E30 Zone

I wonder what is the difference between M30B35 and S38B36 crankshaft. Both have same main bearings, conrod bearings are different but the same dimension, both motors have the same stroke.

What are then the differences and are they exchangable?

Thanks for the info!

There probably is a big difference.

What is the stroke of it?

isnt the m30 a single timing chain and the s38 a duplex?

The stroke is 86mm.

The timing chain sprocket could be different, but it is not a part of the shaft, but can be changed.

Question is why would you want to use one ?

I've got a spare M30 bottom end that i no longer need for £50, it's worth it just for the sump.

If you've got or are thinking of doing a 335 conversion it's handy to keep a spare sump because they are a bit low.

This might be handy for you ?
