m52 vs s52 flywheels

[IraSummers]

What is the diffrence between the 328i m52 flywheel and the m3 s52 flywheel? REALOEM shows them as diffrent part numbers... Anyone?

I'd ask in the FI section....

why is that?

GG//M3, thanks for the tip. They answered my question. I wanted to fill this in for when someone does a search. I hate searching and finding so many posts that never were answered.

The s52 pressure plate is much more diffrent then the m52s pressure plate, so the two cannot be interchanged (mabie with ALOT of work, but you can pick one up for arround $100). The s50 will not interchange with either as it is a diffrent size then the m/s52 engines. It could work if you use the 328 clutch pack, but not as stong as the m3.

Just to clairify, you can swap the S50 and S52 flywheels. I'm running an S52 flywheel in my 95.

Thanks for adding to it. I think it can also work in reverse, but the s52 is larger. From what I understand, the crank side all fit, it's just which clutch pack you use.

Do you have a s52 or s50 pressure plate?

Ok to clarify all the M/S 50/52 flywheels are interchangeable. Only thing is if you put an M3 flywheel on a 3 series you also have to use the M3 clutch thats it. S 50/52 flywheels accommodate for a larger diameter clutch

bingo, all s50/s52 flywheel/pressure plates have the same hole patterns.

For the crank...not the presure plate...right...

Yes for the pressure plate too same bolt pattern. We are talking s50/552 only. Obviously the M and S flywheels will have different pressure plate bolt patterns due to the smaller clutch.
Why don't you post what are you trying to accomplish and we will tell you what you need.

Hey I have an m52b28 and at the moment it's auto but going into a manual car with a getrag in it, I spoke to dkm about a twin plate 240mm set up but they say it's only for m3, I thought they are the same, any help? Il be using there flywheel pressure plate and clutch.
