<-- back to Toyota 5-speed
Can't find a good Datsun gearbox? Toyota K gearbox is the K40 4-speed and K50 5-speed light/medium-duty transmissions found in Toyota Corollas and Starlets. It is readily available. It is good for up to 103 ft. lb. torque, so appropriate for a naturally aspirated A engine. Not strong enough for a turbo or supercharged engine.
