ok guy my kit is setup for twin racegates and i might run them but would it be pretty easy to cut the flanges off and add 60mm flanges or would i need to make a new merge?
big time. They will always be a restriction at the pipes leading to the gates. 38mm gates work with 1 1/2 tube. 60mm works with 2 1/2" tube if I remember correctly.
The wastegate positioning is very poor on that setup, your best bet is to relocate the existing wastegate into a position where they will actually flow exhaust gas when the valve opens.
Turbo chicken is correct the wastegate location is not the best. Keep in mind if you size the turbo correctly you will not need much wastegate. Check your back pressure and get it close to one to one.
