Default Imprezza - Legacy TT swap

I have a MY96 Impreza and am looking in the options for a JDM turbo motor swap. I will also need everything else, so I'm planning on getting a whole clip. My car is an auto now, and I think that I want another auto, I am thinking it will be easier, and it will keep the sleeper look i'm going for. I sent a quote to Adelaide Jap Dismantlers in Australia, and he recomended a 2000 Legacy TT clip with a triptronic auto. He also said I won't need to swap my whole rearend, just the ratio to a 4.4. My questions are

1. Will a 2000 Leagacy Twin Turbo Engine and auto tranny bolt up, and fit in an impreza? If this engine won't what is the best bet?
2. Who make a gearset to swap my rearend ratio, or do i have to swap the whole rearend?
3. What is involved in swapping in a manual tranny (would the STI 6 speed fit?), if the car is auto now, will it be that much easier to just swap in a turbo auto tranny?
4. I nkow I also need a front/center diff, but this should come with a clip right? Will I need new front axles or will a clip come with that as well?
5. I am also looking for a decent suspension setup for the car, what should I get? I was thinking Springs and struts, strut tower brace, sway bars mayeb an X brace in the back, a bushing kit (anyone know who makes one?) and new strut tops (will the STI's or Cusco's work?) I also eventually want to replace the control arms ect.. Are there any aftermarket one available?

Depending upon whether or not you get the WHOLE clip, it might be possible. A friend of mine, Aigburth, dropped a Legacy B4 TT engine in his car, though had to remove one of the turbo's since the engine is set up for a right hand drive car. In essence, it won't work unless you have a right hand drive car, as the turbo on the right hand side of the engine bay has serious conflicting problems with steering functions. Right now, he only has one of the turbo's running, and should be getting it out of the shop this week, so hopefully it'll run!

I'll make him post some info on the whole swap.

The car is a 1996 Subaru Impreza L, though his "was" a 1.8L. I don't have any pics right now, but I can try.

As far as getting the second turbo on, don't bother. You would have to practically convert to right hand drive, and thats a pain in the arse. His plan is to utilize a larger turbo than the dinky one on there now. When I say small, I mean it. I think the compressor oulet is like 3/4"? Mind you, there SHOULD be two of them, so thats a different story.

So, hopefully the car will be running this week, though its gonna be interesting running it off the 1.8L ECU.

The front and center diffs will come inside whichever transmission you decide to go with. That's where they live.

There are many used 4.44 rear gear sets here in America. Any good yard will have a few to choose from. Can't think of the places name, but it's in Sacramento, CA. Great source of used scooby parts.

Bear in mind that you should use the wiring harness that comes with the front clip. The automatic will need its original wiring harness for sure. Running a turbo EJ20 off a US wiring harness isn't too ideal, but the alternative is pulling the dash out and splicing together a mixture of the N/A and turbo wiring. Basically, the wires leading into the engine compartment should be sourced from the donor front clip and the wires behind the dash for the gauges should be the stock ones. Splicing them into one cohesive wiring harness requires great diligence and a factory wiring diagram for both of the harness's.

Bear in mind you might want to look for an engine & auto-trans from a wrecked US WRX. Just a thought.

I spoke with the guy at Adelaide Jap Imports again about the driver side turbo not fitting, due to the steering setup on a left hand drive car. He sent a photo of the driver side turbo, and also said that the car is sold in left hand drive as well so there shouldn't be a problem clearing the turbo?. In the picture the steering shaft will come out right where the AC lines are.

Well, all I can say that I have seen this first hand NOT FIT, so undertake this project if you think you can make it work. But, please bear in mind, get ready for some serious down time, shop time, and money to get this thing to fit.

You think I will be better just going for a single turbo ej20?

I was also wondering if anyone knows the diffrence in size (exhaust A/R, compressor size, and cfm) between the single turo, and the twins on the ej20, which is capable of more power? i'm now begining to think that the single turbo is the way to go, it will be chaper to buy,a nd cheaper to ship I now know of several already in the states

Swapping in a B4 EJ20-TT is best reserved for the right hand drive non-turbo Legacy boys (and girls). I believe you need a custom exhaust manifold if you would like to run the twins. And having it custom kind of defeats the purpose of doing the swap. My suggestion would be to stick with the single turbo EJ20 swap. Then you just need to deal with the details of the swap itself and not how to re-engineer the entire setup.

If you do a full swap with transmission and all, I think you need a new transmission crossmember, but I could be mistaken. You will also want to get the full EJ20 wiring harness because the auto tranny ECU's expect a TC signal (atleast the RS's do). Go here and look at the Project EJ20 link.

Oh, and TRP (Tony Rigoli Performance) did a B4 swap into an Impreza. But that is the only full swap I know of. Read the article and you will notice some of the quirks they had with the ECU.

If you want to do this, find a Legacy Postal Wagon. Its basicly a RHD brighton wagon, so its both setup to use the TT motor, AND light.
