GTM Turbo / Manifold question

Chuck33079 · 06-25-2015, 03:56 PM

Are the GTM turbo manifolds the same regardless of what turbo size you go with? For example, is the manifold the same whether you go with the small GT28 or a GT30? Also, are the turbos they use off-the-shelf Garretts? It looked like it, but I'd rather be sure.

First one to derail this into a "GTM sucks fat dong" thread gets a mushroom stamp on their forehead.

Careful I have other cars I can come get you in...just not my Z. Maybe in my wife's Z, if I ask her nicely.

On a note more related to your question, wouldn't it be related to the exhaust housing flange on the turbo? If they are the same size between all the housings then I would think they would be the same, if not then the obvious answer would be they aren't.

Hijacking this a bit since it's manifold related, I'm also curious about whether a different exhaust housing is needed if one were to switch from internal to external wastegates.

True, but I was hoping someone knew offhand. Dammit, this is the370z.com. I should be able to ask a dumb question and have the answer spoon-fed to me.

You should call NNA since people here don't always know what they're saying.

All of the turbo manifolds are the same. They are a t25 compatible housing.

No just different down pipes and wastegate equipment and tubes

Perfect. So any t25 housing turbo out of the Garrett catalog will fit?

Pretty much...
