325is have enuf power for M3 Clutch?

[uber e36]

I have heard problems when people installed an M3 clutch into their 318 because they don't have the power to keep it spinning, and therefor lose rpms between shifts... causing you to engage in the next gear at a low RPM and "bog".

My question... Will this occur with a 325is as well?

Anyone put an M3 Clutch in their 325is?

no its should be ok for the 325.

That whole concept of the clucth droppign fast you have to deal with. My friend just ptu a ACT clutch in his FD3s and it drops hella fast. You just have to be better at shifting.

autotechnica put a m3 clutch in his 318 (I'm 90% sure he did anyways)... he should have some info for ya.

I have the M3 clutch installed on my 318. I never had problems with RPM's falling inbetween shifts. I believe someone else was making that assumption, it definitely was not a problem I've been experiencing. What I did say was that the clutch griped very nicely and that I could even chrip the tires in 4th. I can feel the clutch bite in each gear which actually made acceleration a lot quicker. I just have a much rougher idle and occasionally it would want to stall returning to idle speed. I've heard this is normal with a lighter flywheel, especially after you really heat it up from hard driving. I'm using an M3 single mass flywheel which is significantly lightly than my stock dual mass flywheel which would explain why my engine would want to stall.

Anyways, if you do decide to get this done, get the '96+ pressure plate, and try to find a single mass flywheel, avoid getting anything from '95 M3's. They had the 3.0L early model M3 clutches which weren't all that great. The '96+ pressure plates can take a lot more heat.

325 => M3 clutch is actually a very easy conversion. It was a lot more complicated to make it work with the 318. My mechanic had to do a lot of grinding and modifications. More parts had to be replaced as well.

Thanks Bry!

Well if my flywheel is in good shape, all i'm going to do is put the new clutch in...

But if I have to do the flywheel too, then i'm going to go with the M3 gear...

So 96 M3 clutch + flywheel = zing?

Sounds like a plan for next summer....

I have no idea whether you can just swap the clutch disc and pressure plate, you may need the flywheel as well (not 100% sure). You'll need the Slave cyl, release bearing from the M3. I believe the pilot bearing and release fork are the same.

Make sure if you're buying a use pressure plate and/or flyhweel to have the metal surface sanded and smoothened. Otherwise the clutch disc won't contact properly.

96+ is the way to go, '95 M3 also has the heavier dual mass flywheel which is bad.
