yes ls and gsr gear ratios if that is what you are asking about.. ls has really long gears.. and i wuld not use a automatic ecu with a stick, i dont think that will be good never heard of anybody doing it, just buy a gsr ecu.. so what have we learned, i think you suld get a b16 transmission, and a gsr ecu, or type r ecu to give you your full potential of the motor
