gearing is way off for the z32 and the transmission is still very weak (read z33 forums)...pointless for anyone looking to mount this into a z32...maybe someone looking to use this in a custom application i can see the usage but for us z32 the 5spd is perfectly fine since the gearing offers no increase in anything just an extra gear to play with that i think even most track junkies won't use because of the weak 6spd
