EJ22G swap into a 95 impreza coupe (wiring)

[bmxpunk]

Havent got to touch my car since, well I dont remember. Monday? Got some stuff at the hardware store to clamp some hoses and route some PCV lines. I have this BMX track that I am managing and a busy weekend of races, not to mention the previous managers corruption that I am clearing up .

I dit get my mug intake mod made. Its cool. Its a coffe mug for an intake. How random is that.

Natoe, do you have a turbo and everthing? I am trying to think of things that you need that I might have. Still cant get over that you are putting it in a FWD. THat is going to be crazy fast!!! I have an AWD tranny and diff if you want it. I have the crossmember you need to. Its from a 1.8 but if you want AWD CHEAP. I hope your junkyard is pulling through. Ordering is not something you do at any of the junkyards in my town. Just hope you get lucky with their inventory. Hope yours comes soon.

yeah! i am definetly interested in parts to make my car AWD. if you have MSN or AIM you could PM me that so we could talk about that. I also need a front swaybar eventually i think matt m has one maybe, but ya, i paid for a full engine assembly, with turbo, exhaust (with downpipe) and the legacy turbo crossmember and will get it tomarrow. lemme know what your thinkin about your tranny, dif, crossmember, etc.
also, ive never heard of that mug intake mod, sounds interesting but i cant picture it... anyways im goin to bed so i can work tomarrow then get my engine.
good luck with your BMX business!

[bmxpunk]

Thanks man. I dont have any im's so you could PM me or email?

Go to bbs.legacycentral.org and do a search for the mug mod. Its cool. THats all I can say

[Natoe]

One thing im not clear on is the boost control issue. on a stock legacy is the computer controlling any part of the boost? in other words do i have to do anything to make it just run on wastegate with my 1.8L ecu?
thanks

No, the stock Legacy computer does not control boost. The amount of boost is regulated by the integrated wastegate on the turbo.
The Legacy computer will adjust the fuel levels better than your 1.8L computer will, but that won't hurt anything....you'll run rich.

[bmxpunk]

There is a stock boost controller from the legacy. I just mounted mine in the same location (on the shock tower) just the other day. Mine was going to be wired to my perfect power, but now I am thinking of running the Perrin EBCS. Just use a manual boost controller before the wastegate. ( iam pretty sure thats were it goes>)

[Natoe]

hmm ok good to know, i FINALLY got my engine today and started swapping intake manifolds. i heard somewhere that the 2.2t injectors are 480cc which is awesome if true. the turbo is tiny! but its pretty awesome and it looks like its in good shape.
One thing that doesnt go together is the radiator, i dont think i can rig it to use my 1.8 radiator since there are extra lines coming from the tank that is mounted to the intake manifold. What should i do about that?
Also, there are two lines coming out by the passenger side heads that i believe go to some tank by the legacy radiator, something that the 1.8 doesnt have and im not sure what to do with those lines.
Other than that and working out what to do with exhaust i should get it ready to TRY and start (hope hope hope) in the next couple days.

[bmxpunk]

Sorry to knock your icecream to the ground and kick you in the nuts, buit the injectors are only 370cc. Had mine cleaned by RC engineering.


If yours starts before mine, I am gonna drive all the way up their just to poop in your rice krispies.

Good luck. THat is awesome. My honda friends refered to the stock turbo as being smaller than ones scrotum. hm.....

Thats it Mine is starting this weekend. After the bmx races are over, I have allday sunday and monday. And I am going to drive it around the block!!!!!!!!!!!

[Natoe]

hahaha well 370cc isnt too bad anyways compared to the 1.8L's 180cc..
everything just seems to be coming together really fast and with help were actually getting stuff done pretty quickly.
we actually got the crossmember off without detaching the steering from the tie rod ends! just made it so we could twist it out and around haha. just have to resolve the exhaust and radiator issues... then a swaybar soon...

here it is..... *stroke*

[bmxpunk]

Wow you used a tire as an engine stand too?? I thought I was the only one who did that. Hey how do I post a pic?

Well i think i cursed myself by saying everything was going along well...

today when we were swapping the intake manifold, we found that the turbo side of the intake bumps into the turbo inlet piping... just barely but enough to make it not bolt up.

soo is there a solution to this OTHER than gently massaging it into place with a grinder? i think we could grind off part of the intake and a nub on the turbo inlet to make it fit but any other suggestions? ill get a pic up soon to show you what i mean.

thanks
nathan

[Natoe]

Here is the problem... see that little nub on the turbo inlet? i think grinding that would fix it, was this a problem on the EJ20G swap that Matt M did? and again, any suggestions for cooling with my EJ18 radiator?
thanks

[Matt Monson]

What manifold are you using? On the coolant, do you have the overflow tank from the turbo?

[THAWA]

That's the EJ18 manifold. Only VF11 turbos have the notches that way, so ysing any other turbo wouldn't give you this problem. Why don't you use the EJ22 manifold? You won't have to worry about the air injection and EGR and stuff if you do.

[Natoe]

it is the EJ18 manifold, i dont have the overflow tank for the turbo... im confused how the coolant system works for this engine. does the top coolant resevoir link to the radiator? but it has its own overflow?... hmm

if you read this thread youll know why im using the EJ18 manifold.... so i can wire it to my 1.8 ECU.
i am just blocking off the EGR with its own valve.

[Matt Monson]

Thawa,
It was a rhetorical question. The thing is, I don't see the little stub runnners on it. I think the Ej18 manifold could be used if the stub runners were in place, but if one has Ej22 manifold, it is probably a better choice. The catch there is you have to disable the IAC. That's what we did on Bugman's car...

[bmxpunk]

If i could post pics, I would show you my progress. I bolted in and connected all plug for my intake manifold and wiring harness!!!!!! I am headed out right now to bolt in the rear diff and finish routing the pcv lines. I have to do some of my own reworking but I am following the stock routing. Oh, I I just remembered I need to install my Walbro. After that I am cutting the hood to install the scoop. Its not as big as the STI scoop, but it might still be big enough to park my roommates MG under it

I WILL START IT THIS WEEK!!!!!!!!!!!!

[bmxpunk]

So jst so everyone knows, the rear cross members are different between the impreza and legacy. THe leg turbo diff WILL NOT fit into the impreza crossmember. SO tomarrow, I plan to put the whole fr1ggen thing in. With rear disk brakes. I was gonna wait on those til I got new cables and backing plates, but looks like that will wait.
It got too late and I couldn't mess with the pcv lines so again tomarrow.... right after another bmx race.... wooo-hoo a pay-less full time job...

hows it going Natoe?!?!?!?!? I am having a similar problem with manifold/turbo issues, but my elbow is silicone and not fitting well

[Natoe]

matt- are you telling me that i shouldnt run it on my 1.8 manifold???? i bought the engine because you said it would be somewhat easier to use that instead of the 2.2... i DO have the little stub runners on from the 1.8, i just swapped the whole 2.2 fuel rail onto it... if i do use the 2.2 manifold, will the wiring become impossible with the 1.8 ecu???
also im not sure how the coolant system works with the extra resevoir, i do not have a seperate overflow tank for that one...

i just bought an angle grinder so ill be able to grind that thing to hopefully make the manifold fit... i would probably be farther if it werent for my junkyard... they are slower than snot in getting me the crossmember and downpipe. and i had to order an exhaust gasket after the turbo for the downpipe.

bmxpunk- good to hear its really close! i hope its overwhelmingly awesome so i have a lot to look forward to once i work out all my kinks. you are using the 2.2 manifold though right? so what was the problem with it fitting?

[RSmatt]

To allow the turbo to clear the manifold, you can make a 1 inch spacer for between the exhaust manifold and uppipe. It will move the turbo back just enough to give you the clearance you need.

[Matt Monson]

Natoe,
Re-read the thread. I am pretty sure what I suggested you do is move your 1.8l wiring harness over to the 2.2l manifold. Everything plugs in, except the turbo IAC. You just cap that off, and move the 1.8l throttle body over to the 2.2l manifold, and use your 1.8l IAC. And then you aren't dealing with capping the EGR either. Everything else plugs right in; injectors, coolant sensors, PCV, etc. etc. There are two connectors from the 1.8l harness that don't get used. One is the EGR, and the other (sorry I forget what it is called) is for that little black valve on top of the 1.8l manifold that feeds into the intake. Neither of them are essential functions.

Screw cutting and grinding stuff. Use the right manifold and you will be fine...

[Natoe]

ooooooh ok..... sorry i must have taken read something wrong, well luckily i havent done anything critical yet so i can still change that over

again thanks for the help, ill be getting some more stuff done today!

before you get too far how do you plan to retard the advance the 1.8 is going to have wacky high advance under boost.

Jaxx,
Why are you quoting me? What does it have to do with my remarks? And IIRC, I already warned him about this earlier in the thread...
