16g turbo

how much psi can a 16g turbo run?

Efficiently? Usually people make the most power between 23-26 psi on race gas. On the EvoIII, anyway...

joe covered what the turbo is capable of running on a 2.0 liter, most of boost choice is about your car though, not the turbo. Also, psi doesn't mean anything in terms of power between turbos. Two turbos at the same boost make different power.
