Diff Question

[XTC 190]

Hi all, I am after info on a R31 Skyline Silhouette, what type of diff is used in these cars, I have been told elsewhere that they are a Borgwarner M78 diff 28 spline is this correct or are they different.

I am looking to buy one for a project but need to confirm theses details, the one I am looking at is a LSD.

Thanks for any help given

I need to confirm if they are 4 pin or only 2 pinion as well

Thanks

Hey mate, I have no idea...however have you tried posting/asking on the r31skylineclub forums?

Might get your answer a lil quicker than here mate, sorry bout that!

if it has drum brakes it is a borg warner 25 spline. if it has disc brakes chances are its probably 28 spline unless someone has done a brake conversion on it. the lsds are 4 pin whereas open centres i think are 2 pin

What about a R32 skyline diff what are they are they borg warner m78 28 spline 4 pin LSd and ratios are they 4:11's

[2BNVS]

should be 28 spline as pintara's are 25.. they are also lsd on the silhouette...heard they arent that much better.. i just put a mini spool in mine lol

Sorry for all the noob questions but as this is going into a different make of car I need to be sure of details

Can I clarify

R31 diffs = Borg warner m78 style Lsd 4 pinion 28 spline

R32 diffs = Borg warner m78 style Lsd 4 pinion 28 spline

R33 diffs = ?

And what ratios can I get in these 3 style diff?

In regards to a car that will max out at 250rwhp what is the stronger?

I have seen mention of the r33 having 4.4 ratio gear set, are these beneficial to the Drags compared to say 3.9 r 4.11's?

Again I apoligise for the questions but you guys on here have got a lot of good knowledge so thanks for any help received.

lsd is 4 pin ion with 28 splin axels dont know about the open wheel diffs which ive seen a few silos come with seeing there 20 od years old and the lsd is very weak

i dont think 32's have borg warner diffs. correct me if i'm wrong

[bubba]

No they don't, R32's have an R200 and an IRS setup, aust. delivered 31's are a solid axle setup.

Don't know if the diffs are BorgWarner based but I doubt it..
