B-Man looking at your pics it appears to be identical to my std garret 3040 or whatever people call them part no SB8006, the wheels are the same size and profile, the comp housing is the same, mine is using a 0.82 exh housing so its a bit hard to compare, but if anything thats the only difference, the shape of the exhause housing. what power are you making with that thing with what boost and other mods, cheers clint
