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 They use an old outdated head design.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!

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.

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.

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.

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...

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??

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. 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

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

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.
