I am wanting to raise the boost on my 93 imported WRX, I have done the exhaust, brakes, suspension and made a cold air intake for it. Its currently sits on 11 PSI in all gears. How far do you think I can go without pumping more fuel into the cylinders? I run her on 98 octance gas if thats any help. I have read that you can take the older legacys which run same engine upto 1 bar no problems but the wrx runs a slightly higer compression ratio so that would make a difference. I am sure there are others here with similiar setups to mine what are you guys running?

I am sure this topid has been addressed before but with no search function on the site makes it kinda difficult to go back and look

Thanks people
