Perhaps he was implying that and LSD and Active LSD are the same thing?

The standard lsd on R33 Gts-t's is in fact viscous and I spose could be called passive, as it responds to wheel slippage by fluid controlling the locking of both wheels.

An active lsd (Not too many Gts't's around with this option as it was around a $4000 add on option, correct me if i'm wrong) is actually the exact same (rear) diff you'll find int Vspec GTR's. Basically what this means is, there is a computer which (through abs sensors) actually measures if one wheel is slipping and uses hydraulic fluid to lock the diff.

The advantage of the viscous system is it's realatively cheap to manufacture and replace (many people just go with a kaaz 1.5 mechanical when they fail etc), the downside of a viscous type is that they will fail, and they basically just become less responsive over time as the bands inside the diff wear down.

The advantage of an active diff is that it's either open wheel (perfect for everyday driving, turning etc) or when you need it, locked. There's not really anything to wear out, as it's either open or closed, kinda like a mechanical locker you might see on a lot of old skool cars, but with a switch.

The downside? More things to go wrong I guess, computers, lines etc. And costly when they brake: Read: too much power, sticky tyres.

Hope this answered your question?

I'm not 100% sure on whether any non turbo skylines came out with an LSD mate, you're probably best off running a search or posting in the NA section of this site.

My initial reaction would be that they wouldn't come with an LSD though. Having said that, if you're looking at picking one up, there are plenty of viscous or mechanical ones going around that would fit.

(BTW, try not to hijack threads, you'll get more responses if you firstly: Search for your answer, if you don't find it: 2) post a new thread in the appropriate section).

Goodluck and welcome to the site.

I have one in my Gtst. With a PFC they fail intermittently (ie the Active lsd light next to the slip light near the tacko will light up-->mine seems to fail more often in hot weather). When they fail they go into open lock. If you stop the car and turn it back on the Active lsd light will go off (ie diff will be locked). Somebody told me that there was a fix for this where a wire is spliced and the problem is fixed.. although have not done a search. In the past (several months ago) i read all of the threads discussing this intermittent failure with the PFC installed and at that date there was no fix.

Its not really much of a problem like all the the other people who have them we just put up with the intermittent failure every now and again..The other day i took my car out for a thrash and it did not fail at all.

THe cool thing about this model R33 gtst that has this type of diff, is the slip light that lights up when the wheels are spinning excessively.. Coool for launching and when you hang round corners.

The bad thing about this diff is that it is expensive and extremely hard to fix as i think it was MOANIE (if i remmber from some of the forums correctly) found out when hers/his broke.

Fingers crossed mine isnt about to let go in that sort of way... it seems to feel pretty tight for now and its been through a bit in the past so i cant complain about its durability so far with about 200rwkw worth of power and 320 Nm of torque being delivered to the rear wheels through it.

      R34 Skyline climate control unit transistor

      By sinn3r · Posted

      I know why it happened and I’m embarrassed to say but I was testing the polarity of one of the led bulb to see which side was positive with a 12v battery and that’s when it decided to fry hoping I didn’t damage anything else

      R34 Skyline climate control unit transistor

      By MBS206 · Posted

      I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.

      R34 GTR Seats / No longer reclining

      Nah - but you won't find anything on dismantling the seats in any such thing anyway.

      Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
