Hey all,
I have a GT35R (gt35/40) ready to bolt onto my engine in my fc. Im thinking of using a trust manifold to suit the turbo which has fairly short runners on it, engine is in very good condition, believe it to be a mildport.

Question is, what size external wastegate have people run with these turbos? i've heard from 38mm to 48mm. looking at running between 10psi and 16psi

Thanks
Andrew

 

Buy the biggest thing you can afford.

I would only use these:
Tial 46mm
HKS Race 50mm
HKS GT / GT II in 50mm or 60mm size

Ted do u think a Tial 44mm would work ok? lookin to run around 16lbs on a big streetported motor and a big (mitsubishi (greddy) tf07 turbo.

 

i run 15 psi on 60-1 with a standard hks wastegte, no problems at all..

I got a Tial 50mm... Seems big enough...
