What kind of car are you gonna swap it into? If it's a 5G civic with OBD-1, you need a HYDRAULIC operated tranny, not the cable type that comes with OBD-0. Also, it makes wiring it up MUCH easier... Also, do u really want ultra short gearing? My friend has a 92 civic hatch w/a B16A2 (170hp), and he'd rather have my tranny (GSR) cause it's gears are a little longer, not so short like his. Yes, it could help under acceleration, but you have top shift more and possibly use the clutch more. Another thing, those cable operated trannys are not as good as the rod-actuated hydraulic trannys.
Hope this helps,
Mike
