Hard to say exactly until you get it on a dyno. Intake and headers will make it breathe little better.

Okay cool. Thanks man! Are there any alternatives to produce horsepower besides turbos? Better yet, are there any other parts I can replace with greater performance results that could increase the hp? If so, what would it be?
