around 7-9 psi depending on gear, outside pressure, and a few other variables. Same thing as a turbo 2.0.

you can boost with cast pistons, but tuning has to be dead on. detonation is what kills pistons, but if you have your tuning right, you wont have detonation. forged pistons are stronger and can stand some detonation, but if tuning is to far off, you can still kill foged pistons.

i wouldnt boost an N/A 1.8 or 2.0l. the turbo motors havea lot lower compression (8.0 compared to 9.0 or higher on the n/a), again to reduce the chance of detonation.
