getoffmyinternet Posted February 26, 2012 Share Posted February 26, 2012 $400+ for just the gears is outrageous. In the nismo catalog I didn't see anything besides 3.7? When I was looking for gears I saw that guy on ebay and asked him if they work for the z31 r200 and he said no, not sure why though I didn't really research further. Actually looking at those, I assume they're all for a short nose R200. You might be in luck though if you want to go from 3.7 to 3.9 because it seems like you'd only need to swap the ring, since the pinion on both versions is still 10 teeth. I've never heard of a driveshaft being called an arm, but I think that would throw me through a loop too. We already have enough trouble with stub axles/stub shafts around here Quote Link to comment Share on other sites More sharing options...

We already have enough trouble with stub axles/stub shafts around here THEY ARE STUB AXLES DANG IT ALL! arg I currently have a 3.545 rear set in the factory r200 (which i THINK is a short nose??? i have been getting mixed up about what is a short nose and what is long...)so I guess I am missing what you mean going from 3.7 to 3.9?

getoffmyinternet Posted February 26, 2012 Share Posted February 26, 2012 Oh right I forgot you said that. Can't tell if it's long or short, that's a bad sign... http://bit.ly/yv1IPb Oh and I forgot half shalfts is another one ugh. Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 26, 2012 Share Posted February 26, 2012 More informative reading - http://forums.hybridz.org/index.php/topic/32313-putting-lsd-in-non-lsd-r200/ The simple route to OBX LSD with the gear ratio you want seems to be to buy an open differential "assembly" with the desired ratio (~$90 at the local Pick n Pull), then bolt the ring gear on to the OBX carrier/differential/center/whatever and re-assemble. Here's a thread about long-nose, short-nose, etc. - http://forums.hybridz.org/index.php/topic/49194-differential-cv-lsd-hp-torque-r160-r180-r200-r230-diff-mount/ Quote Link to comment Share on other sites More sharing options...

getoffmyinternet Posted February 27, 2012 Share Posted February 27, 2012 Sure you're aware of google, but you're not using it. The difference between a short nose and a long nose is obvious when you see one picture of both. Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 27, 2012 Share Posted February 27, 2012 The proper term appears to "differential case". The carrier is the "pumpkin". Quote Link to comment Share on other sites More sharing options...

getoffmyinternet Posted February 28, 2012 Share Posted February 28, 2012 That's understandable. I forgot it's not always springtime in some dark corners of the world. Actually it's sprinkling today and the whole state basically shut down Suffice it to say all Zs had long nose diffs. Therein lies the problem, if you had a short nose diff we wouldn't even be having this thread right now, they're a dime a dozen, which is why many people spend the time and money converting their setup. People I know refer to the case as the pumpkin, at least for solid axle diffs, because the center of the housing is rather spherical. I still hate the term either way.
