Well what year is your camaro? If it's 93-95 It's a 3.4. If it's 96-02 it's 3.8 anything earlier than that is either the 2.8 or 3.1.
Either way, there's not really anywhere to buy a turbo kit for your car. It would have to be custom made. Not impossible just expensive. check out Tiago's turbo'ed 3.4 firebird at this link. He was custom building kits for Camaros/Firebirds but i don't think he is doing that anymore. I think his kits were like $3,500-4,000. http://force-fed-fabrications.com/index2.htm
