Ya I refreshed the m30.
Sounded great. Real smooth.
Broke in the turbo cam.

Then when it gets hot it started to knock.

Took it apart and looks like I forgot to put the wrist pin clip
so I need a new piston. The hole for the wrist pin was damaged.

If anyone has a undamaged 91.97 m30b35 piston give me a P.M please.

I have some 91.98 sitting in a box but too big.
