I got my t04s and a tial 38mm wastegate and am not sure which manifold to go with. Originally i was going to have a custom manifold made but am trying to see if anyone has used the xs engineering manifold with a tial wastegate. Seems like the flange on the manifold is square and the wastegate is the oval shape but im not sure if there is some way of using it with a different flange or something. Problem is the xs manifold is cast so you cant really cut it off and weld something else on. Has anyone used a tial wastegate on their single conversion and what manifold was used.
