Is this a good idea? I know I want cams and am pretty sure that down the road I am going to put a KB on the car. Has anyone done this? What kind of power increase would I see running them NA?
You would likely see a very minimal, if any, gain running a blower cam on an NA car. Blower cams have minimal overlap to avoid blowing boost out the exhaust on a PA car. This minimal overlap makes them very inefficient at filling and emptying the cylinders on an NA car.
Your car should run fine, but if you do those cams make sure you get the blower to go with it...
