[QUOTE="V-Man, post: 575625, member: 2609"] After reading some precious info and advise from the gurus... am waiting for the kucing to come back to me on some calculations :) My findings: - Both m20 single mass and m50 double mass has the same diameter 228mm - Both M52 328i and M3 has 240mm on the flywheel. - Stock dual mass flywheel = ~11 KG (just the flywheel) - M20 flywheel (single mass) = ~7 KG (just the flywheel) - m20 clutch kits are cheaper compared to M50 kits (pressure plate, clutch etc) - M20 starter motor (the M50 starter will not mesh with an M20 flywheel) - E21 323i release bearing (30mm height) - M20 flywheel bolts as the M50 items are too long (new pressure plate bolts too) - M20 flywheel machined to fit the M52. This involves removing a minimum of 4mm up to 10mm - Single mass gear rattle at idle. This was probably my biggest concern about it but the perks are more fun to have :) [/QUOTE]
