The manifold from Gm pp, does it add Hp? if not, what does it do?

how come when i asked about an intake on my 2.0, it showed up on their system, and he was gonna put it on for me?

I know I keep asking questions about my cobalt vs other cars, but im not good at figureing it out. One of my best friends just bought a 1999 BMW z3 roadster. Could that take my stage 2 sc?

and prob one of the most asked ?'s ever.
Only GM upgrades are the stage kits and the manifold, and cat back. right?

 

The GMPP header is awful. Get a quality header. Go with CIA, I think they are having a group buy too (or they were anyway).

 

well i am not sure about a z3, but i had a run in on the thru way near albany the other day with a bmw 328 xi and i could stay in front but not lose him. i am stock btw

i believe those are the only gm upgrades besides the steering knuckles.

there might be a cold air kit from gm, but i dont know go with a k&n or injen or rebel intake.

the big thing on racing is skill. skill beats raw power more times than not.

dont feel bad about asking q's. sometimes its the only way learn something. lots of good ppl on here

 

please post in correct forum. moved
