Flywheel discovery M30 - M10 trans related

[Gunni]

I was pulling a B20 flywheel from a engine, and yesterday I was pulling a m10 flywheel from a B18 engine,

I was looking at them and they are identical in size in regards to diameter and ring gear diameter
the only diffrence is the mounting points for the 218mm pressure plate are a little closer to the center then the B20 one, wich is on the edge really,

This means that if the 228mm plate fits inside the M10 trans that any BMW 228mm setup will work, that means all 325i setups as well,

Just another option if a M30 trans isn´t available,

So a m10 gearbox will work a m30 engine ??

allows you to use a standard m10 prop as well iirc

I´m not sure on the prob, but I used a M20B20 one,

[Brianmoooore]

Prop lengths are shown on the ETK, and, I think, on realOEM as well.
