Default GTO twin turbo...

Well, after some time of playing around, we wound up building a twin kit with a few tricks in it. Its an LS2 stock bottom end for now with afr 225's and a small camshaft. The camshaft is not 200% optimal for the turbos, but does great with the amount of boost on the car right now. If we build a high hp motor later, then maybe we will change it again. We will see. The boost comes in pretty quick and carries quit nicely. The boost hits about 8.8-9 psi in the middle and drops down to about 7.6 on the top end. Enjoy.

No, its not flywheel either.

Rick

A boost input on a dyno should be standard when dealing with FI. I got one for ours and it is nice to figure out belt slip issues or if the waste gate isn't working well. Ours is good for -30in to +60psi!

Very cool!

Those turbos should have plenty of headroom for more too.

I take it the turbo are top mounted some where?
