[lewi]

What internal engine mods need done to a 95 m3 motor to handle about 10psi on a vortech sc or aa turbo kit?

This has been discussed many times before, the search button is on the top right.

But to give you a basic answer, almost nothing internally. The compression can be dropped safely with a gasket and therefore no need to go to dished pistons in the range you are talking about. The s50/s52 internals are good to ~450 rwhp so far, though some people are pushing more.
