It depends....if you don't plan on building a full bore race motor in the next 12 months, I say replace the clutch while you have it out. If it's the latter, run what you have and replce the clutch when you build up the motor. You don't need anything too fancy either. I good brand of clutch and pressure plate will be fine, as opposed to some "tuner" one.


You'll get some debate about Underdrive Pulleys. Most of the Nissans use a weighted one with harmonic balancers. It varies per engine, but the engineers put those things on for a reason. UD's biggest advantage is lower rpms for accesories and it may reduce cavitaion a bit in the water pump. I don't know enough about your motor to give you any advice other than google it and see what folks with you cars are saying about them.
