Complete Differential List (need help)

[Sven]

I had an early '74 260z manual, and it had an R200 in it. I'll get back to you on the ratio. It's written in a notebook somewhere...

[jgkurz]

Anyone know if the 88-89 300ZXT R200 Clutch LSD was a two pinion or four pinion?

DANA 36 vs DANA 44

 

The C-4 Dana 36 was the only axle available in 1984 Corvettes. In 1985, Chevrolet brought out the Dana 44 which was similar to the 80-82 Corvette axle, but not interchangeable. The Dana 44 axle is considerably stronger, but not indestructible. The Dana 36 and the Dana 44 (44's in some autos and all manuals) axles were used through 1996.

 

The Dana 44 is much larger than the D36. The 44 has a larger, "beefier" carrier/components to handle larger (lower) ring and pinions, and increased torque. NOTICE THE LOCATION OF THE TOP CENTER BOLT HOLE ON THE DANA 36 THATS NOT ON THE DANA 44 REAR, thats a QUICK WAY TO TELL THEM APART

[Guest turboICE]

Having looked everywhere, this site seems to have the most knowledgable R200 people around.

 

I am trying to identify a 3.538 R&P that fits the 89-90 240SX open diff (4 mounting bolts on cover, 6 bolt output shafts). I am not sure of the brand, but it already has an aftermarket LSD in it and a 4.63 R&P. The cover is stamped 4.62 LSD but I think that only a 4.63 fits it.

 

Any help identifying an existing OEM model R&P at or very near the 3.538 ratio would be appreciated.

[Guest ModToad]

Look for a 84-86 Turbo Z31 300zx R&P

 

3.54:1 open, should be a 12mm R200 - although it may be the earlier 10mm.

 

The 87-88 200sx SE (the V6 model) was for sure the 12mm R200 (both long snout) was a 3.70:1

 

Those are the only OEM ones I can think of.

[rztmartini]

I just got a diff from a guy who said it was out of a "late model" GT-R. he didnt know what year and i was wondering of you guys could help figure it out. it is a clutch type LSD but it has 4.375 ratio (35 toothed ring, 8 tooth pinion) the closest thing that was posted earlier was:

 

" R200V Short nose rear of a R32 GTR skyline, 5 bolt output

Ratio 4.36

LSD clutch type"

 

but as you can see in the pics it looks like a long nose. am i mistaken and this is what the diff came out of??

[NZeder]

I just swapped a R200 longnose 3.54 (39:11) for a R200 longnose 4.11 (37:9). The 3.54 was from a Z31 and the 4.11 from a JDM R30 Skyline.

 

I also have a R200 3.9 from a JDM C31 Laurel (L20ET/Auto) again longnose. I am sure that as visit to a local pick-a-part will find more R200 longnose with different ratios from the many JDM Nissan Sedans/Coupes from the late 80's like the two listed above.

[goodtimes]

i just checked a spare diif i've got, looks similar to the r180 i'm using, except 39:8 ratio(4.875)non-lsd. it came with the car spare when i bought it last year. i was wondering what this ratio would be suitable for?

Note Turbos:

#1) after 4/87 only-(3.7 Clutch Type LSD)

2) 88 All White SS used a 3.7 Viscous Coupling LSD)

3) LSD Unites Came With Finned Rear Covers

 

Additional Comments: a) Viscous Coupling LSD requires special splined half shafts - 84-87 R200's can be used in earlier cars, but require modifications they are not direct bolt in swapable to 240/260/280Z/280ZX's c) 84-89 R200's used a 12mm bolt in the ring gear - earlier R200 used a 10mm bolt in the ring gear, so you can not swap Gear Sets with the older R200's

Notes: The overdrive (FS5C71B) and direct drive (F5C71B) transmissions utilize the Servo-type (steel) snycro mechanism. For a complete parts breakdown of the listed overdrive and direct drive transmissions see the Nissan Motorsports Schematic catalog (99996-M8015). The shift kit (99996-E3030) is required when installing any of the listed transmissions into 240Z's built up to 8/71.

FS5C71A Conversions:

These parts will allow the FS5C71A 5-spd transmission from the Datsun 2000 (SLR311) roadster to be adapted to any Z. The R200 flang assy (38210-N3103) is required on Z's built from 12/74 to 7/75.

no info on skyline tranny and differential?

How is this then

Skyline R32 gearbox specs:

[TwinTurbo]

Sorry if this is obvious, but I'm curious if the ring and pinion out of any short nose R200 will fit in my N/A 90 300zx short nose R200 case? Something like the 3.36's from the 350Z, or the 3.545's from the 1989-1996 Q45's..

 

I do realize that to use a 10mm R&P set will require spacers, but as far as other dimensions and considerations, is it a direct swap?

 

Thanks!

Just to let you know R180s and R200s are found on R30 skylines aswell

Hi guys just took the back off a 300Z LSD I bought and it has the number NJH 35:8 AK 6 11 17. In dividing this out it is a 4.375 ratio clutch type LSD. I have not seen this ratio mentioned or in your list? Can anyone advise on what I have then?

[Mike Rowe]

I just got a diff from a guy who said it was out of a "late model" GT-R. he didnt know what year and i was wondering of you guys could help figure it out. it is a clutch type LSD but it has 4.375 ratio (35 toothed ring, 8 tooth pinion) the closest thing that was posted earlier was:

 

" R200V Short nose rear of a R32 GTR skyline, 5 bolt output

Ratio 4.36

LSD clutch type"

 

but as you can see in the pics it looks like a long nose. am i mistaken and this is what the diff came out of??

 

-----------------

Hi RTZMartini, I just posted about my diff and then found your quote above - I believe I have the same diff as you. Its a long nose clutch type LSD that came out of the first model 300Z I was told (came into Aust as a halfcut) - it has CV's and is a 4.375. Did you find out anything about yours?

 

regards Mike

[wreckedj30]

The j30's ratio is 3.9:1, mine had five bolt cv axles, and abs hookups.

[Mike Rowe]

Jimmy the diff I got came out of a Z31 300Z out of Japan. I think that is probably what yours came from as well. Are you going to use it? I'm going to but I was hoping to have a 4.1 ratio same as a GTR, at 4.375 I am wondering if it is too low?

[Guest Phizinza]

Mid 80s Subaru XT Turbo has clutch type LSD R160.

As I am a subaru guy heres what I know about the clutch pack LSD's from old subies.

 

All are R160's. All the LSD's came in 3.7:1 ratio. most commonly found (but not always) in 85-89 Subaru RX's, GL-10 Turbo wagons, and some offroad modified Subaru from 80 right the way through to 94. Most subaru owners put the LSD center into the 3.9 ratio diff's found in other Subaru's for lower offroad gearing. They go for around $400 in the US and $600 in Australia.

Oh, and they are the longnose style, they look just like the Datsun 510's diff.

[cobraz240z]

Mid 80s Subaru XT Turbo has clutch type LSD R160.

 

74 260Z 2+2 has 3.36 R200

this is probally a old post but do all the subaru xt turbos have lsd? in the mid 80's there is one in the local pick and pull but it does not say lsd on the diff cover.

[JMortensen]

I believe all the XT turbos do have LSD, but as I recall they also have a big green sticker that says 3.70 LSD right on the cover. If the one you're looking at doesn't have the sticker, that could mean that it's been swapped out at some point, or the sticker just fell off. It's going to be a bit of a gamble...
