S12 R200= longnose R200
S13 R200= shortnose R200

To get an LSD for the R200 longnose, you will need an S13 LSD designed for an S13 OPEN DIFF CASE AND OPEN DIFF INPUT SHAFTS. The S13 open diffs use equal length shafts on both sides, which have the same spline count(29) and length as an S12 half-shafts.
 
You cannot use OEM VLSD diff unless you use the VSLD input shafts. If use the VLSD shafts, you'd have to make new half-shafts for it to work with the S12 arms. You could maybe use the Z31 VLSD shafts, but those are rare in itself and you'd have more trouble finding those shafts than the Z31 VLSD.

The VLSD uses unequal length input shafts(one side is longer than the other) because that is how the VLSD works. So if you get an S13/S14/J30/whatever VLSD or an LSD designed for an LSD case/LSD differential/LSD input shafts, it WILL NOT WORK WITHOUT CUSTOM HALF SHAFTS. This also includes the S15 HLSD with 30 spline count, because you would have to use those input shafts.

Thank you sir

So am I correct that the VG30E cars all came with 3.90 gears?

Thanks!

How does the R200 differ from the R200V found in the limited slip diffs in S13/J30 chassis besides the obvious viscous limited slip part. Physically how are they different if at all?

I believe they have a longer snout than the J30 and the S13 rear ends, and so the pinion gear would be different. If I'm putting it the right way. Brewster knows something about Infiniti components, maybe he can chime in and verify or correct me if I'm wrong.

I know that the ABS model S13 has a longer snout as opposed to the non. I wonder if the non ABS diff will fit?

the non- vlsd differential will fit the s12 diff housing.

the housing, and ring and pinion are different, as well as the output shafts.

What you guys don't really know is which R200s have the 10mm bolts and the 12mm bolts. Or maybe it's just me. haha Anyway thanks to the Z31P member for this image. Supposedly he has the full program for searching up nissan part numbers and whatnot.

well the difference with the open vrs. vlsd differentials is the output shafts.

Hello! May I, even though I'm new,suggest to add some R180 info on the first post also, browsing around I found so much misinformation about it and got really confused.

The info that would be cool to post is the R180 LSD options, such as the old Zs and the Subarus that have this same diff. I KNOW I can find it searching but as I said, while searching probably 80% of what I found was wrong and/or incomplete and/or just guesses.

So does it matter what R200 differential ratio I get with my CA18DET powered 200sx?  I have options of:

4.11:1

3.90:1

and 3.545:1

From what I can tell the 4.11:1 would give me better acceleration, burnouts, and drifting, and the 3.90:1 and 3.545:1 would give me progressively better fuel economy, and conversly, progressively weakened acceleration.

Can someone fill me in?  Thanks!

It is 100% sure that I can use the s12 opencase for S13 LSD opencase?

S13 LSD designed for S13 open case[/u] will also fit in S12 case.

Make sense?
