Well I've discovered that my flywheel is making some noise. Ive been researching here and have found that there are 3 basic options: OEM dual mass, lightweight aluminum, E28 type.

I dont want to spend $600 for aluminum flywheel and have to rev to 3k RPM to start rolling. The E28 flywheel is a good match for a M30 3.5L crank, but havent found a thread discussing the mating of one to a M20 2.5L crank.

Anyone have any input about this? If it would work, where to get, average prices, clutch arrangements, etc.?

What do you guys think?
