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).

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.

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,

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

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.

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.

Thanks Darrin. Never knew there was a 6 x 1. Never been close enough to a GTR :D 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':

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?

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.

(This information for series 2 only)

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?

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.

    • Yeah, all the crude is used for fuels and petrochem feedstocks (pesticides, many other chemicals, etc etc). But increasingly over the last few decades, much of the petrochem synthessis has started with methane because NG has been cheaper than oil, cleaner and easier and more consistent to work with, etc etc etc. So it's really had to say what the fraction either way is. Suffice to say - the direct fuels fraction is not insigificant. Heavy transport uses excruciatingly large amounts. Diesel is wasted in jet heaters in North American garages and workshops, thrown down drill holes in quarries, pissed all over the wall to provide electricity to certain outback communities, etc etc. Obviously road transport, and our pet project, recreational consumption camouflaged as road transport, is a smaller fraction of the total liquid HC consumption again. If you're talking aboust Aussie cars' contribution to the absolute total CO2 production of the country, then of course our share of the cubic mile of coal that is used for power generation, metallurgy, etc adds up to a big chunk. Then there is the consumption of timber. Did you know that the production of silicon metal, for example, is done in Australia by using hardwood? And f**king lots and lots and lots of hardwood at that. Until recently, it was f**king jarrah! There are many such sneaky contributors to CO2 production in industry and farming. NG is used in massive quantities in Australia, for power gen, for running huge water pumps (like, 1-2MW sized caterpillar V16 engines running flat out pumping water) for places like mine sites and minerals/metals refineries. And there are just a huge number of those sort of things going on quietly in the background. So NG use is a big fraction of total CO2 production here. I mean, shit, I personally design burners that are used in furnaces here in Oz that use multiple MW of gas all day every day. The largest such that I've done (not here in Oz) was rated to 150MW. One. Single. Gas burner. In a cement clinker kiln. There are thousands of such things out there in the world. There are double digits of them just here in Oz. (OK< just barely double digits now that a lot of them have shut - and they are all <100MW). But it's all the same to me. People in the car world (like this forum's users) would like to think that you only have to create an industrial capability to replace the fuel that they will be using in 10 years time, and imagine that everyone else will be driving EVs. And while the latter part of that is largely true, the liquid HC fuel industry as a whole is so much more massive than the bit used for cars, that there will be no commercial pressure to produce "renewable" "synthetic" fuels just for cars, when 100x that much would still be being burnt straight from the well. You have to replace it all, or you're not doing what is required. And then you get back to my massive numbers. People don't handle massive numbers at all well. Once you get past about 7 or 8 zeros, it becomes meaningless for most people.
    • @GTSBoy out of the cubic mile of crude oil we burn each year, I wonder how much of that is actually used for providing petrol and diesel.   From memory the figure for cars in Australia, is that they only add up to about 2 to 3% of our CO2 production. Which means something else here is burning a shit tonne of stuff to make CO2, and we're not really straight up burning oil everywhere, so our CO2 production is coming from elsewhere too.   Also we should totally just run thermal energy from deep in the ground. That way we can start to cool the inside of the planet and reverse global warming (PS, this last paragraph is a total piss take)
    • As somebody who works in the energy sector and lives in a subzero climate, i'm convinced EV's will never be the bulk of our transport.  EV battery and vehicle companies over here have been going bankrupt on a weekly basis the last year. 
    • With all the rust on those R32s, how can it even support all the extra weight requirements. Probably end up handling as well as a 1990s Ford Falcon Taxi.
    • Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.
