3.0 might break the studs, but installing new is a bit less painfull than installing new (better) ones than splitting the case, Timecerting it, making sure it's straight etc. Money poured into doing this (and that you will do) will easily overshadow selling the engine and buying a 3.2 or 3.0 and "doing it right" from the start.

Please don't read this as sarcastic, it is a genuine question. How would a turbo off of a 143hp (that's what the old saab 900s made in the us) work on my engine that already porduces 175?

'74 911 options delete no sunroof. lowered, swaybars, tie bar, braided brake lines, corner balanced, "s" gauges, 993tt seats, Momo wheel and knob, 993 mirrors, blacked out window trim, H4's, short gearing, S pistons, stand alone EFI, other stuff.
