What wastegate flange does the B-series SFP mani come with, I have tried calling them the past few days without any success. I want to get in on Viren's GB, but if the flange is for a HKS wastegate, I may as well just look for one of those. THanks,

 

they will make it with whatever you want - 35, 40, 46 etc.

 

Yup, Tial/Deltagate type flange or HKS style. You just specify what you want.
