this is on my list as well. between the lightweight flywheel i already have, the underdrive pulleys i have but have not installed yet, and on the lookout for a cf or aluminum driveshaft it should be pretty snappy. the gears will be the icing on the cake. then weight will start coming off.

 

Before you get a tune consider getting a complete cat-back exhaust system, headers and muffler do not make an efficient system! Differential gears will make a major difference in your quest to destroy the Z!

Another thing not mentioned here is camshafts. Not quite a bolt on anymore but can usually net you some great gains. Of course, you're gonna have to go back to the fact that your car needs some dyno time to put out all its potential power.

Or just rip out all the seats and liner to get to the 350z weight.
