Guest Anonymous Posted January 18, 2001 Share Posted January 18, 2001 That message just got me thinking........... non turbo z32 has a r200 viscous lsd with a 4.08 ratio in a z32 style case. Why not take a gearset from one of those and put it on a r200 clutch lsd in a z31 style case so it bolts right into a s30? I would assume that r200 lsd is r200 lsd, regardless of which case it's in. ie. 12mm ring gear bolts. Does the z32 style case use the same length pinion as a z31 style case? If so, this should work and leave you with a 4.08 clutch r200 in a z31 case, which would be very nice. Also, I just aquired a clutch lsd assembly with a 3.7 gearset and a finned cover. Anyone ever put together a r200 and had good luck as far as reliability and gear life goes? Once I get my lsd in I'll have a case with good bearings and want to attempt to assemble the parts into a whole r200 clutch lsd in a z31 case. And anyone got one of those quaffie torsen diff assemblies? If so, comments? ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 18, 2001 Share Posted January 18, 2001 SO WHAT YOU ARE SAYIMG IS IF YOU HAVE A R200 VISCIOUS IS THAT THE R200 OPEN DIFFERENTIAL SHAFTS HAVE A DIFFERENT SPLINE THAN THE VISCIOUS DOES. YES I AM GETTING MYSELF CONFUSED. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 18, 2001 Share Posted January 18, 2001 Have you ever considered typing normally, instead of all caps, which is annoying and difficult to read? ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 18, 2001 Share Posted January 18, 2001 sorry for such the large type i am at work, shhh, don't tell anyone and we use the capitals for everything. anyone have an answer to the question though. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 19, 2001 Share Posted January 19, 2001 Yes, if you read any of the hundreds of pages with diff info you will find out that the viscous diffs use a different spline pattern than the open and clutch diffs do. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted January 21, 2001 Share Posted January 21, 2001 Yeah, caps tick me off too Has anyone looked at the viscous LSD gearsets to see what size bolts they use? I know they don't use the same shafts due to spline count but what else aside from that and the type of LSD is different? Quote Link to comment Share on other sites More sharing options...
pparaska Posted January 21, 2001 Share Posted January 21, 2001 ALL CAPS don't really tick me off, but it's so much harder to read, I generally just don't and skip it. Quote Link to comment Share on other sites More sharing options...
Mikelly Posted January 22, 2001 Share Posted January 22, 2001 Guys I think 76 280 Speeder made a simple error in typing, nothing more... Was it really necessary to beat up on him? I don't think any of us walk on water around here, unless something special is happening in Alabama that I'm not aware of......

BLKMGK Posted January 23, 2001 Share Posted January 23, 2001 Mike, it's sort of a thing that's built up - for me at least. I see all caps in a few messages but try to hold my tongue, it's pretty hard after awhile It hurts my eyes and in "netspeak" it's seen as shouting. Granted, not everyone is an old hand at writing on the 'net or had experience with BBS type forums so I try not to be nasty when I comment on it. And yes, I know I'm guilty of lousy typing which is also hard to read sometimes - 30wpm or so with just two fingers leads to errors I'm afraid. I've also lost some of my old "edge" in speeling So, has anyone looked at the viscous gear sets to see what bolts they use? I suppose since it now seems I've got an R200 open diff in the garage I ought to look and see what bolts it uses just for kicks. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 23, 2001 Share Posted January 23, 2001 first, i just wanted to say sorry for the large type i didn't know that i was annoying anyone. when i am at home i use regular type and when i am at work i have to use large type for the old farts here that can't see. i will try to do better about taking the caps lock off when i type in a message. second, the viscious unit is what i was trying to see if i could bolt it into a r200 case and retain my 3.54 gear instead of using a 4. something gear. i haven't been able to test the theory yet but if anyone has already tried it then give me a heads up. later, chris Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 23, 2001 Share Posted January 23, 2001 As far as I know, all LSD r200 diffs use 12mm bolts - I know the OE clutch diffs do, and I assume the viscous diffs do as well. All open r200 use 10mm ring gear bolts. I ignore all caps stuff as well. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 23, 2001 Share Posted January 23, 2001 i have a feeling that the viscious is going to be a 12mm bolt as well but i didn't know if anyone has really torn one apart and tried it. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 24, 2001 Share Posted January 24, 2001 Everyone, I may be starting rumors here but I think the diff's in the 280zx turbo's had 12mm bolts. If this is true than the gears from these could be used. I have one with the 3.54 ratio and i've seen plenty at our local pull-a-parts. I also have heard that the 200sx turbo used 12mm bolts & the had 4.11 gears. Any body know if this is true? Glenn Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted January 25, 2001 Share Posted January 25, 2001 Speeder - if you're just tyring to keep from getting a 4 series gear go for the clutch LSD from the 87.5-89 turbo 300ZX - these are ALL 3.7's. The 200SX cars with "mag wheels" are supposedly the ones with LSDs BTW. Zcar.com had a couple of good threads on it last I looked in their archives Quote Link to comment Share on other sites More sharing options...
Mikelly Posted January 25, 2001 Share Posted January 25, 2001 Well to anyone trying to figure this whole thing out... I have the 3:7 R200 and would GLADLY trade for an R200 LSD with 4:?? Gears in it. It would make my CAM/T56 issue go away.

Guest Anonymous Posted January 25, 2001 Share Posted January 25, 2001 I have looked into this alleged clutch lsd in some 200sx cars - they don't exist. The ONLY place to get the OE r200 flat plate clutch lsd is in 87-89 300zx turbos made after 4/87. And they're all 3.7 ratios. Someone on z31.com said they got a 4.11 from a 200sx turbo and it was a LSD. I don't know why he thinks it is, perhaps because he leaves 2 black marks instead of 1? At any rate, such a beast was never made. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 25, 2001 Share Posted January 25, 2001 I was going in favor of trying to get the viscious unit to work with the 3.54 gears instead of using the clutch type with 3.7 gears which is perfectly fine gear ratio also because i have heard that it is hard to get the clutches to rebuild the rear end. the viscious unit you shouldn't have anything to rebuild if i am thinking correctly.

Guest Anonymous Posted January 25, 2001 Share Posted January 25, 2001 The viscous r200 is 3.7 as well. Unless you're talking about the viscous LSDs in the z32 style case, which are 3.08 and 4.xx and are difficult to install. The clutches are readily available, you can order them from any nissan dealer, as you can all other clutch parts. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 25, 2001 Share Posted January 25, 2001 well i guess with all that info then i will go with the clutch lsd and just rebuild the clutch pack. the hard part here is just trying to find a 87-89 r200 lsd. here is another question, will the 3.08 gear set from the z32 viscious case fit directly into a z31 r200 clutch lsd? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 25, 2001 Share Posted January 25, 2001 No. The 3.08 in z32 turbos is a r230, not a r200. I think the pinions are different as well, but I'm not sure. I have a spare clutch lsd and a spare clutch LSD assembly(3.7 gearset, clutch assembly, and finned cover) that might be procurable for the right price, but I'm not exactly dying to sell either. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
