UM lot of money for that version and good luck getting it! You should research all models and what you will be using this car for. Drag? Auto X? Track? Ralley? You have to decide you want with the car and then decide engine and turbo and so on! Powerful laggy turbo or weaker no lag turbo and so on look into it a bit more. Um reliability depends how you drive and what you will be doing with it and what aftermarket stuff you will be doing. Keep it all stock go 130k miles at least I figure. I am sure other people have done this. All depends if you do wiring swap as well or stand alone and so many other factors. NEED A LOT!! LOTS OF MULA unless you do it yourself like so many of us have done!

depends on how much money you want to spend. I read somewhere you can get a v8 sti short block for 1400 +shipping.

Well, you can get a USDM STi 2.5L shortblock for $1400. But that's just the shortblock, no turbo, intercooler, intercooler piping, etc.

Yuri, your cheapest option would be to swap in a USDM WRX motor, keeping the existing tranny from the 2.5RS (which was 98-01, not 97-01, BTW). That swap is legal in CA, too.

Who said that the EJ25 that comes in the 2.5RS doesn't do well turbo'ed? I have a friend that is running a Vishnu kit and has been for a long time. Heck, he even recently added a water injection kit and is currently running 15psi!!!! Granted, you have to tune VERY carefully with the EJ25. Much like you would if you were turbo'ing a GS-R or Type-R. High compression N/A motors need careful tuning when you add any type of forced induction.

P.S. Read the thread at the top of the forum to find sources for parts, costs and lists of parts needed.

well cheapest not sure about that! Many of us doing JDM swaps; the engine and tranny and so on were very cheap. US stuff will be legal but cops don't know the difference any way. AHAH! Also, will lose lot of power with US WRX to make it street legal. JDM you won't. I am curently getting a chip from australia which will be tuned for 19 PSI and remap fuel timing yadda yadda very CHEAP! CHEAP! I can have a switch as well for regular or crazy street race time! So, all up to you and what you want to do but I recomend going JDM it is way better then US and much more durable. Even friends with STI's would rather have JDM 2.0 then US 2.5. Well that is my opinion good luck and let me know if you want more info about JDM stuff!

for the money and bang for the buck I would just go ahead and swap in a basic WRX engine. It's what I did, and I'm loving it. The aftermarket engine parts are easy to get and the swap was actually fairly simple but very time consuming. It's nothing like an overnight Honda engine swap. The engine bolts directly in but the wiring is the time consuming part.
Just my two cents, Micah

id go with the jdm ej20t setup...and correct me if im wrong but isnt most ej motors (if not all) will bolt up to your ej tranny.i know that they relatvely havent changed much making it easier for the motor to swap right in.of course you will need wrx or turbo legacy crossmembers but the motor should bolt right up.the wiring on the other hand is going to be a biatch due to the fact that almost every year the wiring harneess changed.oh...one more thing,go to nippon motors and they have a ej20t for $650 ducets.and if you wanna twin turbo ej20TT that will cost you $1150.good luck.tell me how it turns out

no its 650 bucks for a single turbo ej20 and 1150 for the twin turbo set up.i recomend the single due to the fact of its ,cheaper,less wiring,only 30 hp less(250 instead of 280),more usable power range. here is the site i was talking about.i left a link to it. http://www.nippon-motors.com/subaru.htm the only bad thing is that part of the wiring harness is cut and it doesnt come with everything you need to get it running.i believe it only comes with the bulk head of the wiring harness.but cheap price though.

There are other places you can get them! Prices very but are cheap. Can get them from canada too. Just decide on a route and see it through. Engines are out there. Go look at my post called calling all convertors and see what people are swapping and read what I replied about the ECU chip for JDM ECU's. Good luck and if you need help or need info PM me.
