CU Zcar Posted January 13, 2003 Share Posted January 13, 2003 Does the 3.9 (?) R200 in a 1983 280ZX Turbo have 10mm or 12mm bolt holes in the ring gear? I ask cause I have a LSD 300ZXT differential with something wrong, and possibly a differential from a 280ZXT. I could just swap center sections if I can't fix the 300ZX diff, if the bolt holes are 12mm, couldn't I? Quote Link to comment Share on other sites More sharing options...
Dp351zcar Posted January 13, 2003 Share Posted January 13, 2003 The bolt size on a 83 is 10mm. It dosn't change until 87 after that it is 12mm. I think. I know 83s are 10mm because I have one. Don Quote Link to comment Share on other sites More sharing options...

CU Zcar Posted January 13, 2003 Author Share Posted January 13, 2003 Well damn! Guess I'll continue looking into what's wrong with mine. Or else find a 200SX 4.11 R200 to swap the LSD into... Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted January 13, 2003 Share Posted January 13, 2003 Originally posted by CU Zcar:Well damn! Not so quick........the ring bolts thread into the ring gear and prior to that they pass thru the carrier.........so if ring gear takes 10mm bolts.......just make (or send me specs, I'll make them easily enough) bushings of appropriate material and size to bush the 12mm holes in your 12mm carrier. I've intended to make these for some time but noone's seemed to need them yet. PS most 4.11 R200 200SX units are 10mm as well IME. Quote Link to comment Share on other sites More sharing options...

zcarnut Posted January 13, 2003 Share Posted January 13, 2003 According to Nissan all the turbo Z31 R200's used 12mm diameter ring gear bolts, not just the '87 (and later) LSD diff's. Quote Link to comment Share on other sites More sharing options...
