Like most folks on here I have a few spares lying around but I've only just notices this :

 

Both were taken from series 4 zeds, and the one on the right is way bigger.

 

Overall the larger unit looks better built and is made by Hitachi but is also branded Nissan.

 

Is one NA and the other TT?

 

NA are 80 amp and TT are 90 amp

Possibly,

 

But both pulled from TT's.

Any part# or model markings on it?

Could just be variation in component supplier, as the model got older and manufacturing savings were been made it is likely Nissan were sourcing from more than one supplier.

Fairly sure the one I took off my car was the one on the right, but I replaced it with a earlier series alternator as there weren’t any lightweight pulley kits for the late style alternator (at the time, and my bearings were squealing like mad)

 

I’m pretty sure I’ve seen both hitachi and Mitsubishi alternators for the Z
