Skyline Diff In A E36 Coupe Anyone Tried

[Bsa]

Hey guys and girls I'm at the point where my rb26 BMW is almost ready to go I'm worried the diff will shit itself. So to add a bit of reliability to the drive train I want to install a gtr mechanical LSD now from playing with lots of skylines and sussing out the BMW rear I know it won't be a bolt in solution I have a ideas of how to do it but wondering if anyone has any ideas how to go about this

[GTSBoy]

Wouldn't it be easier just to find a strong BMW diff?

[Bsa]

They just have a shitty ratio they are also very expensive also a strange housing size and to top it they are very hard to find in a LSD

[Stevoss]

custom drive shaft and cv's then mounting the to the subframe, work cut out for you but since you can fabricate then go nuts.

A supra ma70 will go in without too much drama, they are narrower than the r200.

If you run the 6 cylinder axles, theres just enough room to make axle adapters to the ma diff

I looked at the r200 into mine but they are just too wide / about 340mm vs 260mm

Thanks mate I'll look into it I'll just run the 4.44 ratio it's got now till I figure out what I'm doing

To help you search for Supra diffs

Early 3L Non Turbo - 4.30 LSD

Early 3L turbo manual - 3.91 LSD

Later 3L turbo auto - 3.73 LSD

Early 2L Turbo 4.5:1 open for both auto and manual I believe

2.5L Twin Turbo R manual trans 4.11:1 Torsen center

2.5L Twin Turbo R Auto 3.9:1 Torsen centre

Also B series JZA80 (late model) diff centres allegedly fit inside the MA70/JZA70 diff housing, which can be had in 3.20:1 up to around 3.60:1

Thanks mate don't know much about supras the 4.11.1 diff is around the ratio I wanted. Quick question what's a torsion diff like can't say iv used one

[zebra]

Just a different type of LSD

I should add that they can be a bit of a pain with big power

as it spins one wheel, then the other, and repeat (was a big problem with some of the older HSV's that had them, I can say I have noticed it with my car though

[Bsa]

Hmm I really don't want that at all

[GTSBoy]

Horses for courses. Helical (Torsen) diffs feel excellent on the road. Smooth, repeatable, consistent behaviour. Any tendency to shuffle drive from one side to the other with big power could probably be dealt with with some adjustable dampers. I just put an S15 centre (it's helical) into my R32 and it's wonderful.

[Bsa]

Is there any chance I could do the same thing but into a BMW housing

[GTSBoy]

Wouldn't think so. But you could possibly buy a Quaife centre, or some other torsen.

[zebra]

A quick google says some of the Z3's used torsen diffs

maybe interchangeable?

[Bsa]

Yeah I found that but finding one is impossible I can get the m3 diff but unsure of condition still turns nice but has been sitting there for 5 years now

i know its prob not going to sit well with some of the guys on this forum, but i have seen a conversion done on a 3 series BMW using an IRS commodore diff. it was fairly straight forward apparently, but i would make sure to research it. its not a bad idea as theres alot of ratios available and lots of options for centres LSD's, detroit lockers, spools etc.
