Does anyone here have a turbo or supercharger on their 2.2l cavalier? If so, can you tell me how much it added and how much you payed for it and how much/little of a hassle it was? Is it worth it? Thanks so much! I was just wondering if running like 6 psi from a stage I turbo would make much of a difference at all.

yes it's happened a better place to ask this question would be on www.jbody.org.
your looking at a 30-40hp boost, i would not run over 5-6 psi on stock internals or without a fuel system upgrade.

it's a really good deal; they also have other cavi parts if ur interested.
