yes it will work.

you will need to weld the flapper shut on your internal WG, and then get a manifold that accepts an external gate

i have greddy cast manifold, will the tial wastegate still work? and is this gonna be pretty hard to do? thanks guys, keep the response coming.

you are going to need to drill a 35mm hole in it and then weld a WG flange to the manifold itself. not the best method, but it can be done
