Default GC Wagon...swap in the future

Okay guys, I've worked on several Nissan and Toyota swaps, but never on a Suby. SO I have my 98 impreza wagon. I work with a Non-Profit Organization called Donor Dudes to promote Organ, Tissue, Blood, and Bone Marrow donation. We're talking about using my car a a promo vehicle. It'll be driven on the street daily, showing our logo and weB address, and also used in weekend races here at our local Utah tracks.

Right now here's what we're thinking:
1. EJ20 from a wrecked WRX at a local junkyard.
2. Heads are ported/polished by a friendly local machine shop that does wonders with flow.
3. We're considering the JUN 2.2 stroker kit...but haven't heard anything about it yet...still looking into options for engine internals. Out goal is 350 WHP.
4. We're going to Quafe for front/rear LSDs.
5. Polyurethane suspension/chassis bushings.
6. Adjustable coilovers
7. Anti-Lag

As you can see, we're in the early stages of R and D.

Here's what we don't know yet.

1. Still not sure on engine internals/EM yet..any suggestions?
2. Anything we should do to the stock WRX trans? We would like this car to last for a while...We're getting local businesses to sponsor us, and would prefer to not have to ask for money from them all the time.
3. Who should I go to for suspension parts for my car? I haven't found any yet...aside from eibach pro kit springs from TireRack
4. What is the best way to go about our ALS? I've seen it done with an auxilliary injector that squirts into the downpipe, but that doesn't seem safe to me. I think I remember reading that it's done at the ECU by playing with the mixture at low throttle....don't remember now. I'm spending too much time studying Japanese for school right now....
5. Also aren't sure about where to go for cams.

If I'm thinking correctly though, COBB tuning has a shop or something out in Tooele, I should go talk to them too.

So, suggestions and advice are always welcome..it's a rough concept right now that will probably come to fruition in a year or so.....thanks.

Anyways, what he really means is a GF wagon, as a GC would mean a sedan.

An ALS would not be a good idea on a street car, as your downpipe would last all of 500 miles or so.

You can get STi RA gears for the stock trans, you can get a 6-speed out of a USDM STi, you can cryo-treat the gears, there are many options.

Suspension wise, Whiteline makes good sway bars, endlinks, bushings. There are many coil-over setups available, and most of the suspension for the WRX's will also work on the earlier bodies. As far as internals/EM, since your using a WRX motor, anything that works for a WRX will work for you, and that's a question for the 2.0L turbo forum.

If your considering the JUN 2.2L stroker kit, you'd probably be better off just swapping in a 2.2L motor from an older turbo legacy. Closed deck block, piston squirters, forged internals... basically the strongest factory block built.

Another option would be to go with a JDM STi motor, which is rated (stock) at ~280hp. The initial swap would be more difficult, but the starting point would be much better (stronger internals, better heads, comes with a stronger trans...)

A third alternative would be to find a crashed USDM STi, and swap the drivetrain from that. Again, a bit more expensive up front, but in the long run it will be cheaper.

Hope this gets you started!

for the block I would do either a EJ22T (old turbo legacy) or an STi block...for the heads be sure to get cams...for antilag be sure to get a really nice ball bearing turbo and don't use the antilag much...oh and a very strong/durable/burn through resistant exhaust system...
one thing you need to adress is the tranny...gearset I'm assuming...???
or save all your diff and gearset money and just get an STi 6-speed swap

for what you are seemingly wanting to do, the work could be circumvented by just buying a wrecked usdm sti with ej257 driveline. drop the sucker in, get some reflash and a turbine and 350 awhp easy with 6mt gearbox. nil labor required.

the 22 is usefull, but a bother. why bother to build a 2.2l when you can get a new 2.5 liter that takes care of businesss much better.

You will take your money the farthest by getting a whole JDM STi drivetrain, version 7, 8 or 9. Get the motor, tranny, brakes, wiring harness and ECU. If you go this route you will love your self later. An EJ207 can handle 350whp all day with out modification. you can save a lot of time this way because you will not have to open the block and wait for machine shops. Unless you have big bucks stay away from Jun.

And ALS does not belong on a daily driver, as said above.

Yeah....GF is what I meant. I just didn't know at that time.

Yeah, I've been looking around on here and the JUN kit seems to be something to stay away from.

I know that Venus up in Sacramento has some GC8 STI swaps available...not sure on the price though. Thing is, I'm going go rebuild whatever used motor I get because I want to start out fresh on it. Had a buddy recenly swapped an SR20DET into his 240 and fried the rings after 10k...supposedly clean low-mileage JDM engine. Will I have a problem getting the internals for the JDM motor?

As far as ALS, ummm the plan is to have it non-functional most of the time, only use it for the track. We're researching how to do that and I have a buddy here who is a wizard with building exhausts, I'll have to talk to him about it.

I was wondering about STI motors at first...and yeah I think you guys are right, as I look into this stuff more.

How dificult is it to mount the EJ207 or 257 into the GF chassis? Is it going to require much custom fabrication on that end?

Thanks again everybody.

for antilag Id go http://www.autronic.com/page_files/sm2_kit.htm heard it works good on a subaru. For tranny, gruppe s version 6 STi ra 5 speed and for motor there was a thread a while ago I think which showed that if you mix the stock crank from the 2.5 with a wrx block and some internals you can get close to 2.2, not sure about this.
