Alternator upgrade to 88-4R?
well, I've killed another alternator. This makes number 2. (60 amp weakling.) I seem to recall that there are beefier alternators that will fit without modification. Could someone point them out for me? [88-4R 2.4L NA]

I have a 140A I got from LCE, it's a direct bolt-in and works great in my 87
I think it's AC delco internals

I did have to get a slightly smaller belt to fit the pulley on it, the pulley is a tad smaller than stock FYI

Wow that cost just a little bit.
Marlincrawler, Yotamasters, LCEngineering, I don't remember which one it was but they have a bracket kit that allows you to use a GM alternator. I believe they said only minor wiring mods were needed. The right Cadillac alternator can put out some good amps.

I was hoping to avoid having to install new brackets or plunk down a lot of coin for a replacement alternator. But the 60A denso and clones don't hold up very well. It seems they are too small to service the truck's demands.

I hear ya man. If you're going to add a killer stereo, high wattage lights or other stuff (I assume you have) that creats more demand you're going to have to supply it somehow. Obviously the stockers aren't working so hot for you so you need to go a little out of the box to feed it.
If you haven't installed power hungry stuff, well, you have a problem.

The truck is pretty much stock. No monster stereos or big light racks. Just a couple of driving lights that don't get used very often. The problem seems to be that the rotor windings are undersized. I opened the alternator and the rotor windings are fried. Same thing that happened the last time.

How old is your battery? Maybe it isn't holding charge like it should and overworking your alt.
Or perhaps you have a short, or a bad ground causing things to fail faster than they should? Or maybe something leaking onto the alternator?

Battery is fairly new and it started just fine, so it wasn't a low battery. AFAIK, this particular alternator has a reputation for failing.

jennygirl makes some good points.
Perhaps you've had internal regulators that were about to go out in your replacements, or if you've been rebuilding one perhaps you've been reusing a regulator in the same shape.
If that doesn't cut it maybe try thicker main power and grounds.
I've only used 60 amp alternators on my muscle cars. On paper the stock wiring in great shape should be more than adequate for them but after years of usage and heat soaking creates resistance. I always upgraded the stock V8 main power and grounds to 00 gauge. The motors crank faster, the lights are brighter at idle and the wipers operate a little better too. I'll probably upgrade my truck to 1 awg or 1/0 awg for those very reasons.
If it's none of those then it sounds like I better start exploring my options as well.

If your not running a bunch of high current loads .
Are you getting China brand junk rebuilds ??
I think you have something else going on.
Now granted all my Toyota`s get the big 3 upgrade I seem to have good luck with starters and alternators and my driving style is brutal .
Drive about 10 miles with 6 or more starting and stopping of the engine.

I have a 120 amp on my 85 Celica with 22re. Only thing I had to do was pull the bushing insert and change pulleys. It was from a 94 Jaguar with the inline 6. Think xj6 or similar?
