rear diff, front diff, sump pan to take front driveshaft, cv joints, all that sort of stuff is the same as what the gtr has
im not sure about the gearbox whether its a rb26 gearbox or a nissan modified rb25 gearbox
essentially your car is kinda the gtr's younger sibling - the handling characteristics of a gtr, but not the power
apart from that , i cant tell you much more - cause this is as much as i no!!
hopefully some other guys will tell u more soon
