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

[«Cyph3r»]

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^?

Yes. I don't think you have 6 bolt GTR stub axles....I think they still used 5 bolt Skyline axles. So just getting a suitable generic Skyline diff will do the job. And probably/possibly a tailshaft, as you said.

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 But now... Nice tight GTR Rear end perfection, locks up nicely with a freshly rebuilt Nismo lsd disc kit in the 1.5 center

R230 or R200? R230 is Z32 diff.
