Which Nissans used same differential?

[Rollie715]

I heard somewhere that Nissan and Subaru have the same parent company and in fact the front differential from a Nissan 4x4 IFS is the same as the rear diff in the Subaru. If that is even close, I'm thinking of finding one of those Nissans, take out the front diff, axles and hubs and fabricating something to make them fit into the rear of my 88 GL Wagon. Then if I can put on some lockout hubs, I will weld up the diff and shift the lockouts into freewheel when driving down the road.

 

I may also have to deal with gear ratios while I'm at it.

 

My question for you all, is what years and models of Nissans if any would have the front axle parts I am looking for?

Subaru and Nissan don't share a parent company and never did. Nissan used to own a majority share in Fuji H.I. just like GM did until recently. But to answer your question, early Z cars and early 510s used R160 rear differentials. I know there are more, but these are the only ones I know of for sure. Our differentials are an upgrade to the original Nissan ones because ours have LSDs.

R-180: 720 4x4 1/83-6/83 nissan pick up has the 3.9 ratio.

heres a list of them all maybe

Mind you if a R180 fits then a R200 will fit (might have to mess with the mustache bar) If anyone is interested, ill do a spline count on an r200, just let me know

 

280z and 280zx's have R200's it's a much beefier diff, their ratio's are 3.54, 3.7, 3.9 stay away from the 1975 year they are wierd and the diff may not adapt well.

 

300zx 84-89 have R200's with lsd but their ratio is only 3.7, swap gears from a 280z. You get a 3.9 with lsd and an indestructable diff. (not all are lsd look for a finned cover!) The idea of this would be to run 300zx axles, thus less axle breakage! But it is only an idea,

 

goodluck with the path you choose.

Clutch type. R200a diffs are supposed to also fit R200. Purenissan

If you're rich, you could also put an air locker in a R200.

OK, What I'm hearing is the possibility of there being a differential out there out of a Nissan that could bolt into my Subaru with minor changes, that would also have available a 3rd party locker. I'm not rich, but buying a locker would be way easier then going the route of fabricating some kind of selectable lockout hub setup.

 

So how close to our original diff is the R200 or R200A? Do they bolt right in? Do they have the same driveshaft and axle splines?

 

I'm really interested in pursuing this idea.

 

Thanks for all your input,

I need some clarification. What rear diff is in my 88 GL Wagon and are there other Nissan diffs that would easily fit and have the same driveshaft and axle splines?

 

I've been doing some searching on the internet and found lots of reference to Lockers in R180's. Do we have R180s? Will an R180 fit?

 

The bottom line, is how can I get a locker in the rear of my Sube without welding it up solid?

 

Thanks again

You have a R160 diff.

R180's should be compatible, the spline count is 25 (have one on my desk) the drive shaft flange looks like it will work on any of the diffs 160,180,200

if the gears are 3.9 then it should work. the ideal way to lock the rear would be to put an r200 in and weld it up and switch to 300zx rear components.

an er27 couldn't break it. but thats my .02
