[Nismochick240]

I searched and didn't find the answer to my question! What 240's have stock LSDs? is it all of them?

[PantherRacer]

The ones that were sold to drug dealers maybe?I'm sorry, I'm not helping

[Nismochick240]

usually those are so old they start acting like open differentials. like my hicas.

[skydragoness]

^ Yeah, that's true. It's hard to say since some are in better shape than others, I got a VLSD from an S14 off of ebay, but everyone was clamoring and sniper-bidding for the S13 VLSD, i have no idea why. I would personally try to get something newer.

You know what I don't understand? Why the hell does Nissan charge almost $1500+ for an outdated VLSD pumpkin but charge $700 for a Nismo clutch drop-in unit and around the same amount for a much better Helical? They can't say it's because the VLSD's aren't common and there's less stock of them because many of their current vehicles today still use vicous units.

i don't question nissan's pricing scheme. it makes my head hurt too much.

i managed to get ahold of the guts of an S13 silvia k's VLSD for around $150. The thing is in perfect shape and only had like 80k km on it. I think nobody was bidding on it because it had to be shipped from japan for a pretty penny.

all in all, I plan to upgrade to a helical unit in the future (when i actually have money to spend again).

Also, please don't call anyone retards on the boards. Some people will be less likely to respond, and the likeliness of the thread finding it's way to the netherworld are much higher.

^haha. yeah it does make my head hurt. my bf and i were quite perplexed about the pricing scheme for the nismo unit, helical unit and the viscous coupling.

I'd LOVE to upgrade to a helical (s14 vlsd getting put in today, yay!) but nowadays people are raping others for them. Some guy on ebay selling the unit, and albeit he's including the output shafts but he's asking $689 buy-it-now price. That's INSANE. I could've sworn by my frog socks that people in Japan were selling them starting at $60-80 and $60 or something to ship. At least that's what i remember from a couple of years ago.

[spider_slayer]

weren't vlsd's and anti-lock brakes sold as a package on the usdm 240's?

yes. sky already stated that earlier. sometimes the prices of a JDM unit are good enough that you take it over sourcing a USDM unit. I bought mine from a silvia because it was such a good deal. All said and done, i paid around $300 with shipping included. All I needed was to source some output shafts. $90 later I had stubbies and an extra set of axles out of a CA powered silvia.

my most favorite nissan price is for the "nissan" logo that goes on my B-pillar. It's barely 4 inches across and 2 inches high and the dealer wants $75 for it. Yet I managed to get a Silvia logo for the rear trunk garnish from the same dealer out of the Nismo catalogue for $20. Go figure

[Nismochick240]

mm sky thanks you've been a lot of help

[JimmyMethod]

I've looked at the article, but I don't quite get all the requirements for a VLSD swap from a Z32 or a J30. So, you need the VLSD...and the housing...output shafts from what?Drivetrains get me so lost...

[574-240sx]

Simple as this, a N/A Z32 diff and J30 diff will bolt into a S14, you would have to swap rear cover to make it bolt into a S13. Some diffs have the 5 star pattern on the output shafts and you will need to use J30 axels to make this work. The 3x2 bolt pattern on the output shafts will bolt to stock 240sx axels.

[skydragoness]

Hahha. Guess what guys, my s14 vlsd was finally put in last night, and it started to rain its a$$ off too. So some BG LSD additive and new diff fluid was added in and my bf took it down from the lift and put a decent short pair of 11's down on the Nissan garage pavement. Once I drove my car out of the garage I could already tell the difference, it still needs an alignment so i'm going back this evening for that. I already feel more confident in the rain, but then again my tires kick a$$ in the wet.

[SimpleEnigma]

So I could find a what year J30 diff, put my stock open differential rear cover on it, and it will drop right in, stock axles and everything?

[drifter_for_life06]

havent a few peopel on these boards gotten "lucky" and had non hicas or non abs models and found themselves with an LSD?

maybe not but i thought i remember that from a while back

I found these links extremely helpful, SimpleEnigma, in addition to the ones Sky posted in the beginning of the thread.

I went with a JDM unit as well because I found a 91 r32(RWD model) vlsd with axles no one was bidding on. $323 shipped to my door last friday.

Unfortunately, it started snowing today. With more to come. So I think my car will be coming off the road and apart for the winter. I already opened up the VLSD, and it doesn't look beat on. Output shafts are VERY hard to turn by hand in opposite directions.

Is it recommended to put the LSD additives in for viscous differentials, Skydragoness? I wasn't sure.

You can't put regular diff fluid in there if that's what you mean. Since I had mine installed at Nissan (sidejob) they don't have 'lsd' fluid, what they do is add in some BG LSD goop into the diff, then fill it up with the regular diff fluid.

Are you sure that different fluid is neccesary? Everybody has told me that since the viscous coupling is a sealed unit, that no special fluid is neccesary. I have never heard of anyone adding anything other than typical diff fluid to a VLSD.

[skydragoness]

^ It's what they [the techs at Nissan ] have to put in the 350z, which uses a VLSD, i think those people you are referring to are wrong. I think it has to do with the fact that they generate heat so they need something added in with the regular diff fluid.

[naed240sx]

hmm. Well I have regular diff fluid in mine. It worked great for the first week, and started to die on my afterwards. Could the fluid be the problem? Anybody else have input on this?

[skydragoness]

^ Yeah, you never mentioned that in your other thread about your diff dying. Don't know for sure if that's the reason, but i wouldn't doubt it.

Redline has fluid for "special rear-drive racing differentials" I also found this stuff which may help http://www.redlineoil.com/prod...ID=20

Ah! That's kind of exactly the same stuff Nissan uses in the BG brand.

[naed240sx]

See, but that is for clutch diffs.

"Limited slip or positraction units will often chatter without use of this product or a gear oil with a similar modifier, so add only enough to eliminate the chatter and avoid making the plates or clutches too slippery."

The clutch plates in diffs such as kaaz and nismo are exposed to the fluid, and require a special kind. Unless I am very mistaken, viscous units use a special viscous goo in the limited slip portion of the diffs, that is kept seperate from the rest of the fluid. I have created a new post about this specific topic to get some input.

My factroy repair manuel calls for 80w-90 (GL-5) for both the r200 (open diff) and r200v (vlsd). I don't think the additive will harm anything, but I don't think it is necessary. I have had my r200v diff for about 2 years now with regular gear oil and it still works like a charm.

I am no expert on diffs, but naed240sx I think you have the right idea about a clutch type lsd needing a special fluid.
