Source for Quaife HLSDs? And Q about S15 diff. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

trackstar · 06-07-2005, 08:04 PM

I will be in need of an LSD for my soon to be acquired open-diff S13, and in researching this site as well as others I have come to the conclusion that I need a helical LSD (road-racing/HPDEs).

If I opt to go for a Quaife, can anyone recommend a reputable vendor to purchase from? I have browsed a few Quaife dealers' webistes and they all list the unit at full list price ($1495.00!! Ouch!!).

I guess my other option is an S15 diff. Are there any differences between S15 diffs, or are they all the same? Is there anything else needed for install into an S13 other than the LSD unit and the 2 S15 output shafts? Also, does the S15 diff change the final drive ratio?

Thanks.

You want an S15 Spec-R differential, which came on the turbo, 6-spd models as well as the special Autech N/A 6-spd version.

Search for other S15 diff threads, I know Turdz posted pictures before. U should be able to look into the internals and see the helical cut gears.

Just take the internals, swap them into the open differential pumpkin, and bolt the whole thing back in, and viola, you got urself a badass diff for grip.

Combo with Falken Azenis Sports and you are on your way to pwnage.

But search for sure for s15 differential, there has been much discussion in recent months.

Quaife is very very expensive, unless you are hardcore racing it is probably not worth it. Some people also like the 1.5Way clutch type diffs for road racing, and they are probably also cheaper than Quaife.

chmercer · 06-07-2005, 09:50 PM

heilical diffs never wear out, and require no maintenance, because they dont work. save your money.

OptionZero · 06-07-2005, 10:18 PM

wha...? wtf are you talkin about?

chmercer · 06-07-2005, 11:33 PM

they suck ass?

OptionZero · 06-07-2005, 11:52 PM

oh yeah, of course. Yeah they suck, don't get one.

chmercer said so.

Don't get OEM aero either, they suck.

Don't forget to buy his stuff.

ZK · 06-08-2005, 12:08 AM

Yeah, HLSD suck .. for DRIFTING. When you want to maintain traction through a corner, you don't need/want full lock. If you want fast lap times, then it is plenty good.

There are better clutch type aftermarket units but for the $$ and the fact that they last, it can't be beat.

trackstar · 06-08-2005, 01:43 AM

I PM'd turdz for a pic so I can be sure I am looking at a genuine S15 helical diff. Can anyone confirm by the pics in this link?

Click me

Any ideas on who sells the Quaife?

I just got s15 everything. I got the diff aswell, and for the price I see its worth, what will you pay for one with the whole diff, axles, and a fresh 19k on all?

OptionZero · 06-08-2005, 09:09 AM

i know. People only get OEM aero cuz they wnna be JDM tyte. No sense of style at all man.

I say if the kit doesn't scrap the ground, it's just not worth it.

who needs durability and fitment, much less personal preference.

wrong. 1.5 way 70% locking powe will own it any day. for traction. and clutch type isnt much more than u pay for a stupid helical.

dont forget u have to get output shafts. what? huh? you can find them cheap? fast? yea, i didnt think so. count overhead costs.

Geez, take time to even finish reading my post! I said there are better clutch type aftermarket diffs that are better but they wear out and overall costs more $$.

Which you rather have? a $700 LSD that lasts the life of the car or a $1000 LSD that you have to rebuild every year or two? Personally I want to put something in and not have to worry about it. reliability counts.

OptionZero · 06-08-2005, 12:40 PM

Has it been definitively shown that a 1.5way clutch type is better than a helical? There was a big debate on FA a while ago, but didn't ever come to a conclusion

Plenty of quality cars have helicals: the Miata from' 94 up I believe, the STi, EVO, and SRT-4 all have helicals in front (and clutches in back), all Type-R's have helicals, the RX-7 and RX-8 i believe also have helicals

BoroBoroS13 · 06-08-2005, 12:45 PM

I was going to get a HLSD the other day but my supplier was out of stock. I can get the whole diff and axles for about $400.

But yea, your going to need the output shafts and the diff itself. I wouldnt pay anything over $500 for everything though. If its gonna cost you more, save up a little extra cash and get a 1.5way. Also, if your into drifting at all dont get a HLSD.

*HaLo* · 06-08-2005, 12:47 PM

BoroBoroS13, where do you get them from? Nissan? I'd be interested in getting one from you if it's new and it includes the shafts..

Please share. This diff would be ideal for my needs and that sort of price would be great.

A Spec Products · 06-08-2005, 01:35 PM

Shameless plug, but we're a Quaife dealer (who won't sell at full pop).

Shoot me a PM with questions etc.

BoroBoroS13 · 06-08-2005, 03:16 PM

My hook up deals in used parts from Japan but right now they are out of stock and I need to check back with them to see if/when they will get more. I will let you guys know once I get more information from them and recive a diff for myself.

ryan hagen · 06-08-2005, 05:36 PM

another issue, if you do get one and have to order outputs like me, rare trick and i guess j-spec too will send you a pair of left side outputs, then you are like me, stuck with a h-lsd with 2 long side out puts so no go, i ve waited like 6 months+ for raretrick to send me a new short side out put but i doubt i will ever see it.

OptionZero · 06-08-2005, 08:03 PM

there's a guy on ebay that has 'em every month. Just under $700 shipped I believe, very reliable.

If you have any intention of going on road racing, auto X, or canyon carving, the HLSD is terrific

withy · 06-09-2005, 12:09 AM

this was posted on nico a month or 2 back

"The S15 helical (which comes from the spec-R car in japan) will go right into the R200 on an S13, or S14.
The diff has nothing to do with the drive ratio !!
The final drive gears consist of the pinion, and the ring gear.
There is no need to remove the pinion gear when changing the diff,
and the ring gear bolts to the diff.
So what ever gear ratio you have now, is the ratio you have after installing an S15 helical.
The only problem people get into is that if they buy an S15 helical without the output shafts.
They are larger than the standard R200 shafts.

I have one S15 helical in stock, and several in transit from Japan.
The one I have now does not have the shafts,
but I also have new shafts from a dealer in transit.

There is a shop in Walnut CA (J-spec USA) that is advertising new shafts, and I ordered in 2 sets, but it was a scam !!!

The S15, like most other Nissan diffs takes 2 different length shafts (side 'A', and side 'B').
When the shipment came in today, all that came was the side 'A'.
This Rip-Off joint will not return my calls or e-mails - so beware!!

So now I will have to order 4 more side 'B' shafts from Japan.

For the complete set (S15 helical & both shafts) I get $650.
And I will sell the new shafts (pair - left & right) for $350.

I expect these shafts to be hitting my door in about 6 weeks.

haha, stupid helical. whatever.

the s15 diff + output shafts aren't as expensive as you think shipped from a japan, just gotta look in the right place.

OptionZero · 06-09-2005, 01:32 AM

yup, i got mine from Gordon the Duax guy. Terrific seller- u want a diff, he's ur man. He's got miata and Rx-7 diffs up the wazoo too.

trackstar · 06-09-2005, 06:06 AM

Cool, the duax place is the ebay link I posted up earlier in the thread...glad to hear he's reputable.

hurleyboi514 · 06-09-2005, 07:29 AM

Helical is the shizzle... i remember i autox'd the weekend after i got my diff in, and it was a night and day difference. when i used to put on the power mid corner at any point, i would get wheel spin and no accelleration. afterwords, i could keep my foot planted post-apex all the way till the next braking point! i love it!!

Not nessecerily a Scam but OK...
Personally I was screwed into the same situation because of a Nissan Dealership that obviously doesn't know what they are selling... and it just so happens I turned the product over to the customer and now I have no real way to fix the problem. (as you can see from Ryan Hagen post).
My best option in this situation is to offer different Flanges off a Nismo GT LSD.

Several Companies are offering Left and Right Sides... but selling 2 Right Sides... Its not a Scam its ^$&% ignorant Nissan Dealers.
