I meant stock internals. Although the Ca has an iron block, anything over 300hp (and 17-19 psi) is pushing the threshholds of the stock internals of course. That's why i'm looking for a good aftermarket online retailer with nuff parts 4 a head rebuild, turbo, pistons. Everthing else (ecu, piping, boost controls, fuel management etc.) should be almost common sense when upgrading.
