1998 Impreza Outback Turbo Swap

Featured Replies

Hello,

I am new to Subaru, but definitely not new to doing all of my own work on cars.  I need a lot of help figuring out what engine, transmission choice is best for a turbo swap on this car.  I have a leather optioned car, and I want to build a sleeper that looks automatically like a non-turbo car because of the look, and then totally destroy any unsuspecting fellow that thinks I am running a 250,000 mile clunker.  The car is headed for the paint shop.  Not a single piece of trim, or interior is in the way of a beautiful shiny professional paint job.

It will show.  Now how to make it go?

I try reading quite a bit.  I understand I need a different cross member to clear the up pipe.  Which one?  I need the sway bar too?  Which one.  I really have no idea what I am doing as far as determining what will fit.  

The car is an all wheel drive automatic.  I prefer automatic because I am lazy.

Any help would be appreciated.

Your best option is to find a complete donor car, in this case a wrx. You can swap all of the wiring and a lot of the interior stuff. As well as the entire suspension, crossmembers, and fuel tank making it a complete swap electronically.

Why? When you can buy a wrecked 02-05 wrx for half that from an auction. And have access to REAL tuning options from Cobb to open source tuning software. Not to mention parts and upgrades that are more readily available in this country.

ehem */s*, buu buuh its not original, and won't be plug and play!!

Hmmm.. still, once installed, it will run like new right off the bat since it's "stock" (Super /s)

Again, not likely. It has been said many times over that the jdm engines don't run exactly right on our fuel. Which is something that can be tuned for, but again let's just ad more money to a swap that already costs double what a donor car will.

Not mention it would need tuning work as-is, for the different body dynamics and just from sitting around so long, no?

I hope you realize I was just playing Devil's advocate Bratman, "/s" <=> sarcasm

I'll stick to buying N/A, and come to you if I need help throwing one on ;D

I figured you were lol, I enjoy a good debate. And feel free to message me for na trivia too. I've got an na build that I've never seen documented in my legacy right now lol.

Would be helpful if we knew what car you were talking about already having. 

Don't feel bad, Bushwick.  Pertinent information should be included in the body of a post . . . even if it's in the title.

I really don't see it mattering too much, the original poster hasn't been back since he made this thread.

No doubt not used to the addictive properties of the board :grin:

 

Bratman, what's the word on this legendary build? EA, EJ ReverseFrkn?

If putting it in place in an ea81 body you've got to notch the the frame rails so the heads clear. A sohc swap fits far better space wise. An ea82 body has no issues with that part. Everything else for the ea to ej swap would still apply as normal.

Is there a reason why you guys don't shim the motor mounts instead? 1/4" to maybe 3/8" shouldn't really hurt anything.

I'm just basing that off what I've read, never done a dohc swap in an ea81 body. I have done a basic ej22e in a brat.
