WOOT! VLSD installed. Slight review/bitch session inside.

[Jeff240sx]

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!

damn VLSDs! Hope yours lives longer than mine. I should have just bought a real diff instead. Planning on that next actually. Hate vlsd. Lock when it wants, ...trying to drift, no lock, almost out of drift, LOCK! WTF!?!?

have fun

[Doriftomodachi]

Meh, VLSD = nothing to get excited about compared to a clutch type LSD. Like nightwalker said VLSD's also wear out in time and become an open diff so you are back to square one. You should have saved the extra $$$ and got a clutch type LSD. You might not agree now but once you drive a car with a clutch type LSD you WILL want one.

[TheSnail]

Thats a bit harsh. Im not into the whole drifting thing, but my vlsd serves me great for the past 3 years. I think thats why the world created it. But then again all those engineers dont know how much better a cluch type is, or do they???

[nightwalker]

clutch lsd is not for your everyday joe. Plus, makes the price of the car more.

[mrmephistopheles]

He's got a HLSD that'll be on the way soon enough.

[ghostuss]

my Vlsd won't lock in wet ... :cry: I went to a drift event in rain and it is nothing but a bunch understeers while in rain. Got a bunch 4 wheel slide going out but damn no rear end swaying. Once it got dried around noon time, Party time!! Start to lock and kickout and spinning out :Ownedd: I guess it's cool since you won't want the lsd to lock anyway in slippery conditions. :coolugh:

Just get a welded diff.

[Jeff240sx]

The 300zx vlsd has a lower breakaway torque. While the 240sx is 70ft/lbs, the 300zx is 45ft/lbs. It doesn't seem like much, but it is. The 300zx wants to lock nearly instantly, while the 240sx unit won't let my friend's NA 240 launch at the rpm my car will.

Jeff,

is this a 300ZX NA or 300ZX TT diff?

Thanks!

[Jeff240sx]

NA. The TT diff is an R230, won't fit in our carrier/pumpkin, and it's carrier won't fit in our subframe. I've been thinking about stuffing a z32 subframe in a s13, and inserting the 300zx TT diff. That, would be badass.

Don't forget the badass GReddy-style rear diff cover with cooling fins, that come with the 300zx unit. I'm so incredibly happy with my vlsd.
-Jeff

[nightwalker]

I don't know which diff I got, because it was bought from a shop that didn't know either. But my pumpkin has the lower rear extrusion for more fliud and the multiple cooling fins running almost the entire cover from top to bottom, and side to side.

still sucks

[Jeff240sx]

It was sarcasm. I wouldn't pay as much for a GReedy diff cover as I did for the diff. I think it's a worthless investment for 90% of people.
And if it sucks, get a new one. For me, I drag/street race, and take corners like a champ. I don't want a noisy mechanical deal, and my vlsd has made me a happy camper, after 4 years, 2 turbocharged years of peg-legging.

whatever makes you happy.
