beacause the type r tranny uses hydraulic fluid to move the throwout bearing and the 93 tranny uses a cable...
think of it this way...
on a bike, when u hit the brake lever, it uses a cable to activate the brakes but on a car, when u hit the brakes, it doesnt use a cable to tighten the calipers, it uses hydraulic fluid to push and pull "pistons" to get the same effect.
