Interchangeable parts?

There no such thing.

the only bmw 6's i know of that are interchangable are m50,m52,s50,s52.

there arent any 24v head swaps for an m20.




your basically limited to FI on your m20 if you wanna make 340. other than that, you need to do a swap.

this is a helpful post. thank you for contributing to the discussion.

doing a m50 swap will take the same time that a head swap will

or not much more

OP: the 'family' code in BMW engines is the second digit (ie, the 5 in m50/m52).
