My turbos showed up today. A pair of ball bearing TC76's with ceramic coated housings courtesy of onfire. 68mm turbine wheels and .81 exhaust housings. I've got truck manifolds on the way here already. I'm going to emulate SOFAKINGGR8's build. I'm trying to decide if 38mm wastegates will work for 10psi and above or if I need 44's. My 403 is at the machine shop getting the machine work done and Clay Forrester of Forrester Racing Engines will be assembling it and building the turbo kit. I've also got the 2000hp rated Magnafuel pump waiting to go in. Air conditioning is retained. The stock GTO radiator needs to be leaned back a couple of inches to fit the charge pipe over it. Intercooler is the bigger of the two Treadstone's with a center top outlet.

Here's a couple pics of SOFAKINGGR8's build.

Found it. http://www.cxracing.com/mm5/merchant...gory_Code=INCO
I'm also debating running no intercooler with E85 and meth injection.
