I replaced the (most likely original) alternator in Sept 2010 with the 94Q, having 220k miles at the time. I do recall some intermittent strangeness with the display (TCS warning lights or something) for a few weeks prior to it not starting. It wasn't the most fun job and it's probably a good idea to disconnect the battery so as to not scare the crap out of one self when the positive wire rubs against some metal. Replaced with one from IOS ($270 with $35 core return) and she's been fine since...
