M3 Chugging--Fix

["Tim Gergen" <m3gizmo@xxxxxxxxxxx>]

I have a 95 M3 that has been "chugging" for the past six 
months...Although it was not violent, you could feel the motor 
"chugging" between 2-5k rpm or so.  Two dealers and 2.5 weeks worth of 
R&R could not solve the problem.  The dealers claimed there was nothing 
wrong with the car, although that is not what they said when I would 
drop it off..."yeah, there is a problem" they would say after listening 
and sitting in it...At any rate..problem SOLVED...Turns out my flywheel 
was shot.. Apparently the dual mass flywheel takes a bit of punishment 
from drivers like me...Usually, the clutch has springs in it to soften 
contact..However, as many of you know, the dual mass flywheel was BMW's 
way (in the M3) to build someting really expensive to circumvent 
something that worked fine in the first place...At any rate (again), I 
am doing a retro-fit project,, Seems taht a 525 flywheel is a lot 
lighter and is NOT dual mass..With the change of a ring gear I think I 
can convert to a lighter flywheel, a more cheaper flywheel, and a 
"normal" cluthc..Also use a 96 M3 pressure plate at the same time to 
tighen it up a bit as the turbo will go in this weekend or next.  i will 
let you all kno how it goes..May be a cheap performance upgrade.....We 
will see..R&D will tell.. Tim
