I was wondering how much psi a standard 95' WRX runs at (ie. mine) and if I did increase it with no other modification to the engine etc would it have any bad effects on engine etc.

I have just put a scooby exhaust on it and am thinking of adding a panel air filter but not a complete induction kit... how much bhp should I be expecting?


Any suggestions would be great...

 

Ad, click on the dyno section (top right of screen) and look for similar cars to yours. Every change you make to your engine will have a downside and it's important you understand it and take any necessary precautions.

Get it right and you'll be thrilled. Get it wrong and you'll be looking at a very expensive mistake.

Good luck,

Richard.
