Hello everyone. Does anyone know about the pistons gm sells that are supposedly the TGP pistons? P/N 10070183 Any Info on this pistons would be great. Are they able to handle 8-9 psi? And can you get them in different bore sizes?
a tgp stock puts out 8.5 I know people who are Running 11 PSI on stock pistons...
So these pistons would work fine then? If so that would be alot of help.
Jeff's Top Gun chip puts out 10-12lbs of boost depending on the car... :drinking:
Here are the pistons. This is the Mahle part number, which your machine shop should be able to use to order.
