Newb engine code question

[Nygdup]

I've learned a lot during my month of trolling these boards. I now know that my 318i has the m10 motor. What I haven't been able to figure out is what specific engine codes correspond to certain models.

For example, everyone talks about a "s50" swap. Where is that motor normally found?
