Id go with a 3G upgrade, and dual batteries. I got mine from here, Chris made his from a junkyard 3g alt. http://rjminjectiontech.com/?p=6

I also would like to know what is the biggest parts swap you can upgrade to without having to upgrade wiring, etc.

I'd like to do one of these upgrades but i would have to change out way to much stuff...

Any upgrades should really be upgraded with wires also...

Yeah i'm just going to wait untill I can get a Ron Frances wiring harness, and go with a 200amp Alt.

100-130 amp

Ryan-- any upgrade at all will require a new charge cable; that's just the way it goes.

As far as the 200amp alternator is concerned--- I read somewhere on RJM Injection (this guy knows his stuff about alternators) that anything higher than his 160amp alternator is useless because the belt will slip on the pulley when you pull that much load. Keep in mind that your alternator is somewhat of an electromagnet and it's potential is not limitless. RJM sells a 200amp alternator and could easily take your money by telling you it works fine-- but he added that disclaimer about it anyways and basically said use at your own risk. That makes me trust his word.

You can piece together a 130amp alternator or buy one from your local parts house. They can be found on some 3.8L Taurus engines, some Explorers/Rangers, and late 7.3L Powerstroke engines. Or you can buy the 160amp from RJM Injection-- I believe it's got all 130amp components except with an upgraded 160amp rectifier.

The charge cable that you'll need for the upgrade can also be found at RJM Injection:

serpintine belt systems, and dual v-belts will work with the bigger alts, but just a standard v-belt wont hold it.

Hey Wizz, check out Jegs, they sell Alts brand new that are pretty much plug and play no moding needed to get them to work other then changing out the charge cable
