rb26zed Posted August 28, 2005 Share Posted August 28, 2005 I got a R200 from a GTR today with 4.11 ratio clutch type lsd and 6 bolt output. The front GTR R180 is also 4.11. Also the output stub axles on the GTR R200 are larger than the regular 5 bolt R200's. Link to comment Share on other sites More sharing options...

Tekira Posted October 30, 2005 Share Posted October 30, 2005 I dont think the 260z 2+2 has a r200. I have a 260z 2+2 and it has a r180 3.36 Wait, now i am confused. I thought i had a r180. But the r200 in that pic looks like my diff. Link to comment Share on other sites More sharing options...

HS30-H Posted November 21, 2005 Share Posted November 21, 2005 R190' date=' Long Nose 240Z 432R Ratios 3.90 two pinion clutch LSD R190, Long Nose Nissan Motorsports Any Ratio four pinion clutch LSD R200 long nose, 280Z, 280ZX, 300ZX Ratios 3.36, 3.545, 3.70, 3.90 LSD April 1987 and newer turbo [/quote'] Nissan Motorsports: R190 any ratio and four pinion clutch LSD. Nissan 240Z 432R: R190 3.90 with two pinion clutch LSD. Nissan Fairlady Z432 ( PS30 ) and Fairlady Z432-R ( PS30-SB ) from 1969 to 1972 came with the 'R192' in 4.44 ratio and 2-pinion clutch LSD. Same diff ( with different rear cover ) was also fitted to the PGC10 and KPGC10 Skyline GT-R in the same period. 'R192' was exactly the same as the 'R190' offered by Nissan Motorsports in the USA' date=' but was 2-pinion instead of 4. A 4-pinion version was available as a 'Sports Option' part in Japan, in ratios of 4.625, 4.875 & 5.125, but it was [i']still[/i] called 'R192'. 1973 Z432 and Z432-R models came with the R200 in 4.375 ratio, and a 4-pinion clutch LSD. This was also fitted to the KPGC110 Skyline GT-R. Again, 'Sports Option' ratios were available - this time 3.7, 3.9, 4.1, 4.375, 4.625, 4.875 and 5.143:1. Alan T.

pparaska Posted December 29, 2005 Share Posted December 29, 2005 I believe the R200 3.545 is 39 ring teeth, 11 pinion teeth -> 39/11=3.5454 (repeating digits) For the R230 to be 3.538, my guess is thats 46 ring teeth, 13 pinion teeth -> 46/13=3.538461 (repeating last 6 digits) 2 more pinion teeth for nearly the same ratio helps with strength, I'd suppose! Jim Biondo used to brag a bit about the 3.15:1 set he had in his V8 260Z's R200, saying it had more pinion teeth, so it was stronger because of that. Of course, it's probably more than the number of teeth, but the size and geometry of them. I'm guessing the 3.15:1 R200 set is 41 ring teeth, 13 pinion teeth -> 41/13= 3.153846 (repeating last 6 digits). If that's true, that's 2 more pinion teeth than the 3.545 R200, but the teeth are probably similar is size. The R230 teeth I'd suppose are larger (larger pinion diameter?). Any way you look at it that R230 is a pretty durable gear setup. I guess the only thing to look out for is wearing out the viscous coupling? I think those of us with the 3.700:1 (37 ring teeth, 10 pinion teeth) probably have PINION ENVY. Link to comment Share on other sites More sharing options...
JMortensen Posted December 29, 2005 Share Posted December 29, 2005 There is something to be said for a large pinion head. I used to see quite a bit more breakage out of the low gearsets than the high gearsets when I was selling diff parts. Thing is on Z diffs you don't hear of people shearing teeth off the pinion too much. Every once in a great while, but for the most part it seems like the pinion gear isn't really the issue. The lower the gear ratio the smaller the pinion head and the thicker the ring gear is. It gets to a point with some of these ratios where the pinion head is ridiculously small. We had a 7.33:1 R&P for a Ford 9" at the place I worked for. That is ridiculous. I think if you have the 3.54 vs the 3.538461, they both have basically the same SIZE head IIRC (in comparison to the ring gear diameter), but one has smaller finer cut teeth than the other. I wonder if it really is stronger with the smaller teeth though, Nissan may be doing that more for noise reduction. Link to comment Share on other sites More sharing options...
JMortensen Posted December 30, 2005 Share Posted December 30, 2005 Also with regards to the R230 nobody has really brought up the crush sleeve as a potential weak point. I know that was considered a weak point by the 9" and Toyota people, and I used to sell lots of solid spacer kits to replace the sleeves especially for drag racers. Haven't been following all of the R230 threads, but I was pretty surprised when I saw one a while back that said it had a crush sleeve. You 230 guys doing anything about that?

v8dream Posted January 3, 2006 Share Posted January 3, 2006 My usually trustworthy machine shop guy just called to say that he had damaged one of the carrier bearings while trying to swap them to my new LSD unit. Are all r200 ring gear carrier bearings the same? If they are not, does anyone have a part number? My r200 is a 10mm bolt unit. No idea what year it was from because it was sitting in the passenger side footwell of my '73 when I got it. And does changing the bearings mean that I will need alternate shim thicknesses? Thanks in advance for the help. Link to comment Share on other sites More sharing options...
v8dream Posted January 3, 2006 Share Posted January 3, 2006 I think I figured it out. The industry standard designation is 30209, sometimes with a "C" on the end. 30208 fits r180. Link to comment Share on other sites More sharing options...
Mack Posted January 30, 2006 Share Posted January 30, 2006 The M30 diff is a long nose R200 with an ABS sensor in the snout. It has a 47/12 gear set and 4 pinion gears. pretty beefy. the J30 is a short nose R200 (also 47/12) with a viscous coupling LSD unit. it comes in 5 bolt and 6 bolt (3 groups of 2) flavors. some have the ABS sensor in the snout, some have them on the halfshafts. these are usually good canidates if you are looking for an R200 viscous, because they havent all been beat to ****. no one drifts a 4 door luxo liner, lol!
