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.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
