Yeah its been done. Basically just cut a hole somewhere on the manifold, weld on a flange. Connect

I personaly did this and i welded the internal wastegate shut on my 2871r. all you have to do is make sure you mount the wastegate where all the runners meet on the manifold and make sure you dont you dont put it on a single runner or it will cause lean conditions on that runners cylinder. I actualy still have my manifold pre-made if your looking to purchase one? pm me if interested.
