What Diff Housing Required To Swap Out A-Lsd For Mechanical

Hi,

I have a series 2 R33 GTS-T which has the optional A-LSD fitted. I would like to remove this as I have an ATS 1.5way Centre for an R200 to run.

Only drama is I don't know what Diff housing/casing I need to swap into the car.

Anyone done this before?

Do I need a GTR diff housing?

A-LSD measures roughly 350mm from driveshaft flange to driveshaft flange and approx 350mm from tailshaft flange to splitline where the backing plate bolts on.

(Very rough measurements taken under the car in the dark in a rush)

Thanks

Jamie

Also does anyone know if the A-LSD specced GTS-T's have the same tailshaft length as the viscous equipped cars. I'm guessing it has to be shorter seeing as the diff is longer?

Thought about it some more. GTR driveshafts are different spline count front memory. This means the either they ran GTR hubs in the GTST uprights (highly unlikely) or the run GTST driveshafts bolted to the stub axle. So in that case it would be more likely I need a GTST viscous diff and half shafts and a normal GTST tailshaft which I'm guessing makes up the difference in length between the GTR diff and GTST diff.

Am I onto the right idea here^?

I went from A-LSD to a Non Vspec R230 diff and it was one hell of a headf&%k... Ended up using the A-LSD Tailshaft Flange in the New Diff, and GTR 6 bolt Half Shafts because luckily I had access to GTR Drive Shafts as well. Then because of the GTR Driveshaft splines being fatter than the GTST ones, I had to swap my wheel hubs for GTR ones as well.

Very annoying few days of working on it :P But now... Nice tight GTR Rear end perfection, locks up nicely with a freshly rebuilt Nismo lsd disc kit in the 1.5 center

      No. I think it's gone. 😭 I think you can get body coloured ones on eBay so I think I'll get one of those... Or just hang a red ribbon from the hole and whack a TOW sticker next to it.

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.

      Probably a smart choice to buy one vs build, purely for the motivation part as you said! Imagine the metal dust everywhere from grinding all the steel to build one. Ha ha ha!   Also, post a photo of your garage.   Mine is below, this is where I've been cleaning and have already half filled a caged 6*4 trailer. And this is after my cleaning expedition mentioned previously... The middle normally has a car in it, but I'm dumping things in the middle as I sort through them. And poor skyline was dusty and has had the lightest few drops of rain and now it looks atrocious and needs to be dragged back out and washed thoroughly! And yes to the right is technically another bay, you really can only see 2 bays out of 3 in this picture.
