Ok so I searched and found some info about this.
Mine is a 1992 D21 so it has the 70 amp alternator?
I want to go to 100 - 110 amp.
I understand this might/can cause problems.
Any ideas?
Thanks in advance

Hitachi JFZ1912 is the code you are looking for at the wreckers.

Comes back to a 24v item with a ripped pulley?
Hmmm also says they come in a 12v fitted to a nissan sentra?

Not much point in upgrading your alty unless the new one comes with a vaccy pump on it. The alty on the TD's have a vaccy pump where others have a mechanical one on the engine as I have now

my bad forgot the pre 96 has the pump on the alt.
the green sticker should read something like No.:23100-02N14/15/18/19 with a capacity of 50cc

There is no easy upgrade as there are no decent output vac pump alternators.
The highest output one i can think of that will fit is the 80 amp isuzu bighorn unit but they are prone to failure just like the original terrano one.

Make sure it has a vac pump. The only 100 amp alts on terranos are the later R50 units and they dont have a vac pump.
