this show i saw on tv took a stock cobalt ls and added the hahn racecraft turbo along w/ a stroker kit(new pistons, rods, etc.) and it put out around 240 hp. they also got the first catback for the cobalt from dc sports.
Well the main thing to remember is they swapped internals as well to compensate for the new forced air inside the motor. So plan on facotring in some decent pocket change if you want to go all out and at the same time be reliable as possible.
Yeah but if you think about cash you also have to realize that you can get a used Eco Cavy for like $5-6K (around here anyways) only thing is findin one with a 5spd... too much trouble for not enough reward to look for one... And if I was gonna go that route then Id opt to buy a limited slip, which would tac on another thousand bucks or better prolly... Moddin anything can get very expensive....
At the track I go to some guy from Ill. has a CAVALIER that I think is a 04' with the 2.2 Eco motor, he put a Hahn turbo on it and at the last import war he was running [email protected] If he could hook up he should be running in the low 12's.
