What Quality Hi-Output Alternator Options Are There?

How has it been holding up?

Awesome. No problems at all. 80,000 miles on it so far. Installed them in my tacoma's as well.

Big three?

I think my alternator is on the way out so I'm looking to upgrade not just replace it. I saw a couple mentions of "big 3 upgrade" but searching for that hasn't gotten me anywhere. Pretty sure I get the idea but I would love to have a guide to follow and some pictures to help along the way.

Here's links to a couple of topics on the "Big 3" upgrade, first one is referring too doing it on 4th Gens, the other/better one is referring too doing it on 3rd Gens and also covers a fuse box install and a power inverter...but it's the same "Big 3" upgrade on either.

I seem to recall a plug & play Supra Alternator thread when I bought my 2007 SE. Might have been a small upgrade for stereos.
