I was wondering if anybody can give me any ideas on upgrading my 2006 cobalt ss. I always owned V8 muscle cars but decided to go a different route this time. I have a stock cobalt, and I gotta say I am totally lost. My first upgrade I wanted to do is a stage 2 kit but with a stage 3 pulley? what do you recommend or can I build my own kit? any ideas where I can get the best prices? thanks you guys!
