Your standard box is stronger.

Any chance you can tell us more about what you're trying to do here? It seems you're a little mixed up on the box types.

The PPG 1-4 gearkits are designed for the five speed 752/754 case gearboxes and not the 6MT you should have in your car - and they're sold primarily to overcome the durability issues encountered when running a lot of torque through the five speed box.

The 6MT you have is much stronger to start with and so there's less need for aftermarket replacements. Even then, think the only gearkit PPG offer for that case is the full international Group N 5sp dog engagement one.

Do you have a five speed box in your car for some reason, or..?

 

Yup its a dog box and steven darley has had loads of problems with his in the yellow car.
