There were 11 different differentials offered in the Z31. They are all R200 models Made by Hitachi I think? The differences are as follows:
- USDM 300zx 84-87 NA = R200 3.700:1 open 37 tooth Ring gear 10 tooth Pinion
- USDM 300zx 88-89 NA = R200 3.900:1 open 39 tooth Ring gear 10 tooth Pinion
- USDM 300zx 84-86 T and JDM 84-89 T= R200 3.545:1 open 39 tooth Ring gear 11 tooth Pinion
- USDM 300zx 87-89 T = R200 3.700:1 clutch LSD * 37 tooth Ring gear 10 tooth Pinion
- USDM 300zx 88SS = R200 3.700:1 viscous LSD ** 37 tooth Ring gear 10 tooth Pinion
- EURO 300ZX Turbo Sold in Europe = R200 3.364:1 open 37 tooth Ring gear 11 tooth Pinion - 4 spider gears
- EURO 300ZX Non Turbo Sold in Europe = R200 3.700:1 open 37 tooth Ring gear 10 tooth Pinion - 2 spider gears
- EURO 300ZX Turbo Sold in the Europe = R200 3.545:1 open 39 tooth Ring gear 11 tooth Pinion - 4 Spider gears
- EURO 300ZX Turbo Sold in the Middle East = R200 3.545:1 open 39 tooth Ring gear 11 tooth Pinion - 4 Spider gears
- EURO 300ZX Non Turbo Sold in the Middle East= R200 3.700:1 open 37 tooth Ring gear 10 tooth Pinion - 4 Spider Gears
- EURO 300ZX Turbo Sold Else where = R200 3.545:1 open 39 tooth Ring gear 11 tooth Pinion - 2 Spider gears
- EURO 300ZX Non Turbo Sold Else where = R200 3.700:1 open 37 tooth Ring gear 10 tooth Pinion - 4 Spider gears
- JDM 300zx Manual = R200 3.545:1 open 39 tooth Ring gear 11 tooth Pinion - 2 Spider gears
- JDM 200Z ZS ZG Manual and Auto = R200 4.111:1 open 37 tooth Ring gear 9 tooth Pinion - 2 spider gears

- JDM 300ZR Manual and Auto = R200 4.111:1 clutch LSD - 37 tooth Ring gear - 9 tooth Pinion - 4 spider gears
USDM Cars only *Only 87 Turbo cars made after 04/87 had a LSD. Before this, they were open differentials. Canada did not get a LSD until the 88 model year.
USDM Cars only ** Only available in the 1988 Shiro model
On the Limited slip differentials a finned rear cover was added from the factory. This is a usual dead giveaway of a LSD in a Z31 in the USDM.
EURO market cars Sold in Europe had an external Differential Oil Cooler installed. This Consisted of an Electric pump, Oil Cooler, and lines as well as a Temperature switch.
Driveshaft Yoke/Flange[edit]
There were two different Yokes that were used on the Z31 models depending on years. Early Models had a rectangular flange and bolt pattern and the Late models had a circular flange with a square bolt pattern.
Diff Fluid Recommendations USDM:[edit]
- R200 - 3-7/8 pt.
- Open diff: API GL-5
- Clutch diff: API GL-5 and SAE 80W-90 approved for Nissan LSD
- Viscous LSD: API GL-5 and SAE 80W-90
Diff Fluid Recommendations EURO:[edit]
Location of Sale | Oil Capacity - Liters ( IMP PT) | Oil Type | Europe | 2.1 (3 3/4) | API GL-5 | Middle East | 1.8 (3 1/8) | API GL-5 | Other | 1.3 (2 1/4) | API GL-5 |
