Hey guys if someone could help me that would be great. i found a 87 Nissan Pintara and was wondering if these were fitted with a H165?

No.

They run a Borgwarner (25 spline axels, 4.11:1 ratio) rear end. Too wide.

What's the H165?

Is that the R31 Skyline diff.... 28 spline axle's LSD opton etc.

Coops, the tech section. . .

H165, 1200 ute and series 1&2 Bluebirds. No doubt in other models also. Live axle 180B and 200b?????

Yep R31 SKYLINE is the 28 spline.

What I really want to know is what the R31 skyline diff code / part no is?

Anyone? H***??

correct me if I'm wrong but the skyline and other nissan independant rear end diffs have the "R" designation. for example R200 long nose and short nose etc

No Idea.... All I know is that they're Borg Warner items & the same as what they put under the VL Turbo Commodore.

I'm trying to find out what the part no is so I can find a LSD centre to suit.

Dont know a part number but do know that the borgwarner has been exactly the same for many years. Apart from the obvious.
They came in many differnt ratios and and were basically either 25spline or 28spline.

Cars off the top of my head that have them-
Xf falcons (???splines)
Pintaras (25spline)
Skylines (not too sure but i believe 28)
VL commodore up to VS utes which still run a live rear end. Vl N/A were only 25spline whilst the turbo was 28spline and then from VN all the way to VS utes are 28spline.

Thats all i know. Dont know if the indepent rear centres are the same and dont know whats under the new tunners.

BTW. Coops my mate has a complete disc to disc 28spline LSD out of a VN he is willing to sell if your interested. Cheap as it has a bent axle tube. Good centre though.

Quote:

I already have a (shortened) 28 spline R31 diff.
What I'm looking for is a LSD centre to convert into my open centre diff into a limited slip item.

Do you think he'd be willing to sell just the centre?

He probably would sell just the centre or the whole thing for the price of just the centre just to get it out of his backyard.
