Only ATP and Forced Performance have these v-band configurations off the turbine housing itself. Unless you have a casting facility that can create one, making one on your own will be very difficult. Forced performance usually use theirs for the GT-R series. I'm not sure if they sell the housings individually, however.

that appears to be just about the best spot to put a wastegate.

I wonder how the boost creep is with that mani? haha jk that looks awesome and super effective

I have seen a few guys weld a flange straight to ex housing before. Why not just do that?

Welds are typically **** due the differences in the metallurgy. You're taking steel flanging and using against an oxidized iron nickel. Not the best thing in the world to do. If that's all you have then that's one thing, otherwise, there's no real benefit as you'll more than likely develop exhaust leaks from the gaps the rod couldn't fill in.

I have welded and seen plenty of v-bands flanges welded to ex housing without any issues. I dont see why welding a w/g flange would be any different???

It's doable, but you'll always get a weaker joint than welding similar metals..

The wastegate has a lot of weight to it, so the housing + flange has to support a lot of stress and now the strength of the weld is critical.

When you weld a V-band flange on the downpipe, first it's usually a big 3" or 4" flange with lots of surface area.. Secondly, the downpipe is usually supported by brackets, exhaust hangers and that takes some weight off the welded joint.
