Now that I have done some more digging, I plan to go with a 105 amp CS130 unit. Should be enough for me, seeing that I currently have a 76 amp 12si model.
The XJ/MJ:
- 1984-1986 had the Delco SI (12SI, I believe) alternator
- 1987-1990 had the Delco CS130 (some 4-150 engines had the Delco CS121.)
- 1991-up got the Nippondenso.

The YJ got the Delco 12SI through 1990, went to the ND for 1991-up.
All TJ got the Nippondenso.
All ZJ got the Nippondenso (in two frame sizes, the V8s were slightly larger, since they had higher output.) Ditto the WJ and WK.

The Delco SI and CS series are both internally regulated, while all of the Nippondenso alternators used by ChryCo were externally regulated (with the regulator inbuilt into the PCM.)

They won't change over as a "drop-in swap" - using a Delco in place of the ND will throw a persistent code (since the PCM won't pick up on the field switching actually doing anything,) and swapping the Nippondenso in place of the Delco will require the addition of an external regulator (nearly any unit will work - many people use an early Chrysler external regulator, and the Prestolite marine-grade units are also quite common.)

Great write up Dirt!

There used to be a write up on this, on some Canadian website, but it disappeared from the internet. Que managed to copy it, and posted on a different thread. Maybe this will help with some questions, you guys planning to do this might have.
