With my newfound suspension, tierods on the way, I've just installed a vlsd.

50k mile unit from a 300zx with ABS. Using the milled open output shaft and the other shaft, it's wonderful.

Before:
1500rpm slip = launch.
1800rpm slip = smoke show.

After:
4500rpm slip = launch. hard.
5000rpm dump = HAHAHAHA! Sorry about your parking lot Publix.

Install:
Sucked ass. 5 hours.
The first 30 mintues was dropping the old open-diff. Followed by attempting to remove the 300zx driveshaft bit that was left on by the salvage yard, because they saw-zall'd it off. No go. The crescent wrench kept stripping the nut. So after like 30 minutes of dicking with that, we busted out the Dremel and tried to cutoff-wheel the nut and bolt stud. After getting like 1/2 way through one bolt, I figured I would get the torque I needed if the lsd was bolted to the axles, rather than my buddy trying to hold the output shafts. So I installed the lsd, and it didn't feel like budging. Hour 2 is rolling up, and it's back out with the carrier. On the ground, and now I'm pissed. Dremel out, and just going to town on the nuts. When I get 1/2 way through all four nuts, it's hour 3.5, and my dremel shaft is rubbing, because they are tiny cutoff wheels. After thinking, I grab a tire iron, and cram it through the 300zx differential bit, which happens to be a U-joint. So then 3 bolts undo, and the fourth stud breaks. HOORAY! Back up into the car, and after a total of 4.5 hours later I'm done. Followed by a 30 minute cleanup, it's off to the parking lot!
Yay for me!

Hey, how do those cut output shafts work? I'm going to install my vlsd that way too since I'm too poor to find outputs. What did you use to cut it? Isn't the ABS vlsd like 3/4 in longer than a non abs equipped 240? What did you do? That's kool, I just wonder how my j30 will work with the taller gear ratio...

You just nip the tip. It won't stay in the lsd because the c-clip won't hold, but the axle holds the output shaft in place. Take it to a machine shop, don't use a hacksaw.
And the ABS 300zx unit was the same length as my non-abs 240 unit. While the 240 open diff has a 1" space between the driveshaft mate and the carrier, the 300zx unit has a 1/2" in space, and 1/2" for the ABS crap. It was the perfect length.

So I'm curious on this.
I was looking to buy an R200v VLSD diff out of an S13. but it is just the diff by itself.
Thing is, I have an open diff right now.

will the output shafts fit from S13 R200 open diff to an S13 R200v VLSD diff?

 

pretty sure they will, yup

 

Why do you say this? I've always heard the contrary.
-Jeff

 

no they wont

 

Mis-read your question..... yeah... what the Ostrich said

 

So where can I pick up some 6bolt vlsd shafts?
