hey i was wondering.. if i installed a stillin supercharger, could i still put on a cold air intake, crawford headers, UR pulley, and all them other bolt ons, and make the engine produce even MORE power... or will i have to change everything back to the way it was? im interested in the stillen right now because its the only thing that if i get pulled over and cops check under the hood, im not totally screwd (carb legal).

 

not the UR pulley it will lower your boost, and the Headers would lower your power. The Stillen is designed to run on a stock engine. You can use a cold air.

 

You can use the cold air, but the pulley has to go back to stock.
Also, the headers are questionable. you won't lose power but you will lose boost. the SC kit is designed for use with stock headers so when you free up the backpressure, you will lose boost. I'm unsure to weather you will just lose a little boost but make up for the power in the high end. I don't think losing power all the way through is the case but I'm not 100% sure. I'd leave it stock non-the less and upgrade to a stage 3 pulley on the SC myself.
and of course upgrade the exhaust

 

Tony,

Are you sure I can retain my NISMO CAI with the Stillen Stage 2? Will my NISMO Cat Back Exhaust work okay with Stillen FI? Finally, are the NISMO Clutch, Clutch Cover and Fly Wheel compatible with Stillen FI, or not necessary.

 

absolutely, happy modding.

 

Yes the clutch etc.. will be compatible, i don't understand why they wouldn't be. If you are talking about able to handle the extra power, yes you're fine.
The intake shouldn't be an issue, although stillen recomends that you use their intake/airbox etc...
And yes the nismo exhaust will work just fine.
