tried looking on the wiki...
i've fitted a m50 with a m20 flywheel and used a 318 is e30 box.
seems i can't turn the engine over with no plugs in..
i', sure i read that with the combo i have i have to either lighten the fly wheel or cut down some bolts to stop them hitting the back of the fly wheel..
can anyone tell me which bolts these are please?
m50 with m20 fly help

as you bolt the flywheel on youll see it.
at the join between the sump and the block there are some long bolts and a bit of the sump that needs removing.
im sure someone will be along with a photo

I've done it, but its a fairly large ball ache, that was with two of us on a 4 post ramp. You'll need to drop the subframe an inch or two for clearance, and the starter needs to come off again, I would definitely consider just taking the lot out if I was doing it again.
It will either be catching on the block where the long rear sump bolts come home, or the bolts that hold the flywheel onto the crank will be too long.

Suggest you take the advice offered here - while it's out get the flywheel lightened (local engineering shop should do it for about £20). Solves the sump problem and spins the engine up quicker. Worth doing (i've done this on my M52 conversion)
Mine was on an M50 block so it might be different but it was the raised bit on the back side of the block they screwed into that caught rather than the bolts themselves, I just ground a few mm off.lee wrote:when looking up from the underside its the 2 bolts located up behind the flywheel...these look to be on contact with the flywheel... out it comes then!
Not sure why it would have caused you issues going uphill, but as it was on a different engine I wouldn't expect it to be the same.lee wrote:yeah i will do.. had a lightened flywheel before but hate it, due to being on a smaller engine. removed about 2 kg... hated it having no power up hill...
what have you had removed from yours?
I'm not sure how much was removed (stupidly didn't weigh it before installing it into the car), but I had it taken down to the obvious/natural step on the engine side as advised by others on here. Removes a decent amount, but doesn't exactly make it featherweight!
