I'm looking at putting in a more powerful alt for charging of my batteries. I did a search because I swear this has come up before but I didn't find what I was looking for.

Rob, didn't you put in a higher capacity alt that just bolted right on? I think it was a bosch?

I found a 65 amp for an 87 2.6L w/o
intercooler. What's the stock output on an 87 Monty 2.6... isn't it 45 or 50 amp?

An 87 Monty (from memory) is 45 Amps. The Starion for 88-89 is a 75 Amp unit. There are other alternators with a similar case that have a higher output. I donít have the info handy but can around for it later.

The Starion is a bolt in....

Thanks Kevin,

I was going through the archives and stuff and got the info I needed also. I think I'm going to find a starion unit for the 75 amps.

Here's a link for an ebay alt if anyone cares...

I'll post pics here in a bit, but why don't you do an alt. conversion ???

100+amp output depending on model and no more crappy under-rated Mitsu alts.????

The 75a Starion alt. will put out 65-70 if the planets are aligned and magnetic poles both go + <img border="0" title="" alt="[Eek!]" src="images/icons/shocked.gif" />

A new 75 right from the stealer puts out 70a at only 13v.....65a at 13.8

Time to try the new macro lens !!

Well originally that's what I was thinking...

Here's the post I was referencing when we were discussing this last summer.

As I see it, it's a possible thing to do but we have to upgrade the wiring for the increased load... correct?

I know...but why dick around with crappy over priced, import alts ??? After you make the simple bracket, you can put any GM unit you want..

I choose the 21SI Series Alternator which is 160a and go up to 250a depending on the unit...These are the units that Ready Power Systems uses in the portable welder applications that all the Jeep guys have...

This unit is mainly used in the big boys like Bluebird Bus, Freightliner, Gillig Equipment, HME Equipment, Kenworth Truck, Mack, Peterbilt, Volvo White-GMC...

Anywho, you can pick these units up for around $100 from http://www.motorcityreman.com/..

Here's my original post.. http://www.4x4wire.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=69;t=008999

Here's some quick pics...(these were a pain in the arse to get !!)

Top view of the alt, you can see my bracket which is made of aircraft grade 2024/6061 aluminum (it was leftover stock from my dad's new plane <img border="0" title="" alt="[Embarrassed]" src="images/icons/blush.gif" /> )...Simple design...pretty easy to do...there's no modification to the top compressor bracket or adjustment unit..
<img src="http://www.montero4x4.com/images/alt1.jpg" alt=" - " />

Ass-view from the back, notice the big 4gauge wire that goes to the bat <img border="0" title="" alt="[Eek!]" src="images/icons/shocked.gif" />

P.S. Yes I know I'm missing the rear compressor bolt <img border="0" alt="[Hillbilly]" title="" src="graemlins/notooth.gif" />

So for the wire going to the battery you went with 4 gauge? Was that the only thing you changed?

I have a dual battery setup now and I think I'm running two gauge but I'll have to check it out.

The bracket you made... it looks like it's just an oval piece with two hole in it... true?

Oh, I still owe you a call about the digital editing... what don't you do?

Nice pics by they way...

The gauge going from the alt to the bat only depends on the amp output of the alt..

You can have a 50a alt, and run 4 batteries and only need 10gauge wire cause that's all the load it'll ever see..

I'm running 4awg. AmpKing wire which is OFC and ultra flexable...It'll handle the 160a the alt puts out without any problems...

For my winch and dual Optima (soon to be Orbital <img border="0" title="" alt="[Wink]" src="images/icons/wink.gif" /> ) setup, I'm running 2awg AmpKing for that side...

But it'll see 400+amps without any problems <img border="0" title="" alt="[Eek!]" src="images/icons/shocked.gif" />

As for the video editing, I just finished a corporate video for a client that my wife's company just signed.....So I'm ready to go...

Jack of all trades....Master of none <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" />
