Transmission swap...Grinding noise when engine braking??? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Just did an auto to manual swap. Everytime I let the car engine brake (car in gear foot off the gas) and im in the 2300-2800rpm range I get a kind of grinding sound along with some roughness.... it sounds kind of like the driveshaft being pushed too far into the transmission.

Ive got an ebay lightweight flywheel, RPS 6 puck street clutch, stock driveshaft and poly filled engine mounts o and I used a needle bearing for the pilot bushing.

It also chatter s quite a bit when in reverse or if im turning and trying to engage the clutch. Will the clutch wear in and quit making the noise so apparent?

Anybody else have this prob?

Thx
