No. Firstly the gear ratio is different. You may be able to take the ratios from your 33 diff to fit into the 34 diff.

But there are other complexities with replacing a 33 vspec diff, I'm not sure of the details maybe try a search around. 33 vspec have some whiz bang active diff with lots of bits that make it work....

It's a bloody shame no one has come up with a solution for putting an LSD centre into the A-LSD housing. Surely with Nissans level of interchangeability between models there's something that fits. Someone like Award could possibly come up with a solution. Otherwise there's going to be a shit load of A-LSD's laying around rotting once they've all been swapped out!

Thanks Team, Yep it would shag the ratio in the 5 speed. Forgot about that.

 

I'll just have to go the route of replacing the shafts and putting a non-vspec with a 1.5 in.

Cheers.

I have a 3.54 front diff if you want to try swapping the rears.

Nice one!!

I must be the only person considering putting an A-LSD into a Skyline. Street car GT four though, I'm currently suffering with a viscous lsd...

Seriously though, they are just a clutch pack LSD, actuated via computer controlled hydraulic pressure. I'm wondering what it is that causes them to go bad. I have read that they don't like too much heat, and over 350kw they would appear problematic, but I'm unlikely to test that limit.

One interesting thing i read, they lock more with increasing lateral g, which seems sensible. However- if you have installed an ATTESA controller, typically these reduce the lateral signal, to get more front drive, but as you can see this would reduce lsd lock at the same time. I'm fascinated by the computer control, so hopefully I'll try it one day! On the lookout for cheap R34 v-spec attesa pro ecu's :)

You make it sound so simple! But a mechanical LSD is even more simple.

If one had a car with the A-LSD it would certainly be worth trying to give it a good service before giving up on it. There is a piece on how to do that at the top of this section...but it seems a little OTT to install one (instead of a mechanical LSD) when there is not one there!

Installing a mech lsd was certainly my first plan, and yes understand it is a lot simpler. But then i read a few posts recently about them being a pain around town, needing to clutch-in around tight corners etc. perhaps i just need to find a loose one.

Never mind what a few posters say. GTRs come standard with a mechanical LSD and I put one in my Stagea and there was no "putting the clutch in to turn tight corners" nonsense nor was it at all harsh. Some brand new aftermarket LSDs need a little running in but that would be nothing compared to the headache of trying to install a V-spec LSD. oops advice a year late I see:blink:

I have a V Spec R33 and right now I'm trying to sort an Attesa problem and which also is only letting the left rear tire get traction

If you are spinning the rear right tyre too much then it sounds like your A-LSD isnt locking up properly, so try bleeding it on top of the diff for a start. If it’s always biased to one wheel, maybe check if one of the brakes is dragging too. Got any warning lights on the dash?

When i got my GT Four I bled the attessa fluid and it was thick like old engine oil, yuck. Replaced with Transmax Z.

    • 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.
    • 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.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
    • Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
