What Rear End Is This?

[nissan200sx.dk]

Hi.

The right rear end.. From what car is it? I am very confused about it. It shuld be from an R32 GTR.

But on the disc it says RB25... Hand written. Like a tag.

Diff ratio, if turning on the diff side, i get ~3,6 revolution on the wheel.

Hope someone can help me, as in building 4wd on my s13, and need to be sure the front and rear diff ratios are the same.

Hope to get some quick help as om going to buy the front stuff tommorrow...

Thanks

Looks absolutely like an R32 era rear end. The upper arms definitely. 6 bolt half shafts and CV joint type tailshaft connection make it a GTR diff. Also has ABS, whish wasn't so common on other non-GTR R32 era stuff.

3.6 diff ratio is not right. GTRs are 4.11. Could have had a different centre put in it.

The diff ratio is 3.6....

The way I meassure diff ratio is by putting marks on shafts and turning either the disc, or the input shaft on the diff.. I get the same result of 3,6 ratio.

The 4,11 is not a final drive ratio?

But thank you very much for the reply.

Is this way of measuring very wrong?

Will the LSD not lock enough to turn both sides equal?

after digging arouind I think it is from a 300zx... Same ratio, and also the GTR has the servo lines for HICAS that goes under the diff, not over as mine does.

You should be able to tell if it's from a Z32. The diff is an R230, which is noticeably larger than the R200 from Skylines and GTRs. I don't know about the diff ratio for theZ32, but because it was a bigger engine it could easily have used a taller ratio, and 3.6 would be a good choice.

The best way to check your diff ratio is to pull the rear cover of the diff and look at the Ratio stamped on the crown wheel, its the only way to get it right and so easy to do m8, Jamind

The house is a little bigger than the skyline diff I got now. I have made a diff swap, so now the rear end has the correct diff ratio, so I can get on with the 4wd build.
