Since there is still a lot of stuff about these not known exactly and many confusing topics, thousand of pages and myths, I will try here to make it easier. If anyone has additional information or something is not right, please post, then I will modify the 1 post. This is for stock factory transmissions only, NOT competition ones. There are A, B and C types transmissions ( C was never used in Z cars so I will not add these here ) Update 9/7-21 : Also the 4.11 ratio R180 was not used on Z cars ( correct me if I am wrong ) Also not sure if 3.90 was used in the USA on the 260/280Z and ZX So far I have: Nissan S30 Fairlady Z Japan till 1978: F4W71A manual F4W71B manual FS5C71A manual FS5C71B manual 3 speed automatic 3N71A 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.36 / 3.54 / 3.90 240Z: Datsun 240Z USA and Canada F4W71A manual F4W71B manual 3 speed automatic 3N71A 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.36 / 3.54 Datsun 240Z Europe, UK, rest of the world FS5C71A manual FS5C71B manual 3 speed automatic 3N71A 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.54 / 3.90 260Z: Datsun 260Z USA and Canada F4W71B manual FS5W71B manual 3 speed automatic 3N71B R180 Differential, possible gear ratios available: 3.36 / 3.54 / 3.90 Datsun 260Z Europe, UK, rest of the world FS5C71B manual 3 speed automatic 3N71B R180/R200 Differential, possible gear ratios available: 3.54 / 3.90 280Z: Datsun 280Z USA and Canada F4W71B manual FS5W71B manual 3 speed automatic 3N71B R180/R200 Differential, possible gear ratios available: 3.36 / 3.54 / 3.70 / 3.90 ----- ------ ----- ------ ----- ----- 280ZX: Datsun 280ZX USA and Canada F4W71B manual FS5W71B manual 5 speed Borg Warner T5 3 speed automatic Jatco 3N71B R180/R200 Differential, possible gear ratios available: 3.36 / 3.54 / 3.90 Datsun 280ZX Europe,UK, rest of the world FS5W71B manual 5 speed Borg Warner T5 3 speed automatic Jatco 3N71B R180/R200 Differential, possible gear ratios available: 3.54 / 3.70 / 3.90 Nissan S130 Fairlady Z Japan: FS5W71B manual 5 speed Borg Warner T5 3 speed automatic Jatco 3N71B R180/R200 Differential, possible gear ratios available: 3.54 / 3.70 / 3.90

Hi Guys, Going to look at a used differential this week to pair with a ZX transmission I just pulled. Was trying to think of things to check before buying. Check Diff stamp on ring gears Internal welds Metal on the drain plug Damage to spider or ring gears Play in the pinions that hold the spider gears. Damage to the pinion seal or bearings. What else am I missing? Thanks to @Zed Head for some initial inspiration here.

Hello there, I am currently on the hunt for a long nose R200 differential! Ideally I would like a 4.1 CLSD. However I will happily settle for a 3.9 CLSD. I seem to be having poor luck with local yards and shops and decided to drop back in here as I scavenge. Additionally It would be wonderful if anyone has a 280z mustache bar from a part out! ... Or anywhere really, my swap budget has been exceeded already (probably not surprising)! Any direction or advice is greatly appreciated! Note: I'm a Canadian resident and I'm willing to ship for the right part! Thanks, Wesley

Just like the title says, I'm looking for a R200 3.7 LSD diff out of a 87-89 300zx. The closer to Ohio the better.

Just wanted to know if anyone uses parts off a nissan 350z, other than the R200 rear end swap, are the disk/calipers easily mountable? or what other vehicles can you use parts off of like Brakes and or struts even...? To put onto a 78 280z with a 305. Thought i would throw out an idea and see what might come back
