im new to the forums just got my 91 na with turbo swap. the turbo is brand new. it says ct26 on the compressor housing, the guy that i got it from said its a ct26 with a supra compressor thats upgraded to the 60 trim wheel, and the turbo is clipped(said would help for higher rpms). also have made a water to air setup on it. i read up on here about the ct26 and everyone says about 15psi is danger. my question is with my turbo upgraded and the water to air what could i push that turbo up to(psi wise)
thanks for the help

Turn it up until you knock, then back it off a notch.

Just kidding.

If it was mine, I would run 18 psi max. You might be able to run more, but you're starting to stress the fuel system, which would lean you out and set you up for knock.

I have a CT-27 (50 trim) that I run at 17 on the stock Intercooler without any problems.
