What are limitations of the RB25 Transmission? horsepower wise as well as torque wise, and after reaching it's limits what can be done to strenthen it?

I dont know any numbers off hand but the R33 Rb25 mt is based on the GTR mt. Also I have yet to see one drop... but a friend has one in his R31 and its synchronizers are going. He was running a 2.2 with a little IHI rx6 up to 1.7 kilo so the mission was getting its *** kicked just about every day. As far as making it stronger call in the cross or call in the DOG!!!

they quote 6-700 hp for the rb25 trans mission is this enough?if not there ae plenty of other option I even know of one guy who used a supra box for something differentmeggala
