guns Posted February 6, 2014 Share Posted February 6, 2014 I pulled a r200 form a 87 turbo 300zx today. When i cracked it open did not look like a lsd or open diff . I was hoping someone could help me id it when i held the the drive shaft and spun one cv axle the other spun in the opposite direction when i spun the drive shaft the only one cv axle spun it did not have fins on the back of the case. im hoping its a lsd or vlsd all the r200s i came across so far you can see the spider gears very easy thanks for the help Quote Link to comment Share on other sites More sharing options...

socorob Posted February 6, 2014 Share Posted February 6, 2014 Didnt the turbo have a clutch LSD? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 6, 2014 Share Posted February 6, 2014 Not that one, apparently. 87-89 had them. Maybe that was an 86 or had a diff swap or something. Quote Link to comment Share on other sites More sharing options...
guns Posted February 6, 2014 Author Share Posted February 6, 2014 i thought all r200s are 4 pinion. can you tell me why the spider gears are covered up so much never seen this before, and i cant find a pic online of one like it? Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 6, 2014 Share Posted February 6, 2014 Isn't the machined outer surface of the carrier the odd thing for a Nissan R200 diff? Most have a rough cast outer surface. Is that an R200 or an R180? Seems skinny, but I don't know that they put R180's in the 300ZX's. Quote Link to comment Share on other sites More sharing options...
guns Posted February 6, 2014 Author Share Posted February 6, 2014 (edited) its the same size as my other r200 the machined outer surface of the carrier is what i cant figure out and in the center of the spider gears there is something in it not just the rod like I am use to seeing here a pic of what all my r200s before looked liked Edited February 6, 2014 by guns Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted February 6, 2014 Share Posted February 6, 2014 I've seen guys get pissed in the classifieds when guys insist on photos with the cover removed. This is why. Many of us have bought an open diff that came from a car that is SUPPOSED to have a CLSD or VLSD. There's a lot of weird parts floating around after 40 years.

johnc Posted February 6, 2014 Share Posted February 6, 2014 As Jon said. 4 pinion open diff. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 6, 2014 Share Posted February 6, 2014 The picture above is a 2 pinion. The reason the carrier has to bolt together on the OP's diff is that you can't have a big window in a 4 pinion carrier. There just wouldn't be any way to get the pinions in there, because the cross pin shaft is an X, and there wouldn't be anyplace for the pinions to ride on the case, so the carrier bolts together instead. Here is a thread where they disassemble the 4 pin open: http://z31performance.com/forum/z31-performance-forums/driveline/12411-four-pinion-open-diff Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 6, 2014 Share Posted February 6, 2014 (edited) Thanks for the details and the link. I didn't know there was a four pinion open option. More knowledge. I'm going to assume you can do more one wheel burnouts with a four-pinion than a two-pinion. Four is better than two.

guns Posted February 6, 2014 Author Share Posted February 6, 2014 Thanks for the help guys was hoping it was a aftermarket LSD but look like I am going to have to keep looking Quote Link to comment Share on other sites More sharing options...
