I really want to upgrade my manifold to a turbo manifold. I have looked on some sites but all the turbo manifolds say "fits all Audi 1.8T compatible with T25/T28 T3/T4". What does T25/T28 T3/T4 mean? Will this fit in my TT?

Thanks

 

ATPTurbo.com has an exhaust manifold for our car which has a transverse 1.8t engine. I am going to get one when I upgrade my turbo to the GT2X, when they come out for our car. If you get the manilod then you should go with the full performance exhaust too at the same time. You will feel a difference. And chip it to.

 

Those are the types of turbo intakes it will fit

Mostly Garret Brands

T3 - Link
T28 - Link

Our turbos are KKK series unless you upgrade to those turbos its not a direct fit. Though it will fit our engine just not the turbo.

 

So I am guessing that a K03 for the 1.8T has a T03 intake? Im hoping that going to the high flow manifold will give me some good flow for the GT2X, if they ever come out with it for the transverse engines.
