300zx alternators put out what, 75 amps? when they are healthy.
Probably far less than that when they are covered in greasey gunk.

and even less when they have 75K plus miles on them.

Unless there is some z32 magic trick that I don't know about, replacing the alternator on these things is a major pain in the dick.
I had to replace the alternator when I first got the car. we knew it was bad. So I grabbed the one off of my project car and swapped them out.

I'm thinking that one is beginning to die now as well as I can't the voltage to go over 12.4 unless I have the battery on the charger.

With the 240s, you can swap in the Quest alternator and have 110 amps. It doesn't look like that will work on a Z. Not been able to get them side by side to try and compare, but my search hasn't resulted in anything. Its a common thing to do in the z31s. But the closest I've found to swapping out to a better alternator for a Z32 was using the turbo alternator as it puts out a whopping 5 more amps. Woot!
Anyone know of a clever way to make the quest one work?
Know of any other options to look into?

I was doing some research on rebuilding alternators and it doesn't appear that you can rebuild this style. Is that true? I'm assuming that if you could rebuild it, then you could beef it up for a higher output, like they used to do with the older domestic cars.
I just don't want to go through all of the work of swapping it out just to end up wanting more power in a couple of months.
