Is it the same alternator on all E36s or are there different ones for the different engine sizes?

Any ideas on how much I'm looking at for a new one?

Different ones, Valeo and Bosch, also different Amperage ones. http://www.realoem.com/bmw/partgrp.do?model=BF32&mospid=47430&hg=12&fg=22

Cars with air con usually need a higher rated unit
