Of course not, its cheaper then having to replace complete gearsets when you destroy them though. If you are buying one of these types of boxes new, I am sure you can spec your own gear ratios. I have seen sequential type boxes uses for FWD 3SGE's. They are an off the shelf item. They do a gearset rated at 600nm, which is enough for most (perhaps not for my wayward goals). Will have to look them up again, I cant remember the manufacturer at this point. I think they may have been swedish or something?
Anyway, I believe this would mate to a 3sgte block. By the time you'd sorted your shafts and shifter mechanism, you would be lucky to get change from 20k. One day maybe.
