Okay, I have cam, heads, everything is in my sig, what else can be done to gain hp? Is NOS the only thing left? Thanks for any input...

 

Forced induction.

 

You could get a better set of heads, I see your sig says 250cfm.....I believe the AI full port heads flow around 275. All depends what you want to do with the car. Bigger heads with a solid roller cam, forced induction, stroker, NOS...lots of ways, just depends on what you want out of it and what you are using it for.

 

Forced induction, are we talking super charging? If so, compression is too high. I readdly dont wanna change the cam, what to much work.
