So I just installed a TB0357 Saab Turbo w/ a/r .42 compressor, a/r .48 turbine, and .45 trim Manifold w/ external wastegate mount Tial Wastegate at 11.6psi. and a Large Front Mount Intercooler

So my problem is that I am new to the whole turbo thing and I seem to only be getting about 3 psi. and lacking the HP gains that I expected. I was wondering if anyone knew what my problem is or if there is a way to get more boost?

 

check all your connections make sure you don't have a coupling blown off as well as vaccum leaks. The front mount may be to big and you are seeing excessive amounts of pressure drops through it.

What size motor is this own?

exactly, sounds like you have a boost leak somewhere, or you have a large exhaust leak before the turbo

 

The motor is a D16Z6

 

It's definatly not a pressure drop in your intercooler. Sounds like a boost leak to me. If it were an exhaust leak you would be able to hear it.
