Default Two wastegate ?

Do I need 2 wastegates for a Single turbo setup if I can't get 1 near the merge of the exhaust at the turbo? Like this? (Not my setup)

If you want to control boost properly, then yes. If your pipes merge before the turbo, put it in the merge. If they do not merge before the turbo, you should use 2 wastegates.

I would. I run two and boost is controlled solid.

You could one run off of a single bank. I've also done that in the past, but depending on your power level, some swear that it will make the engine wear unevenly between banks.

Thanks for the info, I will make sure to get 2 if I can't get one at the merge!

You can run one wastegate in a setup like the one you pictured. You'll need a pipe coming off of each side of the outside, merging into a wastegate flange.

Someone here ran a setup with the hotside almost identical to the one you pictured, and ran a single wastegate that had a small tube coming off of each bank and merging right next to the turbo. With a 60mm gate he was able to control boost really well.

Pretty badly placed wastegates in that picture. Looks like they have room to put there where they need to be too. Makes no sense.
