I picked up an S54 a while back and I'm in the process of accumulating parts for a swap. In fact, I'm still hunting for the right chassis to put it in, but that is another topic in itself.
I decided on the ZF 320Z for the trans since they are abundant and I can source one locally for dirt cheap, plus they are reliable, smooth shifting, etc. Basically all the reasons why everyone loves the ZF. I'm trying to figure out what is the best clutch setup for me though.
The S54 I bought did not come with a clutch, flywheel or pressure plate, so everything is open ended. I've done my homework and I know that various combos will work work well. I'm just looking for some opinions on which would be best. I'm trying to keep things affordable by using stock BMW/OEM parts so I'm not really looking for a fancy lightweight flywheel, however I'm open to ideas. I own an E46 M3 as well and I think it would be nice to shed a bit of weight from the stock flywheel while keeping chatter to a minimum, so if there is a way to do that using other OEM parts that would be awesome. The car will be a weekend/backroads/track car but I'd like to maintain reasonable drivability for the nice days that I want to drive it to work in the summer. Here are some of the combos I've been considering.
1. E46 M3 dual mass FW, E36 S52 clutch and pressure plate
Pros: One of the cheapest options, great drivability
Cons: Heavy FW. Would be nice to lose a bit of weight
Questions: Is this combo possible or does the E46 M3 flywheel require an E46 M3 pressure plate
2. E36 M3 S52 dual mass flywheel, E36 S52 clutch and pressure plate
Pros: Same as above
Cons: Still dual mass FW
Questions: Is the E36 M3 flywheel any lighter than the E46 M3 flywheel?
3. E34 M5 Clutch Disk w/ E36 M3 FW and E36 M3 Pressure plate
Pros: From what I have read the sprung hub makes the clutch more friendly with lighter flywheels.
Cons: Setup will likely cost a bit more since it would need to be pieced together.
4. E34 M5 Clutch disk w/ single mass steel flywheel
Pros: Possibly the lightest flywheel using OEM parts
Cons: Possible chatter.
Questions: What is the consensus on this setup. Does the sprung hub clutch actually make a single mass flywheel tolerable with the S54? Which single mass flywheels and pressure plates would work with this combo?
Any input on the topic would be appreciated. Thanks!
