The flywheel itself will cause slightly faster revving under load (it still has to propel a 3500lb car) and under no load, it should rev much faster. You will lose some of the momentum the flywheel carries with the reduced mass so it will be harder to start from a stop. But shifting will be smoother and rev-match downshifts will be easier since you can be off to a certain degree more in RPMs and not jerk the car as hard. The engine should also provide more engine braking and when you push in the clutch from higher RPM's, the revs will drop faster.

Yeah, you must have read my other thread regarding this in another area here on the site. Yeah, seems Zimbo experienced the same.

No I missed that one... It's actually a very common problem that everyone on my350z.com mentions. I was hoping that it wasn't that bad since I have to drive the kids around almost every afternoon. How intrusive is the sound?

like rock grinder. I can't imagine that it don't cause damage.

The rattling sound is normal. And actually, if you listen to a stock 6MT closely, you'll hear the rattling very lightly when you shut the engine off. Our trannies are apparently very noisy. The Dual Mass Flywheel that comes stock helps absorb this noise since the flywheel itself incorporates 2 pieces that are sprung. It takes the place of a clutch disc with a spung hub. My speculation is a dual-mass flywheel is more effective at controlling these noises. And seeing as how our trannies are inherently noisy, Nissan/Infiniti chose to use a dual-mass flywheel instead of a sprung hib clutch disc. Keep in mind At least some Porsches and MKIV Supras use a dual-mass flywheel. I know for a fact that Supras exhibit the same noise. I've heard of no consistent problems with the Supra 6-speeds nor any problems related to this noise. In fact the Supra 6-speed is known for it's overall strength. In either case, the non-dual-mass flywheel is going to increase the noise level. Hopefully you used a clutrch disc with a sprung hub which should help a bit, but I do believe Nissan used the dual-mass unit for a very good reason.

Yeah, the only thing keeping our stockers from sounding like that is a huge, heavy rubber dampener. David, give me a call...310.818.1875
