GTM Performance Engineering: MHI Twin Turbo Official Release

Mike@GTM

Well, this car currently has some pre-production parts on it. The exhaust manifold it has is version 2 of our manifold that does not require drilling and tapping the cylinder heads. Here is a picture of it below.


The final version is going to be based on the CAD drawing we posted earlier.

GTM Performance Engineering: 370Z MHI Twin Turbo Pre-Release

A 3" true dual turbo-back exhaust is almost always a nice addition, but not a necessity unless your power goals call for it.

You can make 500whp with that combination all day long...with either the 16g's or 18g's with 2.5" or 3" exhaust.

Yes, we offer our pipes done in gloss black for $240. We can have other, custom colors done, but they are generally more expensive and not always readily available.

The test car with 18g's has our 3" downpipes with external wastegates and our 3" cat-back exhaust. The dyno results are with our version 2 pre-production manifold that does not require drilling and tapping the cylinder head. We will be doing some additional testing with our upcoming manifold you saw the CAD drawings for once we have the pre-production versions of those in hand.

As for the 16g install, we have a car here courtesy of Nixlimited that is getting that setup. Stay tuned for results on that.

The intercooler setup on the red Z was necessary to clear the hood latch support brackets the Z has. The G37 doesn't have those support brackets and can therefore support the intercooler version you saw in the CAD drawings and layout pictures without modification. That said, we developed new hood latch support braces that gives us an additional 2" of clearance so we can run the same intercoolers on both the G37 and 370Z while supporting the hood latch properly. In addition, the extra clearance allows us to run a wider, taller core on the 370Z than what the red Z currently has. The red Z currently has 10" x 10" x 3" intercooler cores while the production cores with the new support braces are 12" x 12" x 3" cores. Also, the new end-tanks are going to be polished, cast aluminum tanks as opposed to the sheet metal prototype end tanks you see in the pictures of the red Z.

Here is a picture of the support bracket I'm talking about:


As far as CARB approval on this kit goes, we will be going after that as soon as we're finished with CARB approval on the 370Z Supercharger kit.

Yes, that shouldn't be an issue and people have installed our Garrett based turbo kits in their garages on jack stands.
