These are best. Throw way the cat (or "testpipe") and fabricate from the forward multiple flange rearward to the factory turbo location. Or you could buy this factory pipe. Last one I saw was $150, eBay or Pelican, good shopping maybe half this price. The turbo flanges can be had for about $25.00 in mild steel.

I boosted a 9.3:1 3.0L to 5PSI with no issues. Calculations say 250HP but probably a bit less. Still very tractable with the base C.R. Don't try to bring the boost on early, not needed. Your 5 speed box will give you the gearing 930 guys wish for and the existing clutch will be Ok.

This scenario was just discussed at length. If you want serious power with some measure of reliability you will be duplicating the factory motor. At that stage you are money ahead to start with a used 930 motor.
