Wastegates for GT3076R
 

Hi guys,

Recently I bought a used GTM/Gamma stage 2 twin turbo kit with GARRETT GT3076R turbos
Anyway, the missing parts in that kit are the wastegates
Even their's pipes aren't there
So I have two choices:

First, to buy a couple of Tial F41 wastegates and fabricate a pipe for it.

Second, to buy an internal wastegates with their sprockets which is easier and cheaper

Keep in mind that I am looking for 1 bar boost

I really need your help regarding this. What should I do?

External everyday. It makes boost control life so much easier..

Ps 14-15 psi on stock block?

No I ordered all engine parts from Z1 Motorsports and I am waiting for them to arrive
So the engine is built

An external wastegate is an engineer's choice. An internal wastegate is an accountant's choice.

Go external. Internal are a pain in the butt due to boost creap issues.

THIS. I have internals and have boost creep.... you turbos are bigger and you want to run all the way to 1 bar so it probably will not be a problem, but you will have a lot more flexibility in boost control if you go with the externals.

Thanks guys
I think I will go with external wastegates
I already ordered a pair of Tial wastegates
