New SS owner
Just bought a 2009 Chevy Cobalt SS. First turbo car I've owned and worked on. Here's a list of what's been done to it so far.
Haun catback exhaust
Forged bypass valve
Zzp 2" lowering springs
Wondering other than the obvious charge pipes, and cat less down pipe I could do to push my car up to the 400 whp range? Thinking about an EFR turbo kit, but not sure i want to get that one.
