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

the smaller the WG the higher the boost, so get oversize if you dont know

I would use something in the area of 50mm.



Wit a small hot side, a large gate is needed for exhaust flow. Keep the gate divided from the down pipe.



Larger turbos can afford smaller gates with moderate boost (10-14 psi)
