Does The Stagea Have A Viscous Lsd?

[DaveB]

Hi all,

When I first started researching stageas a few years ago I was surprised to read that they apparently didn't have an LSD.

I came to this conclusion when I read that RS-Four S has "mechanical" LSD. As does 260RS.

But what is the standard LSD in say a 33gtst or 34gtt - viscous or mechanical? Is it possible that the standard S2 auto diff' is a viscous limited-slip unit?

Just about every S1 stagea diff' I have seen for sale said it was an LSD... that's something else that made me wonder about viscous LSD.

I am interested to know because somebody is selling a new viscous LSD R200 in the correct ratio for S2 auto and I would like to know if it would be an upgrade or not. I don't like the uncomfortable "sideways shuffle" of my stag atm (I'm sure if it *was* a viscous LSD it's worn and now running open).

Under what circumstances do you get "sideways shuffle"?

[QWK32]

I think a LSD was an option for the auto S2 stagea. I know mine definately isn't a LSD just make sure that if you change to a different diff center to use your diff gears, or use the crown and pinion wheel from the diff you buy, they are machined as a pair. I remember seeing somewhere that a S15 center will bolt in with your crown wheel, can't remeber if they were mech or viscous LSD though.

rsfours has a viscous and it was an option on all the other stageas . my mates auto has a lsd in it

[DaveB]

hmm interesting... viscous lsd... was that a series 1? I heard they wear out after 50,000K's or something, is that true?

[DaveB]

Under what circumstances do you get "sideways shuffle"?

Whenever there's a considerable lack of traction and over-application of power... lol but not trying to drift or anything... happens at very low speed (say 20km/h or less).

Doesn't happen as often with the wider rims as it did with the standard rims/tyres.

For example, going around a corner near my street, it's steeply uphill and off-camber. Turn in really slow and give it plenty of power and it sort-of "shuffles" sideways first at the rear, then the front, then the inside rear spins, then the outside, and it kinda crabs up the hill for a couple of secs then pulls straight. Kinda cool, and also kinda unpredictable. I think an lsd would make it more predictable, and feel safer around round-abouts lol. Still cool, just not LSD-style fun. But then with an AWD system like this it is probably safer to shuffle some of the excess torque to the front or the back and let it just spin away the rest.

Thanks that's interesting... I wondered about the whole diff' off an S15. I know the centres are exchangeable, so just to find the right ratio. Diff I found is actually complete in housing with the S2 6-bolt axle flanges.

Hi all,

post your VIN or chassis num and I'll run it through FAST and try and figure out if it was optional or not... so far from what I can tell it was *optional* and similar (if not the same) as most of the RB bearing cars Y33 C33 C34 R33 etc

All the optional ones are listed as "viscous" LSD so not sure about the "mechanical" ones.

[DaveB]

Optionals were viscous? ...hmm... not good. PM sent

There is 2 types of 6 bolt axles

Auto's are 3x2

RS4s and 260rs and GTR are 6x1. Larger diameter and stronger.

I currently have a RS4S complete rear end sitting here if you need something checked

at work one time (private property mods earth moving site.) there was alot of dust in our car park. and as i took the left turn i felt like i was in a RWD car again, went out sideways like crazy then snakied

as i counter steered while trying to get traction, was told by my workmates the front wheels where going just as fast as the rears.

LSD ? i dunno.

cause i used to own a single spiner RWD car, could only spin the wheel if you turned on that side. say left wheel was the spiner. turn left and wheel would spin, turn right, nothing.

[chef_stagea]

mine use to do that... put a new set of suspension in and was sweet as... sure your rears are shagged???

Thanks Darrin. Never knew there was a 6 x 1. Never been close enough to a GTR But I'm pretty sure this diff' is a 3 x 2... thought I'm not sure if $800 is a good price for it, although it is brand new. Here's a pic':

VLSD can be shimmed to make it tighter... How often have you serviced your Diffs?

Mine has an LSD, assumed to be Viscous, nice and predictable.

[DaveB]

Been serviced 2 or 3 times in 45,000K's so far. But I don't want to drift or anything... just getting used to the 4wd. Probably even a 1.5 is a bit over-the-top for my uses. A 1-way viscous would be nice; yes I read a how-to on here about how to shim your diff'.

1way, 1.5way... are you thinking of going mechanical?

[ステージア]

V-TCS (Viscious LSD Traction Control System) came standard in the Turbo RWDs including the Type-B

Viscious LSD came standard in the Four S also including the Type-B Four S

If you wanted an LSD in all the other models, it came in the S-Pack which was a combination of the Cold area pack & a LSD.

I got a S15 Helical LSD, bolt-in for S2 Autos only.

is that the whole diff, so the S15 diff gears are the same as auto stagea, does it matter if its a manual or auto S15 diff? or is it just the centre and use that stagea housing and gears?

[chook]

dont know about whole diff, i (the shop) just put the centre in. Pretty sure the auto S15s came out with viscous, not helical lsd, JDM that is, not sure about here. From memory it was only the S2 auto, not S1 nor S2 manual, that had the same output shaft spine specs. R34 GTR also uses helical LSD, not sure about its compatability though. One thing about these diffs, they dont use an LSD oil.
