    Did a search but nothing came up. I am looking to upgrade from the weenie stock one to something in the 140 amp class. I run a winch, fuel injection, rock lights, stereo, CB with some "heat", and fixing to install the Ford Taurus 2 spd elec fan setup. I was looking at Powermaster or Iceburg. What do some of you run for alternators?
    Thanks /forums/images/graemlins/thumb.gif

    My first job was at a Alternator and starter rebuilding shop. I highly recomend finding a local Alternator shop and have them build your Alternator up. It'll save you money, and if it has any problem, it's close to take back for repair. We normally did a 1 year warrenty.

    These guys have an impressive array of solutions: http://www.alternatorparts.com /forums/images/graemlins/cool.gif

    They also have the best price on Iceberg upgrade kits that I've seen anywhere. /forums/images/graemlins/thumb.gif

    I run stock one myself. But what i was thinking of doing i know some of the people here have done is use 2 stock style alternators. Even though one might generally carry the load, if it is overcome the 2nd one kicks in and helps out. Also would be useful in the event of a crapped out alternator. Just a thought. Good question. /forums/images/graemlins/thinking.gif

    there was a link posted on here before about using a 140 amp alternator from a '94 pontiac transport with an adaptor plug. i don't remember the link, but the alternator is about $100 from autozone, and the adaptor was about $20 from the dealer.

    See my link above. $96.99 for a lifetime warranty alternator from autozone.

    Application is 1994 Pontiac Transport 3.8L WITH REAR A/C

    WOULD THE PONTIAC ALTERNATOR WORK IN AN 1989 K5? CAN I STILL USE THE SAME ALTERNATOR BRACKET? :confused:

    I just did this two weeks ago with the pont. transport alt. Best thing I ever did. I did have to modify the brackets . I had to relocate the top hole in the bracket and weld a tab to it so I could have some material to drill a hole in. Also for the bottom bracket I had to add a tab and re-drill a hole cause the alt. is big. It works great at idle as well.

    The biggest issue with "souping up" a stock 12SI alternator is that you typically only see a slight improvement in output at idle or slow speeds, which is where you really need it. The simplest swap is to upgrade to a CS144 large case alternator, you can either buy a new AC Delco unit or get a reman'd one at Autozone like suggested above (though if you go the AZ route they typically have core charge).

    Sorry, not trying to hyjack, but I picked up a couple of cs144's at Pick n Pull for $7.50 each...:cool1:

    Does anyone know if they make a rebuild kid for them? I looked online and couldn't fine one past the cs130.

    My first job was rebuilding starters and alternators also!!!
