M20 Clutch/SMF Conversion on M52

Post Fri Feb 01, 2013 1:20 pm

I already have a lightened M20 flywheel, starter motor and new sachs clutch. My question is, what parts do I need to order off these diagrams to complete the assembly? Bear in mind I don't have any flywheel bolts etc as my car was not an M20 to begin with. Cheers!

presuming you have a full clutch kit, so you need nothing else, your bolts from the new will be fine,
if you don't have a release bearing i'd invest in an e21 323i one as these are self lubricating.

Superb, thanks bud. Not cheap though are they! Sounds worth the investment though.

it real is worth the investment,
and compared to the price of a billet flywheel i think its a pretty cheap mod.

You need 10, 12 and 7, make sure they are M20 flywheel bolts as M50 are longer.

Self lubricating? They are the same as E30 release bearings but just a little taller

Noticed the E30 flywheel bolts are listed as 'ended' - but they are M12x1.5 28mm? I noticed a lot of the newer automatics use the same 28mm flywheel bolt - this is fine to use right?

10 being the spacer Dan?

Cheers!

In that case they have probably changed the part number for the bolts, and as you say are the same as the newer

Spacer yes, its more of a washer and just sits underneath the bolts

Cheers bud. I'll be in touch soon about exhaust manifolds and p/s pipes too.
