TIRED OF THE S15 helical LSD mystery?

[splitsecondperformance]

I bet everyone out there interested in the S15 silvia helical lsd, has got a few questions to be answered. Well here goes, first of all I am tired of people trying to sell there helical diff knowing good and well that a US Nissan Dealer can not and will not order the output shafts. No other output shaft will fit, except for the S15 helical lsd output shafts. If someone tells you that S14 output shafts will fit he lied to you. I personally went to the trouble of trying to order the output shafts, and all I came up with was no, sorry, try ebay.
Well I went to the trouble, of going to a local nissan only parts yard. I spent the better part of a day pulling input shafts from every model of nissan that was rear wheel drive, and all I came up with is this. All nissan open diffs from 89 to 98 used 30mm X 29 spline shafts. VlSD won't work because the locking ring is in the wrong spot, and again a 30mm X 29 spline shaft. J30 is the same as Z32 and they wont work either, plus they have 5 bolt output shafts, unlike the silvia that has the three groups of two. The only thing that I can tell everyone, is to find a importer that can get the diff or just the outputs. By the way, the S15 lsd will bolt right into your S13 open differential, S14 open diff, and VLSD differential housings of the R200 family. Open or LSD it will go. I am currently working on trying to find a supplier for the s15 rear diffs, who is reasonable in price and shipping. Stay tuned for the conclusion, :gives: when Jake installs a helical S15 lsd into an S13 open diff............................

not really, its been known for a long time that JDM only shafts are needed.
of course ppl are going to make things up to make them selves feel better/try to sell somthing. you just need a little common sense to sort thru the bullshit.
sounds like you had a bad experience... but dont worry, most of us have had similar experiences. thanks for verifying that all those shafts dont work. :D
perhaps the r32 gts-t shafts work, or some other GTR shafts?
btw-- did you try courtesy? you may be able t oget them to order somthing from japan.

You know, you didn't have to go through all that trouble if you did what ? .. what ? .. what ???... I cant hear ... SEARCHED !#[email protected][email protected][email protected]


good luck with the install .. muahaha .. i know something you dont .. MUHAHAA
:)

[DuffMan]

Some people were saying that some open s14 shafts would fit. I never really understood that though, since all open S14 shafts had the same part #.

Nice work, splitsecondperformance, good luck sourcing the JDM shafts.

Tried Courtesy Nissan, the guy I talked to told me he didnt have a way to get parts from japan. :bash:

[hurleyboi514]

i ordered mine from jspec.com

[sykikchimp]

The s15 diff half shafts don't use a locking ring. The 30 spline s14 vlsd shafts ( I think 96+) are the only shafts that MIGHT work. don't worry about the locking ring. If you can get the shafts in the diff, then they aren't comming out.

and you can get different axles with the 5-bolt flange if you found 5-bolt shafts that fit.

[old_s13]

why would anyone go through all this trouble for just an LSD?

My advise is become a ebay master! Just look at what I picked up last week with the handy dandy buy it now button.

[nismo2491]

courtesy can and will order parts from japan. I wanted something from them a while back that was a japan only part. the guy said he could order it, it'd take almost 2 months to get, and it wouldn't be 100% on the price until he got it. he said he could tell me it'd be roughly this price but not for sure. ask for bruce next time you call.
i think it may have been JDM kouki s13 front.

[hurleyboi514]

holy shit, nice diff... only $16 to ship, so your paying like $66 more than i did, but you got the output shafts. i ordered shafts last week, ill end up having about $500 in the whole set up...

[mellojoe]

Does the s15 helical diff use the 5-bolt output pattern like the 300zx? I know the same output shafts won't work.

But, you can use the j30 axles (on an s14, maybe s13) to bolt up a 300zx diff with its stock output shafts. I wonder if the same will work with the s15 diff?

[AKADriver]

What's the trouble? You find the parts you need, buy, install. The S15 HLSD is a cheap, damn good LSD for the "grip" driver.

If you buy an S15 HLSD carrier and side shafts, that's the only "special" stuff you need.

[sykikchimp]

the s15 shafts are 6-bolt 30 spline and I think 31mm.

ILivetoDrift, could you please measure the diameter of the shafts when you get them so we can compare to other cars to see if there is a USDM alternative?

[Jeff240sx]

What are Z32 NA lsd shafts? They haven't been brought up and I know they're different than 240sx shafts.

[Muzzy]

got damn it ilivetodrift!!!
i know that guy...man i gotta check his auctions more often. he live pretty close to me

[Ghettokracker71]

whats the gear ratio on an S15 HLSD?

[hurleyboi514]

3.636 i think... same as stock 240 open diff...

[LanceS13]

stock 240 open dif is 4.08

[okashira]

and the helical is whatever you drop it into. ratio is determined by the Ring and pinion

[hurleyboi514]

oops, my bad...

[Ghettokracker71]

awsome....sounds like an S15 HLSD is the ticket for me....:):):)

The top of the shaft (cones in) is 24mm while the part with the teeth is 29-30mm. I didnt know which part you wan me to measure. it really has 3 differnt diameters on the shaft.

[sykikchimp]

I am almost positive 96+ s14 LSD shafts would work then..

[DuffMan]

You know, I wouldnt be entirely comfortable with a input shaft thats a mm too small. Though it may work and the metal that the ouput flanges is very strong, its less surface area, and those splines arent exactly deep to begin with.

You might be able to just order S15 flanges from a dealership if you give them part numbers 38220-4P060 and 38220-4P061. If you put those numbers in a google search, you see that they were part of a Nismo lsd kit, and SUPPOSEDLY Nissan dealers are supposed to have access to the entire Nismo parts catalog.

Anyone want to call their dealership and find out?

[slideways240]

if steve richardson is still at courtesy he will order them, he bent over backwards getting me a nismo rear STB(like 5 years ago)

[sykikchimp]

where did anyone say they were a mm smaller? If the s15 shafts are 30 spline, 30mm, and the S14 obdII cars are the same as I suspect they are, they should work fine.

[DuffMan]

I'm not really 100% sure, since I dont have one. But if you put this link http://www10.plala.or.jp/s15/3d_def.htm in babblefish it comes out like this:

"And so on being to be, side flange specification super being to become difficult, it does. By the way as for the side flange of S15 φ 31mm, before the S14 previous term φ 30mm. Thicker one does not enter physically in those of time before the S14 previous term, but when it is opposite, being to enter normally note is necessary."

So i dunno, but the jist of that poorly translated blurb I think is that S15 is 31mm and the S14 is 30mm, and they are exchangeable one way but not the other.

[sykikchimp]

He just measured them with a caliper to be 30mm..

It says S14 "Previous term" which I believe could mean "95-96" models. I have read before that the output shafts are different on the later model "Kouki" s14's.

um, are those the JDM part #'s, or the Nissan Motorsports part #'s? i ordered mine through Jspec.com and used part #'s Right flange-38220-29U00 Left flange -38220-29U01. thats what i found from a couple other posts from guys that had to get flanges from Japan...

[DuffMan]

They are JDM part numbers but all Nissan part numbers follow the same format. I was thinking maybe a Nissan dealer could get them, because they come with a certain model Nismo LSD, and supposedly Nissan dealers had access to the whole Nismo parts database. There is an old thread on FreshAlloy where people where comparing output shafts and a guy posted a picture of the output shafts he got with a Nismo LSD with the boxes, and they were that part number.

Not sure if he got that Nismo LSD from a Nissan dealer or what.

Sykikchimp I cant really comment on the 30mm vs. 31mm thing since I dont have any S15 output shafts to measure, so maybe the kouki LSD output shafts are an exact fit. I'm not even going with a S15 LSD anymore, I bought a R32 GTR diff and when that gets here I'll post what fits in that, if anything. :x:.

[slideways240]

someone buy me some gear oil and i'll measure mine :D
