dp213 Posted June 7, 2014 Share Posted June 7, 2014 Without buying a STI motor. Is it possible to get a lot more power out of my 97 dual can 2.5? Quote Link to comment Share on other sites More sharing options...
lmdew Posted June 7, 2014 Share Posted June 7, 2014 (edited) Anything is possible with enough $$$$. Comes down to how much you want to send and the reliability of the engine once it's built. Read the Franken Motor thread. Edited June 7, 2014 by lmdew Quote Link to comment Share on other sites More sharing options...
Baja rally 05 Posted June 7, 2014 Share Posted June 7, 2014 It would be cheaper to go with an STI swap. A lot more power just with the swap only then with some basic mods even more power. The only way to get way more power with that motor is for it to be turboed and it would just be cheaper to do a swap Quote Link to comment Share on other sites More sharing options...
dp213 Posted June 8, 2014 Author Share Posted June 8, 2014 I haven't found a STI motor for less than $4000. Would it cost that much to turbo the 2.5? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted June 8, 2014 Share Posted June 8, 2014 (edited) I haven't found a STI motor for less than $4000. Would it cost that much to turbo the 2.5? what you're missing is that people pay $4,000 because there's no cheap/easy/effective way to do what you're asking. if it were as easy as you think, they wouldn't cost $4,000. the exhaust work could run $1,000. done right, it would cost more than $4,000. turbo, custom exhaust and/or crossmember work, install turbo pistons, higher flow injectors, and an aftermarket controller (ECU), EGT monitor, wide band O2. forced induction engines have low compression pistons, non-turbo engines have high compression pistons. forced induction and high compression pistons don't play nice. that's what you're asking "can i put a turbo on my high compression short block?" yes - but it's a very risky and power is limited. you can put a turbo on it and run very low boost, the stock ECU and injectors can handle a little more flow. be careful though, a big KABOOM isn't far away.

Rooster2 Posted June 8, 2014 Share Posted June 8, 2014 After reading the previous posts, you can see that there is no cheap and easy way to get a lot more power for a N/A Subie engine. If it were me, I would trade up to a WRX that is designed and built to have more power. Quote Link to comment Share on other sites More sharing options...
