Hey guys bare with me this is my first build I only want to do it once I purchased a t3 silver bullet 66/74/74 with a .80 exhaust housing I was told that would be a great turbo to stack a s480 on but now im tore between getting the t4 66/74/14 with a .91 exhaust housing industrial said go with the .80 t3 because it would spool quicker with the s480 any suggestions also thanks in advance.
