I got a 1998 cav. 2.2 liter with intake and exhaust.... i need to know how much psi my engine can hold with a stock volvo turbo, and an eclipse intercooler... i know people who say i can get up to 5 psi but i dont want to blow the trans... if anyone knows please tell me...

5-6psi

well some ppl run up 2 10 without problems but 4-6 psi is good without upgrading anything

With stock Cavalier head gaskets being what they are....I wouldnt add any boost without a turbo rated gasket.
