Cam and pistons are not really usable on a turbo motor. Stroke is probably a 3.59" or 3.625" and rods are probably 6.5". So, if you were building it you would need dished, valve reliefed pistons, and a S2 cam if using those heads. If using those heads, you will have to either delete the ac box, or at the very least modify it. Then the intake has to be modified for efi, plus headers, plus piping, plus a big ass turbo and converter to push airflow for those S2 heads. Etc, etc.
Or run the S2 bottom end, get an on center stock type intake and good stock style heads and use your stock headers, etc. This way you would have a near bulletproof bottom end.
Or just send it all to me. I will put it to good use.
