Correction-
According to the parts fiche from http://www.villagetoyotaparts.com/products/TOYOTA/2004/4Runner4000CC-24-VALVE-DOHC-EFI--AUTOMATIC--5-SPEEDSR-5/ALTERNATOR-ASSY/8644741/270603102184.html Its 130Amps.
What do you need it for?

1560 watts so at 12 volts figure about 130 amps.

Thanks.
Im adding: ~1500 Amp/sub. And ARB Fridge, if it can handle. Will likely do Big 3 upgrade and do a massive upgrade on my single battery. Didnt want to have to add second battery or do alternatory swap.

FYI - Replied in yor other thread - I'll re-post here:
Don't know off hand - but noticed your initial post was in the "Audio & Electronics" section and not a gen specific forum. Is this for an audio system by chance?
If so: Just an FYI - I ran my '99 Tacoma's 70-Amp Alternator on a Rockford T20001BD (2000+ watts RMS) + JL 450/4 (450+ Watts RMS) + Sony XM5026 (100+ Watts RMS) for close to a decade, and never had any alternator/battery issues (replaced the stock alt once in 11+ years). I did use good batteries (Optima, Oddyssey, etc), but that combined with sensible listening habits did the trick.
I'm currently at 3600 Watts RMS in my new '13 T4R, and the factory 130-amp alternator is doing just fine. Also had 2000+ Watts RMS in my '87 4Runner, and its factory alternator also held up to the overall current demands (and I was a young punk back then! )...
If this is for lights and other "constant draw" ancillary accessories - then you might have more to worry about IMO (butt-loads of auxiliary lights, high duty-cycle winching, etc). But audio systems of multiple-thousand-watts RMS can easily be sustained off the stock Toyota alternator if enjoyed within their non-clipped extremes IMNSHO...
Also - I know in the 5th Gen's, you can fit a Diehard Group 31M battery in the stock location (same as an Odyssey PC2150 - a $450 battery!). I'm completely happy with this single battery and my 3600Watt RMS system. I'm not sure if a batery that large will fit in a 4th gen - but the Diehard Platinums are the shiznit (They are AGM batteries just like Odyssey/Optima/Kinetik, etc).
