Looks like it to me with the compressor side of a ta49 has larger compressor inlet and wheel,also the ta49 has equal length compressor blades and the stock one has tall and shorter ..I think the opening on the inlet is 2'' on a stocker w/ no lip on the inside. The 49 is like 2 1/4 '' and is smooth no ridge on the inlet . gnttype.org
