bigjim5551212 Posted March 6, 2004 Share Posted March 6, 2004 Has anyone looked at the Nissan differentials, out of old 510's, Z cars, 240SX, to see if they bolt up to a Subaru or the other way around? Quote Link to comment Share on other sites More sharing options...
calebz Posted March 6, 2004 Share Posted March 6, 2004 Lots of the datsun guys buy our LSDs for their 510s and older Z cars..If you see a soob LSD on Ebay selling for 4 times more than its worth, its because the datsun guys are bidding on it.

bigjim5551212 Posted March 6, 2004 Author Share Posted March 6, 2004 a datsun diff has flanges with 4 studs on it. The axle bolts on to the flange. Only cars that dont have this is diesel maximas, 1974 260Z and turbo ZX Quote Link to comment Share on other sites More sharing options...
Mike W Posted March 6, 2004 Share Posted March 6, 2004 Given that 510s had open diffs I can't imagine why we'd want to use a datsun diff. Subaru Brat is apparently going with R180 diffs for his beast. That diff has bigger stub axles and I belive you can either use Nissan axles or Subaru STI axles with it. If you were to use unmodified STI axles it would require STI or SVX wheelbearings to accomodate the big outboard stub axle. I think Subaru Brat was going to splice the inboard STI axle onto beefed up EA81 outboard axle stubs. The R200a diff weighs 26lbs more than our R160 but it's supposedly bombproof up to 300+hp and 31" wheels with lockers. It looks basically like our R160 but it's bigger and burlier. The shorter body R200 can supposedly use the same clutch type LSD or ARB air locker as the R200a but might weigh a few pounds less due to the shorter body. Both of the R200 diffs would require custom mounting. Various ratios are available but I think Pathfinders had the lowest. Quote Link to comment Share on other sites More sharing options...

Yup. Their diffy has flange outputs, while ours uses stubs... so they change 'em over to flanges to use our LSDs. But really no point in going the other way, since we're the ones with the desirable LSD anyway. There's an page describing the swap, ill see if i can find it.

Mike W Posted March 6, 2004 Share Posted March 6, 2004 Here's a pic of a R200 from a 240z. They're used in a number of other Nissans and Infinity. Big heavy suckers yes, but they're stout. There's lots of info on the net, try searching for "R180" "R200a Nissan" and "R200 Nissan". Quote Link to comment Share on other sites More sharing options...

Mike W Posted March 6, 2004 Share Posted March 6, 2004 Yeah SK as far as I know, Datsun 510 diffs are the same unit we have on our old Subes. I'm not sure just offhand what ratio they came with. Sorry for spewing out all the irrelevant info, I thought was what Bigjim was asking about. Quote Link to comment Share on other sites More sharing options...
