Looks like a Tom Nelson Twin to me.... and if so.... he has his TT's made so that they can be symmetrical (or whatever it should be called)... BTW -- NOT saying that you're wrong... cause I really don't know - but that looks like a TNR billet intake etc so was thinking maybe that the turbos are his "new" versions?
i figured they were but like i said, im assuming you just have the housings on there for mockup and the center cartridge will get changed because that wheel is pitched the wrong direction
