Wastegates

When ordering a new wastegate you can select any spring/psi requirement

*GT II Wastegates are 2/3 the weight of the GT and include all springs for boost change.

T-N-C is the first known to produce flanges for the GT12 Turbocharger.  We cut these flanges in 3/8" Stainless only, the outlet flange features an oval hole for a better flow from the internal Wastegate.  The oval is based on a 2" pipe size which can be easily produced from a 2" pipe even in a regular shop vise without heating of the pipe for a perfect flow transition.  These are sold together.

Part # TNC-4055 $65.00

Also available is a stainless oil feed/return flange for the GT12 which includes a copper gasket for leak free operation, stainless bolts included.

Part # TNC-4056 $40.00

After many years of building custom turbo kits, we could never seem to find a T3 outlet flange we liked, and our customers felt the same.  Our answer, we have designed and cut our own.  Our 5-bolt T3 flanges are cut in 1/2" stainless with extra material all the way around, but the best feature is we cut them with a 2.5" or 3" hole to allow the respectable size pipe for the flange to be fully welded inside and out.  This design prevents the stresses on the downpipe from beaking at the weld and insures a leak-free operation!

Also available the famous T3 inlet flange itself, 1/2" stainless through hole design.
