slothball Posted August 22, 2006 Share Posted August 22, 2006 hey, i have a 1993 Subaru Impreza L (front wheel drive) and i have a question. I want to swap my engine with an STI engine and i wanted to see if that was at all possible. If someone could please answer my question that would be great. Thanks, Nate Link to comment Share on other sites More sharing options...
subiefan Posted August 22, 2006 Share Posted August 22, 2006 I suppose the engine would physically fit, but it's ECU would have to come with it. '93 Impreza is OBDI. Not sure when STi's were introduced here, but I think it was after '95. So your STi engine is going to be OBDII. I doubt it if the 5MT tranny in your car is strong enough, either. The STi tranny is a 6MT, but all STi's are AWD. Anywho...you're looking at a major project. If you have a donor STi (wrecked or somthing) and the time, it might be worth it. Honestly though, I'd drop in an ej22T from an early turbo Legacy if you want more power. They're plenty powerful, and reliable too, and the 5MT from your Impreza is sturdy enough for it. It pretty much bolts right up. There's some electrical work involved, but there are a few people around here who have done it. Link to comment Share on other sites More sharing options...
