Ok time has come to post this since the VLSD faq and install info on 240sx.org are old and outdated.
So here we go .
What works what doesn't and so forth.

First we deal with history. Our differentials are R200's a differential Nissan has been building in one form or another since the early 80's . Yes you can find them in 280zx's but who would want one ? The casing was slightly different it has to many miles and the input and output shafts are different.
That out of the way on to the more pertinent stuff.
VLSD's Now there is a few different opinions out there as to when Nissan first officially put these babys in our cars. This is Nissans fault . When our cars first came out Nissan was still in the process of converting all there files over from microfiche to computer here in the states.
For the record the Nissan official line on this is VLSD's were offered as an option from 8/90 forward i.e. 91 model year. Now they came installed on the car with the Hicas option. You could order them though as a dealer option and were offered from some dealers in what was called a tow package. Most of the time cars that came with VLSD's quite often also had the ABS option. Some 5 speed LE's came with the ABS VLSD package . Our own S13grl owns one of these cars.
On S14's VLSD's were sold as options on the SE models but just because it was an SE model did not mean it had a VLSD same goes with S13 ABS cars.

That out of the way gearing for the American version of the Nissan factory VLSD in S13's and S14's is 4.08.
Now on to the more interesting stuff which other American Nissans equipped with VLSD's will work in our cars.

300zx Turbo will not work to large!
300zx NA will work has the same gears as our cars but you need to either get pre 95 J30 5 bolt axles to bolt them into our cars . Or try to order the forever back ordered 240sx VLSD output shafts to replace the 300zx VLSD output shafts. I recommend the J30 route its a lot cheaper with less down time.
Infinity Q45 this one has 3:70 gears and a larger input flange so your driveshaft would not mate up with it.
Ifinity M20 will not work different pumpkin.
Infinity J30 pre 95 3:92 gears will work as long as you use the axles from the J30 as well.
Infinity J30 95 and up 3:92 gears will bolt in do not need to use the J30 aaxles.
Now on the J30 differentials the ABS sensor is located at the front of the differential. This makes a 1/2 difference in driveshaft lengths on cars that did not come with ABS those that did are good to go.
Some people have installed these without shortening there driveshafts. They basically compress there center support bearing on S14's. On S13's the center support bearing is on the front half of the driveshaft.So you cannot do that .
There is word on the net there is a way to make these work without shortening the driveshaft or compressing the center support bushing but I have not seen actual proof of this as of yet.
This can actually be a good time to get a single piece aluminum driveshaft made and actually save about 15lbs of inertial drag weight on your drivetrain thereby freeing up HP.

Thats it in a Nutshell folks , have a good night


may the drift be with you
