johntlr1000 Posted March 17, 2011 Share #1 Posted March 17, 2011 Just bought a 78 280z 5 speed car. How can I tell if it has an r200? or did they all? Link to comment Share on other sites More sharing options...
Zed Head Posted March 17, 2011 Share #2 Posted March 17, 2011 Compare it to your 240's. The R200 is bigger and rounded on the bottom, vs. the squarish look of the R180. If you search this forum for "R200" and "R180" you'll probably find some pictures also. It's probably an R200 unless the car started life as an automatic.

spitz17 Posted March 17, 2011 Share #3 Posted March 17, 2011 On an R200, the transverse link cross member that you will see by looking at the differential when kneeling behind your car will have a natural bend towards you. If it is completely straight, it's an R180. Link to comment Share on other sites More sharing options...
cygnusx1 Posted March 17, 2011 Share #4 Posted March 17, 2011 MT 280's all came with R200's. Some ratio variations exist depending on configuration. Link to comment Share on other sites More sharing options...

If it is completely straight, it's an R180.Not true. Only the 70 and 71 were straight. After that they moved the diff back and used the curved link so that they could fix the U-joint angles.

tymarbry Posted March 18, 2011 Share #9 Posted March 18, 2011 Also I might be late on theis but if you look into you FSM using you VIN it will tell you 100% what you got for a Diff.I would say its probably a R200 also. Link to comment Share on other sites More sharing options...
