Opinons on wastegate placement.

Time to mount the wastegate on my home made turbo setup. I bought a PTE 46mm wastegate and would like some opinions on where to mount it. I have an idea, but would love to hear what others have to say. I know there are a pile of turbo systems out there that have the wastegate mounted right into the side of the collector, which is easy, but I am hoping to hold singe digit boost(8-9psi) and I am afraid a wastegate mounted like that will not have the control I want.

Here are a couple pics of what I've got.

I thought it needed to have the wastegate PRIOR to the exhaust flange. Yours is after the exhaust flange. Not sure if that would work. I am curious also.

I've always built my kits with the wg as close to the turbo as possiable . I've haven't had any problems holding 6 psi on any of my junk yard kits . You'll have alot of different opinions that's just what's works for me .

This is what I would do if there's room, hard to tell from the pics. You could also make an outlet on each on the bends before the merge and y them together so the gate is getting priority from both banks.
