Light weight flywheel?

[Shift_Now]

I know the m20 flywheel is a popular mod, but has anyone tried this set up?They say its a direct bolt up, and it looks liek it's probably cheaper than the m20 mod. http://cgi.ebay.com/ebaymotors/F1-ST...spagenameZWD1V

should be better but doubt your 318 will EVER make use of that stage 1 clutch kit invest elsewhere. like a new engine.

huge lack of information on them chromoly flywheels...i'm gonna be testing one in my s52, should arrive friday

[asubimmer]

its too large, 228 is the max that will fit in the getrag 240

i wouldnt trust any ebay brands. if it were a name brand ON ebay then ok maybe, but thered be no warranty. either way i say forget any stage 1/2/3 clutch kit for the m42 and just do the m20 conversion with a ltw flywheel. itd be the best bang for your buck. im doin jb racing 8 pounder with a either an oem sachs kit or spec kit.

I've had this flywheel for about 8000 miles and so far its been great with a oem clutch. I've never driven a stock 318is but I can't imagine having the stock 28lb flywheel.

Hope you enjoy!

hey Guys

I'm thinking of doing the same thing with my 318is m42 rebuild- so I can just find a stock M20 flywheel, and a stock 318is clutch- but do I need the m20 starter pinion?

[gearheadE30]

yes. Or you can just swap in the entire M20 starter. It is a lot easier and probably not that much more expensive.

The wiring is different between the M42 and M20 starters ....and most guys on here would not know how to make the M20 starter work .

Just stick with swapping the pinions or you can even swap the ring gear between the two flywheels .

A little late to the party, but the best upgrade to do is a steel (stock) M20 flywheel and clutch. Have the flywheel lightened to 12 lbs.

The Aluminum ones are expensive and tend to rattle. A lot!
The M20 swap is smooth. You may need to modify your ICV to make it adjustable and smooth out the idle. If you don't know how, Send me one and I will do it for you.

Leave your starter alone and just swap the ring gears out. The M42 ring gear will fit perfectly on the M20 flywheel.

You speak of the ring gear on the flywheel right? How do you take it off?

I ask because I actually chose to do the latter and swap pinion gears and I it was relatively easy and straightforward.

[ash00]

back to the flywheels

How do you remove the outer ring on the flywheel? Those are usually held together with a pin or something right?

[JiXer]

No. They are just pressed on.
Tap it off carefully with a hammer as to not bend or deform it.

A friend of mine (dealer parts guy in CA) sourced a non-AC, non-dual-mass flywheel for a euro M42. It's lighter, and makes the engine spin up nicely. Additionally, you don't need to mess with swapping starters. You really do need to make sure the ICV is in good shape, though.

AKA M40 flywheel. They show up on German and UK ebay every once in a while for dirt cheap.
