OK, so I was looking through Napa Online for a new Alternator for my Ram when I decided to check out the prices for the 3g's for my Bronco also. I pulled up the ones listed for a 92 E350 Econoline 300I6 and this one caught my eye.
http://www.napaonline.com/Search/Detail.aspx?A=NNE1N3087HO_0209487468&An=599001+101992+50028+2028010+3028022+3999999#

200Amp unit. New. I was wondering if:

1. Would it fit in the same spot as the standard 3G units and
2. If it would screw something up in the electrical system if I got and installed one that large and
3. Would I still need to get the newer brackets, wires, etc to make it work?

I don't really know enough about the ECM's in these things to know how sensitive they may be. I think I would be willing to spend that much for a new Alt knowing that it would always be much more than I'd ever need.

It will work, you'll have to upgrade your charge cables.

I don't think a six rib pulley will like 200 Amps though. The price is pretty steep too.


You'd be better off to just get one from Fireguy50 and then get the 200A rectifier. Or just get a 160A from him, that is unless you need 200A.

Naw, I don't need 200 and doubt I ever would in my lifetime. It's just kinda one of those things. Bigger is better.

It's like this. I don't need a .50 rifle. I can get the job done just as easy with a .30-06. The .50 just assures me that I can without ever having any doubts or concerns that the job was done to it's fullest..........;)

Hey man, you don't have to explain it to me!! :toothless


Seriously though, search for some of Ryan's threads on the 3G swap, the pros and cons of the 200A rectifier are discussed in detail.

If you do decide to go 200A, I definitely wouldn't get one for $360

For me it's more of a convenience issue. I like the idea of getting more for less by ordering online but if the thing craps out, I like to have a local source to be able to exchange it instead of having to ship something back and wait for replacement. I'll probably just go through Advance or some place like that and get the 130amp unit for that very reason. I just saw that unit and wondered if it would be worth it or alot of hassle to make work with a stock installation. It really surprised me to see one that big in a regular parts supply house. I always figured it was one of those specialty units you had to get online.

FWIW, I recently re-replaced (don't ask...) my 130A 3G alternator with a new unit from O'Reilly. I just went in and asked for an alternator for a '95 Mustang GT (130A). IIRC, I paid about $180 and got a brand new part with a lifetime warranty -- honored by all O'Reilly stores nationwide.

No way in hell would I pay $360 for an OEM-replacement-type alternator. JMO.

EDIT: Since your truck is a '92, I think you'll need the side-mount alt, rather than the pivot-mount, so looking up a '95 GT wouldn't help you any... My bad.

He should have the pivot mount. I believe the saddle mounts were for 94-96.

My old 92 302 had the pivot mount.

I'm pretty certain I have the Pivot mount. I can't recall at the moment but I'm pretty sure the Alt mounts with the bolts going front to back and not side to side.

I run a 200A unit from back when Ryan used to sell them. You can run it, won't hurt anything. It's never putting out anything near it's max unless you are planning to winch or maybe run a super stereo and lights and junk all at once. But that price is crazy. I do have all my cables upgraded to 2GA.

Yeah, that price is crazy. Check out DB Electrical. I've ordered a lot of stuff from them, and they have great customer service and good prices. They also offer a 220 amp 3G, and you can get it in powder coated or chrome if you're interested in that kind of thing.

I wonder if they are just stock photos. The Alt I have is mounted by a different bolt pattern.

I've checked around and there just really aren't any decent car yards around here anymore. I would rather buy new froma store with warranty so that if/when I have a problem it'll be an easier replacement.

LOL, $360 for that alternator is almost funny. Doesnt have the bigger bearings or the avalanche diodes (mind you most dont). DB Eelctric units are Chinese, but not bad most of the time.
