1 tuff z Posted September 4, 2001 Share Posted September 4, 2001 quick question-is it the a/t or 5spd model 85-86 200sx-turbo diff that has the 4.11 gears? david Quote Link to comment Share on other sites More sharing options...
jeromio Posted September 4, 2001 Share Posted September 4, 2001 The one I got came from a 5sp turbo 200sx. Regardless, I would definately recommend checking the ratio before you pull it or have it pulled. Jack up one wheel, mark the driveshaft (scratch it with a nail or something), then spin that raised wheel and count the revs of the driveshaft. Should come up with about 20 and a half. Also, if you're car has a R180 now, you'll need the pinion flange from an R200 from a 280Z. The one on the 200SX unit won't work with the 280 (or 240) driveshaft. The bolts are in a square pattern, not a rectangle like the Z. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 25, 2001 Share Posted September 25, 2001 curious, how much did you pay for your 200sxt r200? I have an 85 r200sxt 5sp with a new-ish engine, and I'm thinking of maybe parting it out if I think I can get enough $ out of it... Probably can't tho Quote Link to comment Share on other sites More sharing options...
jeromio Posted September 25, 2001 Share Posted September 25, 2001 I paid $125 for mine. I paid extra to have them pull it cuz I didn't have the time. Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted September 27, 2001 Author Share Posted September 27, 2001 dewzenol, if you have a 4.11 r200, i may be interested. let me know. david Quote Link to comment Share on other sites More sharing options...
Guest Luigi Posted September 27, 2001 Share Posted September 27, 2001 Ive been looking also. have factory manuals for the 200sx, as well as fiche. according to manual 1984 AT turbo had a 4.11 R200. MT had a 3.9. 1985 MT only(?) 3.9. 1986 MT only(?) 4.11. non-turbos are either live or R180. perfect for 510's. hope this helps. I have factory manuals for all Datsun/Nissan from about 1970-1992 can copy pages and fax. www.junkyarddog.com turned up two of 'em in 5min. 150$ and 175$ Quote Link to comment Share on other sites More sharing options...
jeromio Posted September 27, 2001 Share Posted September 27, 2001 I was told that the unit that I have came from an 85 200SX turbo. I mean, I saw the car and it was obviously a 200sx turbo (I saw the turbo insignia on the outside and actually looked under the hood to see the turbo). I also did the jack up one wheel, mark driveshaft, spin wheel 10 times multiply by 2 trick (well, divide by 5, whichever) to verify that it was in fact a 4.11. I mean, the 2 ratios are really close, but I did the spin 2 times and came up with 20 and some fractional extra turn (1/2 or so) both times. And it's clearly not a R180. I had told Vinh that I would take a bunch of photos of my 4.11 with CVs and I never got around to it.....soon, soon Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted September 28, 2001 Author Share Posted September 28, 2001 jeromio, did you pull the cover to id the ratio by the ring gear? you might want to do this to be sure of what u have. david Quote Link to comment Share on other sites More sharing options...

VinhZXT Posted October 13, 2001 Share Posted October 13, 2001 David, I have a 4:11 R200 and I don't think I will find use for it. I did open the cover up and it's has a 37:9 stamped in the ring gear. This R200 fits the 280Z R200 half shafts fine but it will not fit the 280ZXT half shafts. I had a discussion with Jeromio about this awhile back. I am in Philly Pa. Let me know..

Guest Anonymous Posted September 28, 2002 Share Posted September 28, 2002 Can someone clarify the method for determining the actual gear ratio. I kinda got lost with the spinning the wheel and driveshaft method. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 1, 2002 Share Posted October 1, 2002 DAW, So if I understand you correctly, I don't need to bust my hump trying to find a 85-86 Turbo 200SX rear end only. I can get the 4:11 out of a V6 200, or the 300zx? Quote Link to comment Share on other sites More sharing options...
johnc Posted October 1, 2002 Share Posted October 1, 2002 The only sure way to verify the rear gear ratio is to pull the diff cover (12mm socket) and look at the ratio stamping on the ring gear. Quote Link to comment Share on other sites More sharing options...
jeromio Posted October 1, 2002 Share Posted October 1, 2002 I stand firmly by the wheel spinning test. You can't count on a 17 yr old car having all it's original parts. Also, I'm pretty sure that no 300ZX ever came with a 4.11 (Stock that is). I also don't think 200sx V6 or NA models had the 4.11 R200.

quicker240 Posted October 2, 2002 Share Posted October 2, 2002 pull rear cover,find stamp on ring gear and divide.39 (teeth on ring gear) divided by 7 (teeth on pinion gear)= 4.1111 ,simple! Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 2, 2002 Share Posted October 2, 2002 I doubt that my local salvage will let me remove the cover to count teeth or see the stamping. I agree that this is the best way to verify the 4:11, or look at the engine stamping as posted earlier. Can someone clarify the wheel spin test. I assume you would turn the wheel 5 times and count the drive shafts revolutions to 20.55, or 20 1/2. Are any of the stampings on the outside of the case of any use? My R200 has several numbers stamped on the top of it. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 9, 2002 Share Posted October 9, 2002 fastest way i have found is to pull the speedo gear i think its got 21 teeth i all so think with the stick car its pink and is the R200 i have seen some R180 4:11 with 21 teeth also a turbo but auto Z Sport mag has a nice wright up on that by Ken Jones O ya i did all the work he just put it on paper Quote Link to comment Share on other sites More sharing options...
