los, dont go for the LSD tranny, dont mean to bash on your sale racer, but for los the LSD tranny's on honda's will break very easily. Its note even worth spending the extra 300 or so normal for the optional LSD tranny. but that is a good price for the h22 complete swap. So go for it w/o the LSD, trust me bro, mines broke and i only spin 1 wheel.
