Why does it matter?

I imagine it's unlikely to be Borg Warner, as I think the Japanese Warner business is Aisin Warner, who make the freewheeling hubs, auto gearbox etc. My guess would it would be Aisin Warner.

Suzuki diffs have the Hitachi symbol cast into them.

Just had a look myself and so they do.

Good to see you know your diffs. If you are thinking of the housing than its fabricated, not cast. Only the center section is cast.

Had a feeling it was a Hitachi as I looked at a friends datsun 1200 ute and looked similar and he was after an LSD so figured he could probably use a Suzi one but the 1200 ute is H165 meaning 165mm most likely or 10mm out if the suzi one is 175mm.

Now on my side of things I finished a modded g16b conversion into a 99 model carry and the diff has started to go apeshit from the torque and wheel spin no thanks to my spirited driving style since I fit a bigger exhaust.

Its a piddly 8 bolt diff of some kind so thinking its the same as the early Sierras and 4.33 something ratio.

Id like to fit a 4.1 or 3.9 as the engine pulls even from 4th gear in almost any revvs and could do with 5th gear having more legs rather than revs. I will have to make sure I change my lead foot as the bigger diameter stickier 185/65/14s also wont help destroy the diff sooner.
