I have same chattering noise but I beleieve I have standart flywheel (I have Euro 3.2, do they have lighter flywheel?). The sound only appearing when the engine is warm (oil temperature is at 90,not water temperature) and it disappears when I depress the clutch. I've been told that because of latter, that means that the front input beraing of the gearbox is going south. Is it true?

The lightweight flywheel reduces the ability to damp vibrations in the drive-train from the motor oscillating . As a result, the gears in the transmission will rattle some (most noticeable at idle in neutral when the clutch is engaged). The rattle is primarily dependant on the flywheel, the transmission oil and the engine rpms. When you engage the air conditioning, the rpms are increased by the DME to offset the increased load on the engine (end result is to maintain or increase the rpms at idle). If the result is higher rpms, the gear rattle is reduced, if the car bogs some (rpms drop), the rattle will be more prominent. In addition, there is an additional load on the engine when the air conditioning is engaged which can help to damp some of the oscillation in the motor (which would reduce the gear rattle). Every car is a little different. Your DME tuning can come into play as well. Regards, Rich

When they start making noise. :-) Although, since you'll have everything removed already, might as well change them now. Especially if they're still original. Jim Bassett

My car doesn't have it. There's no door or > cover or anything. No port whatsoever. OK, that's pretty strange. Not only should your car, which you say is a 96, have a standard OBD-II port, but I'm pretty sure that by law it's required to. (The BMW proprietary diagnostic port in the engine compartment doesn't count.) OBD-II was required starting in 96. There was a gap in M3 production until about May 96, when my car was made, supposedly because BMW wasn't quite ready with the OBD-II compliant model. Your car sounds more like a Euro car, which has the round diagnostic port but no OBD-II capability. Any possibility that a PO has replaced the under-dash panel with a pre-OBD-II version and stuffed the connector up into the wiring rat's nest under the dash? Neil 96 M3 - With OBD-II port

But there is no way > I'd drive something that low on the street. I have a 3.73, since mine's primarily a track car, plus the 6-speed for driving there at reasonable rpm. It's a nice combination, but not inexpensive to do. You have to really want to do it to satisfy your own vision of what the car should be. Personally I think that a 3.38 swap isn't worth the trouble, effort or expense. Here's a calculated rpm table (rounded to the nearest 50 rpm) for 75 mph cruising in 5th and 6th gears, using Toyo RA-1 tires with 852 revs/mile. Diff 75 mph Ratio 5th 6th Note ===== ==== ==== ================== 3.15 3350 2800 Stock 95 M3 ratio 3.23 3450 2850 Stock 96+ M3 ratio 3.38 3600 3000 3.46 3700 3075 3.64 3900 3200 3.73 3950 3300 For performance street use I'd think that 3.46 would be worthwhile but still just about tolerable for a 5 spd if you don't drive long distances too often, and terrific with a 6-spd. For track use I find my 3.73 is a hair short geared (although of course that depends on where you drive) and suspect the all round ideal might be 3.64. Unfortunately, the donor cars for that ratio in a 188 gearset with LSD are rarer and therefore more expensive than for the 3.73. It's also worth pointing out the the shorter ratios make smooth shifts harder to achieve in street driving. on 9/24/07 3:08 PM, "Gary" <probikeguy@probikeusa.com> wrote: > The six speed box shifts WAY better than the five speed. I was completely > shocked at how much better it feels. That's odd. I was warned beforehand that the 6-speed would have a heavier shift action, and mine certainly does. E36 M3 reviews I've read in European magazines also point that out, in one case even suggesting that the 286 hp 3.0 litre model was a better used car buy because of its nicer gearbox.
