what is done to your car?
if its pretty much stock, you might want to look into the nissan key value clutch set. its around 200$. for the entire assy.
throwout bearing, clutch disc, and pressure plate. all nissan parts.
just a suggestion.
my car had cams, but i didnt drag race, and it was awesome for about 30k miles, until i wrecked it. worked great the whole time.
