I have a 2003 cavalier that I race circle track in I have a .020 head gasket 2.4 intake and supercharged colbalt exhaust manifold. I will be installing a stage 2 cam set my question is what size injectors should I upgrade to and do I have to go aftermarket or can I find some that will transfer over from another car thank you all for your help

they are a little shorter but usually with the factory injector cups they fit no problem.

Yes you need tuned to make them work correctly and give you a increase in power. This is all saying you need bigger injectors.

That is correct. Cobalt SS 2006

You will need to find the injector constant before it can be tuned. Look it up, I think I posted it a while back.
