Rays_240

Im looking for a bit of help / experience.

I have and sr20 and i have swaped on the z33 / 350z transmission in a s13. The trans works great as far as shifting and taking a beating. However im having problems with severe noise and vibrations. Im looking to see if others are getting the same noise, particularly with a twin disc as im not sure if the noise is being created by harmics between the clutch/ flywheel and trans. The noise is very loud and sounds like when you have the car in to low of a gear and you try to accelerate, sort of a gear chatter noise. It happens when accelerating at 3k and below and also during decel at around 3k and below. The vibration follows the noise but is also steady without the noise and is particularly bad around 3k. Along with vibrating the car it also vibrates the shifter. So bad that ive just about bruised my hand after a long drive.

The car has nismo mounts and the stock 350z trans mont. I had a solid trans mount but i took it out because i thought it was causing the noise.
