J;s racing 1.5way plate diff.. anyone using one??

[b16a2]

any one using one or know of someone running one, they seem to be very cheap, so just wanting to see if to good to be true, if there are a few people running them with good things to say then mite look at them as an option, also any use them with high power like 300wkw, they standing up?/ (ps i expect to hear from you to mac, hell even some japanese examples would be good )

i think vtec_junky is running one in his DC, pm him and see what he has to say :thumbsup:

[doo0T!doo0T!]

I think they are made by KAAZ, I'm pretty sure it's the same design they have been building for years. They work the same as a cusco.

[Mac]

Vtec_junky is using one! Be good to hear his opinion. The recommended fluids from J's are Oberon which is not hard to get. I think we tried to nut out a local similar product. Now that we've got them sitting here we can also take measurements which was another hurdle but I am sure he'll chime in. And yes made by Kaaz, a very pleasant surprise!

[Gudgen]

so are they a KAAZ lsd built to J's specs or just a KAAZ lsd at a j's price??

[Mac]

It is the later =]

noisy at slow speeds is all i can say they lock up pretty good though

[Coupe-R]

wonder what they are like compared to ATS metal.

mine is like a locker at low speeds, banging around everywhere

That's what Robin's is like, lots of banging and crashing

Great pull thru the corners once you get going though

ATS owns all. i know quaife ones are very streetable and im wondering if the KAAZ units lean more toward that end of the spectrum rather than the all-out clunk clunk bang of the ATS/

qauife diffs are torsen type geared diffs, ats and kaaz cusco etc are all plate type, way diff... the torsen type diffs work on gears inside, and if preloaded correctly will not clunk etc, but they are no where near as good a clutch pack diff, they dont lock up as well, an both axels need to have a torque input into the diff, if on wheel spins up or is in the air, the diff will not bind up, so once it spinning, you have to wait till they both have traction and then go again...

the clutch pack lock no matter what... sure theres a trade off in drivability but if its a tarc car then who care about of abit of noise and clunking, you wont get a diff that lock up better than a clutch pack diff

few of the jap brand are actually the same LSD . . . .

[Coupe-R]

yeh my ATS is CRAZY CRAZY bad

I think its cause it was run in using honda MTF fluid, or somethings just up with it??

turning right locks up REALLY bad, turning left is just clicking.

I'm keen to go in someone elses ATS diff equipped B series honda

[Genkei]

for most of the aftermarket diff . .

if u run Honda MTF . . . it wont last Long . . . .

Best thing to run will e motul but if u r a budget Total or Elf will do the job

and if they are carbon material . . prepare to learn the 30min box out and in excerise . .

Having a 1.5way lsd is essential to drive around corners without losing control at high speeds

and yes very noisy at low speeds but it indicates that it doesnt have the right fluid in the diff thats why it makes the noise it needs the special oil to get lubricated. For Honda FWD you need to change the gearbox oil because the lsd is inside the transmission thats my 2cents

I run motul gear FF type 2
75/90

tried total oil and its utter shit, makes the syncro's grind worse on the track once up to temp. (and cold they grind bad) and the LSD is EXTRA clunky,
i think cause its a 80/90 oil and is like $40 for 4-5L

vs motul at $50L i think it is? or maybe its $50 for 2L?

I used this on my old Ek9 which had a cusco 1.5 way lsd, i bought 4 L for $140.00 Motul is awesome shit, feels much smoother.

I am running a ATS carbon diff and have for some time, no need to change out yet (touch wood).
Mine is super quite compared to others I have heard. I only get a little bit of chatter with very slow sharp U type turns.
Was awesome on the track really pulled me round corners

I am running total oil, synchos are just getting a bit chunking going into 5th and reverse but not that bad, might have something to do with the amount of torgue I am running though (as well)

[Genkei]

they are good, nice and quite and doesnt get the bang bang bang as much, just dont seem to last as long ... well the ones ive seen . . .

few cars in the local racing scene rebuild twic this season

elf has some nice oil too, slightly cheaper then motul

[Coupe-R]

That rebuild time would have HEAPS to do with the oils the trans is running.

Wrong oil wears them out like a bitch.

You are supposed to run ATS oil in them, but no one is N.Z brings it in.
If you know racers you may get motul wholesale for around $90 for 3L

[vtec_junky]

i do have the j's diff, and i really like it, its a bit clunky, but that was only during the bed-in period and once a changed the gearbox oil for new stuff its queitend down. its really good in corners and on the straight too
the closest spec stuff to oberon i found was this


and its working great

[Kelsonmassif]

whats the recommended oil for a Quaife lsd?
