NewZed Posted April 23, 2014 Share Posted April 23, 2014 Can you unwrap them all completely and take more pictures? The first one is different-looking. They all seem to have the general R200 shape. Quote Link to comment Share on other sites More sharing options...
z240 Posted April 23, 2014 Share Posted April 23, 2014 (edited) Pics 2, 3 and 4 are generic R200 diffs. As suggested, unwrap more to make sure they are long nose. The first one is definitely not a Z diff, an interesting mystery that someone will have to solve. You will be asked for more pictures of it from several angles. Please post soon as the suspense is killing me. The overall configuration makes it look like a relatively 'easy' fab job to get into a Z compared to some recent swaps we've seen here.

AkRev Posted April 23, 2014 Share Posted April 23, 2014 (edited) The first picture looks like a Supra LSD. Edited April 23, 2014 by AkRev Quote Link to comment Share on other sites More sharing options...

NewZed Posted April 23, 2014 Share Posted April 23, 2014 Looks like two long-nose R200's at least, and a good match for AkRev's Supra diff on the odd one. The R200's will fit a Z. The Supra diff looks interesting, considering the work that people do to fabricate CV shafts and mounting hardware for the shortnose R200's anyway. I wonder if the Supra diffs are any easier to find than the 300ZX clutch types. The Supra's a clutch type I assume, since it requires LSD oil. It has short side flanges, which should fit inside the transverse links ( control arms) better than the big VLSD flanges. Quote Link to comment Share on other sites More sharing options...

Do I have to open up and look in side? Thanks Quote Link to comment Share on other sites More sharing options...
NewZed Posted April 23, 2014 Share Posted April 23, 2014 One of them is labeled 3.55. Probably 3.54, depends on your rounding method. Common ratios are 3.36, 3.54, 3.7 and 3.9. Look for more numbers. Or, mark the flanges, spin, and count. Quote Link to comment Share on other sites More sharing options...
