rb25 lsd differential ratio?

Hi

I find a lsd diff from a skyline with rb25det!
Can you tell me please with what ratios nissan produced this?
The lsd I find maybe was from a japan skyline!

Is it viscous lsd like 200sx?

Get these confirmed but I think the Manual is 4.11:1 and Auto is 4.3:1

Manual is indeed 4.11.

Auto is 4.363 to be a pedantic pain in the posterior

is it possible to fit the lower ratio auto diff on the manual gtst r33 ? i was wanting to lower my gears a bit and this would be ideal if it fits...

Well i kept the auto diff when i had an auto to manual conversion done.
Top end suffers by 10-15mph.

I dont mind losing 10 to 15mph top end, I prefer acceleration.... This is something I will certainly be wanting to do.

The abs sensor is fitted to the front of the diff as well. So if you have abs and want to keep it you'll need an auto diff with this sensor.

Abs and non abs diffs have identical mounts/fittings/dimensions etc

No ABS on mine so no problem there, I take it i can use either abs or non abs diff in my case.
