what size external wastegate
 

full bridgeported s5 13bt with gt37 masterpower turbo. im only gonna run 10psi. what size wastegate do i need? 38mm, 40mm, 44mm, 50mm...

really? no one cares?

Go the biggest you can fit...

Better to flow heaps of gas, than to get boost creep because your gate can't control things.

Post pics of the manifold you are using. You need good wastegate positioning and the correct flange. What exhaust are you running?

i like how you waited a whole 15 minutes for someone to give you a definitive answer.

arghx has a good point. what flange is your manifold set up for?

i was gonna get the manifold made from steam pipe and flanges to suit what i decide on.

im impatient and no one had even looked at the thread. haha
