The stock flywheel is better for drag racing than a lightened one.
For sale is a used Nissan O.E.M flywheel from my manual transmission 1994 300zx twin turbo. It will fit a 90-95 300zx na or twin turbo. It was removed when I first bought the car stock with no mods and had 90,000 miles. This flywheel is in GREAT condition. Perfectly straight, no warping/chipped teeth or raced with/abused. The brown stuff on it is just from sitting in my garage and will come off easily.
New from Nissan it costs $257.66+ shipping. I am asking $85.00 shipped to you. Firm on price. I will only accept money orders or certified cashiers checks. I will only ship in the U.S.A excluding Hawaii. I will ship the same day I receive payment. Email me with any questions.
