you think a stock maf will allow enough horsepower for 330-375HP???? (not wheel)

and in all honesty, i would get a fuel pump, lex afm, injectors, afpr, and whatever tuning devices you like + a wideband before you get the turbo.
the fuel pump is 21 years old... injectors have more then their fair share of crap in them... dont push a system thats not even at 100% yet...

with a full 3'' exhaust and a new IC + pipes. its going to be a much different car. i would rather see you spend the money on the stock turbo and push that a little harder then get the 57trim and not be able to push it at all because you dont have the fuel or the proper engine management.

fuel cut on a stock ct-26 + maf is suppose to be like... 14psi?

You need atleast an air/fuel tune. To be optimal you need to calculate efficient ignition tuning as well. You are beyond acceptable factory tolerances. Sorry.

little more specific? what should he turn the air/fuel with?

and how would he go about tuning the timing with? he would have to get an EMS like AEM... or get the MAP ECU2 to work with the timing control...
