when connecting the wastegate to the manifold the bolts that are provided have threads on both sides. But one side of the bolts have more threads. Does the side with more threads go into the manifold or the side with less into mani? or visa versa. help me out asap thanks

 

personally i have bad luck with studs i would change to grade 8 bolts.. but thats me. unless u cant get up in there or someting.

 

the studs you are referring to are just the normal tial 40mm installation studs. Thread the short end into the wastegate flange, and save the long threaded portion for the nuts.

 

Thanks
