lsd? 2way? 1.5? Input please.

[No 240.. No id]

Hey everyone, am trying to buy a diff that locks pretty good and doesn't make any noise.

Am not trying to drift the car(too much money and time to do that), i just want something that locks pretty good.

Am thinking about the nismo 2way, But i did some searching and found out that it makes a lot of clunking noise and i don't want that at all.

I want something quiet and won't hear anything.

The car is 180sx, it comes with a vlsd, but if feels really bad, I had tested it with a burn out and two tires mark(easiest way to test it), but when it comes to a turn, it feels like crap ( and it feels like an open diff).

Its not a open diff, because it has orange sticker and label as vlsd.

The most important thing i want is that it doesn't make any clunking noises, This car is not my daily, Also its not a drift car. Just a car that am trying to keep clean and quiet as the same time.

Positive input please. Thanks for reading.

Search and pick your poison, there's plenty of info out there and reviews for you to come up with your own conclusion...and oh yea you got the wrong car for what you want. cheers

[EvilRB]

Nismo is going to be the quietest diff out there, if I were you I would just shim your VLSD for the cheapest and best way to go.

Search for the DIY how...

[ultimateirving]

So in your research have you found out what causes the clunking?
most LSD will be noisy, especially compared to the stock vlsd. Even my shimmed vlsd does some clunking in tight turns and reverse..

If your not drifting, and the vlsd works when going straight.
Then why the desire to change?

[EvilRB]

AND I'M TELLING YOU THAT IF YOU THINK THAT NISMO 2 WAY IS NOISEY THEN YOUR NOT GOING TO LIKE THE FUCKING REST! THEY ARE LOUDER!

Nismo is one of the quieter diffs out there because of the fact you can run synthetic oil with them other diffs you can't

Trust me I know I have heard them all and I run a Nismo 2 way now and I know first hand it is quiet.

Here is my thread on it: http://zilvia.net/f/tech-talk/512229-used-nismo-2-way-lsd-maintance.html

[BoredEE]

Look into OS Giken, I've read that it could be "tuned" to not be so aggressive.

I have no experience with that product, just hearsay I've read on the internet.


Also why not go with the S15 HLSD? its maintenance free and not as aggressive as clutch LSD's.

[jr_ss]

If you want an LSD that locks and doesn't make any noise you should be looking at the factory S15 helical. All other types besides the VLSD are going to make noise. If you're not drifting, that's your best bet.

I never heard a Nismo diff before, but i searched around and people are saying that you will hear noise from any 2way lsd.

All i want is something that doesn't make noises and have a good lock.

There is a guy local selling a Nismo 2way lsd, but i don't know how it will sounds.

[jr_ss]

You're not going to get what you want. I'm sorry but any mechanical diff besides the helical is not going to be quiet.

This is all i want to know. Thank you sir.

my nismo 2 way lsd running redline fluid is loud as hell. Its has gotten louder lately, time for an oil change. I got it used with less than 5k miles on it, assembled in a s14 pumpkin already, and Im planning on checking the backlash on my next oil change. But it is definitely loud, at really low speeds and tight turns sounds like bad sub bushings, tires locking and unlocking chirping and shit, but when u get on it it grabs like a mofo as well as when decelerating/coasting. Also keep in mind it will make your rear-end much louder, especially if u have polys or solid subframe bushing and when decelerating.
By what i've researched it is normal for nismo lsd's to be loud, clunk and make ugly noises, even though nismo claims to sell one of the most civilized lsd...

OS giken is silent, but helical is 1/3 the cost.

[brndck]

If you want quiet, carbonetics with carbon plates is pretty quiet. Helical is the way to go tho. S15 helical sounds like what you want. All clutch type diffs WILL make noise.

[guitaraholic]

I have an S15 diff in mine, and honestly, I could not tell hear it one bit, in fact, it got quieter after installing the new diff. It drives just like stock till you take turns or accelerate really hard, then it let's you know you have it back there. Back end really wants to come out on turns when the power comes on.

This.


Also 2 way vs 1.5 way doesnt really have any impact on the noise besides what driving maneuvers will lock it up

[AJZax]

I'd say shimmed VLSD or helical S15 diff. I think everyone is steering you in the right direction.

I shimmed my VLSD, ran a season of grass roots, daily drove to school and work everyday and no problems. Feels like a welded (replaced factory shims with new ones and put 1 extra in [.8mm thickness I think?], it feels like what people describe as with 2, the diff was not worn out when I shimmed it either haha). It still locks. For a cheap simple solution I suggest shimming.

So if you're not drifting, just get helical or shim. No point in spending $1k on a diff you're not even going to like lol. Even if you are drifting, just carefully weld the diff right and you'll have better reliability and it'll be gobbs cheaper.

For a daily "luxury-build" I want to start soon I'm just going to run a mildly shimmed VLSD. Factory condition VLSD will be great for a mild track car and comfortable street car without any annoying tenancies.

[SilviaSR20DET]

I say go nismo 2way, it is really quiet for daily use thats if you use the right fluids. I suggest getting the motul diff fluid for the nismo as this has made my diff significantly quieter. Locks great too!

[MrChow]

This thread...
To the OP. The quietest LSD will be pretty much your VLSD or S15 Helical. Have you tried changing the oil? Remeber VLSD is viscous works off of the oil so if that oil hasn't every been changed it won't work.

To the 1.5 or 2 way from what your asking I would say 1.5 way. There is less chunking but again your going with a race part for the street nothing is going to be prefect. You will hear noises from any mechanical. Even in STI and Evo they'll make noises... Your asking both wheel/tires to spin at the same time while it's taking a turning...

To the LSD brands Nismo has more just Nismo, there GT, R-tune, S-Tune etc etc. So there are quite Nismo out there and there are loud ones. Do your research on them before hand. There is Plenty of threads on here and the web about which one is quieter.

IMO on the quietest ones that'd I go with would be:
Carbonetics
ATS
OS Giken

[jr_ss]

The VLSD is a sealed unit, so changing the oil isn't going to help it lock any better.

[MrChow]

Um... I'm just asking if the oil has been ever changed because I'm more than sure that if it hasn't it'll work a lot better than it did before. That's what I remember when I had a VLSD didn't work that well at first had it, then I changed the oil and then it actually worked more than half the time....

No offense, but you're saying if he changes the oil his VLSD will work better. I'm saying that is not the case and will not happen. It's a viscous liquid, which gets thicker as it heats up, much like your clutch fan. Over time and with beatings this liquid breaks down. Changing the lubricating oil is not changing the viscous fluid, therefore an oil change will have no effect.

The quietest LSD will be pretty much your VLSD or S15 Helical. Have you tried changing the oil? Remeber VLSD is viscous works off of the oil so if that oil hasn't every been changed it won't work.

silly rabbit, everyone knows vlsd's work with sealed packages of expandable gel that once worn out just cant recover!

[towlie]

The s15 hlsd will properly support your needs

[Croustibat]

Hey everyone, am trying to buy a diff that locks pretty good and doesn't make any noise.
[...]

That does not exist, you can stop searching now.

Locks good = clutch type LSD. clutch type = noise & high maintenance.

VLSD are quite crap, but silent.

Torsens are not really locking, but do a silent job and split the torque very nicely.


the only way that would be silent & lock is ... welding the diff. But it sucks.

[Croustibat]

If you want an LSD that locks and doesn't make any noise you should be looking at the factory S15 helical.

Except it does not lock. I know, i have one. Get one wheel in the air and you get all the torque on it.

[Croustibat]

Thanks for pointing out the obvious. I have two, what's your point? Most people here don't use the car in ways you or I will...

[Croustibat]

My point is in the OPs very first requirement : " am trying to buy a diff that locks pretty good" . A torsen does not lock, so the S15 helical is out. It is not a question of using it or not. That is its first requirement.

[jr_ss]

Dude- you really like arguing semantics

The fact is a Torsen does lock when both wheels have traction. It acts as an open with one wheel in the air or on surfaces that don't provide enough break away torque to lock it.

[Chris28]

I have a Tomei Technical Trax 2 way and it's silent. I put a bottle of friction modifier in it when I filled it. It locks fine at the track but pulling into my driveway I still get some inside wheel spin.

[moco]

Get an open diff weld it. Locks all the time with no noise


Problem solved :)

[RB25GUY]

yea stay away from ats metal deftforce lsd's if u dont want noise although i read that there carbon plate lsd are quiet pretty easy to rebuild and deliver 20kg of torque instantly and cost about2 grand ):

[No 240.. No id]

Thank you everyone, I think s15 helical diff is the best option for me.
