Alternator Upgrade

fmlewis · 09-28-2010, 01:57 PM

I have been doing some research on upgrading my alternator. I have an `83 4.2L. I recently acquired a Ford Taurus Radiator fan and plan to install that along with a higher output alternator. Do to the current from fan and room for future mods.

I currently have the stock 63amp version. Anyone know of a 120 - 165amp version that would be ideally a direct drop-in no fabrication work. If so, what year/model vehicle would it be found on? If not, to what extent of fabrication is needed.

What have you guys done who are running the taurus fan?

well I do not have a 120 amp but do have a 105.

1990 jeep wrangler 2.5 motor with ac it is 105 amp. I just swap out the pully that comes on it with the V belt pully and have been useing it.

They are 90ish and come with a warranty at the local part stores

All the delco alternators are listed. Notice the CS alternators have a different plug that you can get an adapter for.

Stay away from the CS 130s, they overheat and shut down and are open to dirt.
