Here's something I found the other day.

 

The 90A stock Maxima alternator is enough for me, but for those of you intent on turning your car into a monster boom box, lighting the world, or just burning up your wiring:

Pricey, perhaps, but it would bolt right in - I've got the 90A Maxima alternators on 2 - SPFI EA82s (one inboard and one outboard). One of the easier upgrades I've done - well, except for having to make a .300 pulley spacer (actually anything from about .290 to .320 works).

I dont mind the price, if these things are reliable, then if mine goes out. I might slap one in. Who knows... If this thing ever gets on the street again, it might be due for some RA lighting on the bumper and roof rack for off road usage. Great post.
