S14 Crankshaft into M10 Block, What does it take?

[Amoxin]

Hi there, I searched on this one for over an hour, so I'm sorry if this topic has been discussed before.
I'm wanting to know what is required to put the S14 crankshaft into the M10 block. I have heard of the nose on the S14 crankshaft requiring modification to make it fit in the M10 block, but I am quite clueless past that. Any information regarding this would be awesome.

Thanks in advance.
