So someone just bought a ej20tt on ebay....

[MoclovFlop]

And it's not me :lol: :-(
But it is my firend (STZYGT on here) even after I told him he's crazy and it'll be stupid hard.

But, since he's already bought it there's no turning back now so here come the questions because he's to lazy to do a lot of research.

First things first, He bought almost the whole front clip (engine, TMIC, wiring, ECU, 5 speed transmision, tranny mounts, and random other stuff)

Second, he's got master subaru techs at his disposal, along with welding skills and a subaru shop that he works at.

NOW: I've done alot of research for him and already know a lot of the major concerns/problems/issues (brake booster, cross-member, steering rack, ABS), all of which he's most certain he can overcome...except one. Since one of the turbos will be in the way of the steering rack, is it possible to alter the exhaust manifold/piping to simply move the turbo out of the way slightly? He's already planning on a full cutstom TBE to make sure he can get into the exhaust channel and what not.

Even if this means custom fabbing a new exhaust manifold, is it possible?

I know alot of people just go single turbo, and he's an impulse-buy kind of guy so he didn't do any research before jumping into it, even after he talked to me about it and I cautioned against it.

Let me know what you guys think. I searched NASIOC, here, and a few other forums but what I found didn't answer a whole lot. Also please post links to information on anything/everything you guys know of.
Also, if anyone knows where any wireing diagrams and pin outs for the JDM ECU are for the EJ20tt are please let me know.

I'm not particularly familiar with the EJ20H, so I couldn't tell you about the turbo setup. However, he could just go to a stock wrx single turbo setup without too much trouble, and certainly less than fabbing a new manifold, etc.

He'll be tracking down tons of random parts, regardless of the extent of what he bought. If he was willing to go to that level of fabrication, he should have just bought the full front clip and gone RHD.

[STZYGT]

ok So i know this might have been a little hasty. But i dont know what other parts i am going to need. I have the whole engine management system, fuel delivery system. and transmition. There will be a couple main mountains to climb. One i need to fit it in the chassis. Ok might take a bend or two but im not expecting a hudge fight. then electircal, which i have the wiring for and a electrical genious that i work with. Then cosmetics and tuning and the odds and ends which will just take a little time. But any help will be apreciated. Somthing like this is not impossible just takes some brains and blood.

[rougeben83]

ditch the bi-turbo setup altogether and run a single. It's not really that worth it to go through all the trouble in keeping it. Switching to a stock WRX manifold/turbo/IC setup is possible I think.

[sheepdog]

It's definitely possible. I hate to break it to you man, but it's really really not worth the trouble to keep the twin turbo. It's performance isn't any better than a wrx setup, and the aftermarket/repair parts for it will be hard to find and expensive.

Good luck though

Impulse buying without research.......a recipe for success. :eek:

honestly, that's probably the best solution right there, I've thought about doing it myself, but it's just another project.


I've never had one of those engines in front of me, but I've examined a lot of photos when I thought about buying one and trying to make it work. You'd have to swap the turbos to the opposite sides and build custom manifolds, but with some fabrication skills it surely could be done. The end result will be a whole lot of work for nothing more than really just a cool factor. As others have said, you can get better performance with a good single setup. But on the other hand, if you got it to work with the bi turbo, you'd be the only one who did, even if it wasn't that fast, it would be pretty freaking cool, plus is would be faster than any stock wrx so it sure would still be fun to drive.

[sheepdog]

would be faster than any stock wrx

Actually, I don't believe that is correct. Especially in the legacy chassis, you would NOT be faster than a stock wrx.

[SammyDaFish]

why wouldn't it be? I guess it would depend on the leggy that it was being swapped into, if it's a BD/BG/BK it would be, they weigh in around 2900lbs and unless I'm mistaken, I think the EJ20H makes 265hp. A stock wrx is 3100lbs and makes 227hp. So the leggy should be faster, granted not terribly, but enough to make a difference.

if the leggy is a BE/BH then maybe not so much as they are a bit heftier

[MoclovFlop]

Yea, it's going into his 98 Gt wagon. And in terms of the hassle of the interference, he seems confident he and all of the people he works with, can fabricate up something to move the turbo out of the way of the steering rack. But we'll see, since it's never as easy as you think.

Sheepdog, your more than welcome to help out when it gets here since your in Colorado :wink: especially since you have swap skillz

[sheepdog]

Haha I could be persuaded to sit and stare at the wiring harnesses with you. I'll be really busy until like June though, finals, and then field school. But let me know anyways.

[Plays_with_Toys]

I wanna watch too! But- not so much helping with the wiring. When it comes to electronics if it's not a matter of hooking up power to one wire and grounding the other, I've got two left hands.

[MoclovFlop]

Haha everyone's welcome!!! and yea wiring will be a fun thing to watch. He says he's got it covered and i said i'd eat my hat if it gets done in the time he thinks (he said it'll be 80% plug and play since it comes with the PCM, ECU, and all wiring) I say he'd better learn Japanese. But we'll keep everyone up to speed, and i'll let you guys know what something starts happening when the engine gets here. Then we can all sit and stare....

enh, my AWD outback is around 3000lbs, but you're right, it would be slightly lighter, and more powerful, definitely faster than a WRX.

[sheepdog]

Ha! He's in for a sore suprise. Getting the wiring harness and ECU don't make the job easier.... they make the job possible.

[MoclovFlop]

Haha, yea i figured as much, hence my suggestion to learn Japanese. BUt I hope for the best and if it's sick, I might have to buy my old dream car just to keep up (UrS4 or 92-94 S4 for you unfamiliar)

[MoclovFlop]

Well how about some news?

The engine and everything will be here Tuesday.

And an amazing development.....WE HAVE THE WIRING DIAGRAM!!!!
for everything. Plus all the hose diagrams and turbo operation diagrams. Pretty much EVERYTHING we're going to need. All the specs....all the information all thanks to this website.,..

http://www.veloce.pwp.blueyonder.co.uk/

That just makes everything so much easier. And lucky for him, the auction includes the solenoid box for the vacuum lines and what not. So it should be "easier" to splice the harness and do everything else. :twisted:
