Wastegate size
#1
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

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)
