I am going to try the 316 stainless studs @culberro suggested, nordlocks, squished copper nuts, and resbond. I am also going to order some inconel studs from ebay and get a second manifold/hotside/wastegate set up. We will see which lasts longer.Grinding the wastegate housing is what I am referring to...
Let me see if I can find the PN for the ones I used. They were unequal length on the threads and were perfect, I think the OAL was 55mm maybe? Alternatively, set screws make green studs.

I was just looking at the bay of them yesterday, but now I’m on a work trip for 4 days. I’ll see what I can dig up in my past emails.
And I’m thiiiiiiiiiiiiiiiis close to getting rid of the ultimate wastegate or doing something stupid. Heck, maybe I’ll MIG weld it on!
So far it hasn’t been needed, but the moment another stud breaks off in the housing, zap zap MFer.I have thought about welding. Maybe I will put some tacks around it after I get it bolted up.
I don't normally use gaskets, but I had one so I thought I would get it a try. It spat the wastegate gasket out and it came to rest on the v-band.Also, I never used a gasket between the turbine housing and ATP housing. I did use one between the turbo and manifold....I don't know if they contribute to the problem at all, but I don't think they are needed on a race car if the surfaces are flat.
