Have just bought a R180 LSD out of a Subaru (very cheep off ebay) and have from years ago a new pair of 280zx drive shafts the drive shafts go in the diff as if i had them made for the job had the car up at mark warbys a few weeks ago the diff looks to be the same size/shape & fittings will be doing the conversion in a few months so will let you all know the results.

Interesting read I just found .... I assume it's right ?

Nissan owns part of Subaru, which is actually a division of Fuji Heavy Industries, which uses (like Nissan) Hitachi R-160 diffs for some of their cars. How do they fit? The Subaru diffs (both LSD and non-LSD) bolt in just like the stock R-160
Above is referring to a 510 tho :unsure:

So if a std 240z uses an R180 diff then hopefully a 3.5 R180 LSD from an Impresser will fit straight in a 240? (If the 240 drive flanges pop out and fit the Subaru diff ok?)

and found on another site ...

R160, R180 and R190
These were IRS (Independent Rear Suspension) differentials with long snouts. The "R" stands for Fuji Heavy Industries.
Well I neva :D

Z31 diff

Anyone got any pics of a Z31T diff? Will it fit into a 240?
Is it the same ext as the 260 R200?

Has anyone any info on Z31 rear diffs?
I've just been to look at a Z31 in a breakers yard, G plate, 3.0 manual, na non turbo! I read and therefore assumed if it has a finned rear cover it will have an lsd? Yet it was easy to turn one shaft without the other moving? I take it that isn't a lsd then :confused:
Either that or it's fooked :unsure:

btw, whilst I was there I did spot a 88 2.4 laurel injection :eek:
Looks just like it has a long nose diff, the same as a zed but uses push in shafts like the Z31 :eek:
Diffs any good in them ? :D
