I have asked this question a couple of times - no reply

Please help! can anyone tell me the standard boost pressure of a 1995 WRX (import)? I have not bought a boost gauge yet. What boost can I run safely with only an exhaust?

 

I am sure standard is 10.5psi

I believe the max boost you can run is 28psi (not safely though)

 

No the pressure standard is 12.7 psi and tha max you can run on the standard map sensor is roughly 18 psi.

Cheers
Stuart
