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.

      Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
