Wastegate flange
Thanks Nick W
they dont have an adapters that i know of ( i work a lot with turbo systems)
if you have a hks 40MM gate style flange, hit up ATPturbo.com and get the 4 bolt to 38MM adapter, its a plate with countersunk holes and a 2 bolt tapped that allowed you to retrofit.
My biggest suggestion, cut off the old flange, weld on a new one.
