Im trying to decide what to do as far as a tb goes. I dont feel its necessary to get rid of the oem tb if its the same size as the inlet manifold on the supercharger. I dont feel I would bore out the manifold so I am trying to save some cash . I dont want to spend 400 + on a 70 mm tb if it does not match. Plus the oem does not seem to be that restrictive.
