homepages.ihug.co.nz/~ccgrant/legacygtrsbc.htm

this page shows the RS having 8.0:1 and the GT having 8.5:1

Very interesting

Matt,
I should still have the entire set of pistons. I suck at remembering to check on that stuff though. But I'll try and find them tonight when I go home. If you get a chance email me at noah19@comcast.net and remind me.

noah

Or maybe I will call you. I still have your number...

well the GT is a cast setup and the RS a forged ??? so why not have differnt compression ratios too
the vf-10 is certanly alot smaller than the vf-8

i found the pistons from my EJ20G and i looked at one and it didn't say ART so i was wrong about that. i'll have to look at the rest of them and see or maybe it was the 02 and up pistons that say ART. hmmm i must be gettin' old :)

noah

i thought it was the forged pistons that said "art"

Only the RS-RA has forged pistons not the normal RS.

Good point, the 8.5:1 would make better use of the smaller turbo.

i think you are correct. i bought a second set of pistons for my ej20g and they said "art" on them. i didn't realize they were forged and assumed it was on all the pistons.

noah
