Do some research and search through the forum. These are Pontiac's version of the Chevy Cobalt, check out some of those forums too.
Appriciate it def gonna look into a bigger throttle body and short headersIt depends on what you want to do.
- If you want more H.P, the best results will come from LE5 cams from ZZPerformance. DO NOT BUY ANYTHING FROM SKUNKWORKS That guy is a COMPLETE SCAMMER!!!!
- You cam also get ZZPerformance's Throttle Body Adapter plate and 8 to 8 pin adapter, so you can aput on a larger throttle body, but this WILL REQUIRE a retune of your ECM (and TCM, if you have an autmatic trans car).
- I have a ZZPerformance shorty header and 2.5 exhaust. It will flow a little better than stock and it's a TON lighter!!!
- As far as brakes go, you can get a set of Brembo's froma 2009+ turbocharged (LNF) Cobalt. Those will require larger 18" wheels and probably an adapter plate.
- For suspension upgrades, you can get ZZPerformance sway bars (FE5). You don't need Strut Tower Braces, due to the design of the vehicle.
