My apologies.

To clarify: I don't want to move away from the active rear differential, however if people know of an aftermarket replacement for this, that retains the electronic control is be keen to investigate it.

:)

AFAIK there is no aftermarket upgrade to the A-LSD.

Let's be brutally clear here. The very best active diff in a car of similar technological vintage to your GTR is the one in the EVO. Like the EVO 9 for example. Serious users of that car will pay quite large sums of money to buy the mechanical diff out of the RS in order to get rid of the pox-ridden active diff. They usually have to do this because the AYC diff just shits itself, but right up uuntil that point they're usually complaining about how they hate what the diff is doing.

Thanks for the input guys.

I won't have the funds to be able to change the rear at this stage but will give it a look in the future.

I've got some expensive panel work to take care of!

Thinking next year I'll refresh the bushes, suspension links and sway bars then see where to next.

Hmmmmm, so will the quaife be any improvement over factory if I'm not changing the rear?

It will, but it will make the A-LSD in the rear behave in VERY strange ways.

I did my front first and rear later. The rear would not lock up properly anymore. It must have something to do with the g-sensors or something that is governing the A-LSD system...

Either way, more grip at the front = the rear A-LSD very unhappy.

Wow, this is quite a disappointment.

Guess I'll keep the diff in storage indefinitely as I'm not wanting to move away from the active rear diff any time soon, otherwise what's the difference between a v-spec and standard after the suspension has been replaced.

Thanks for the input.

The badge, front and rear diffusers on The V - Spec, 2 extra fields on the MFD and the quicker 4WD computer.

Nissan should have done us all a huge favour and left the mechanical diffs in instead of being fancy.

In other news, doing the engine Mounts realigned the intercooler to intake manifold piping, fixing a boost leak I didn't know I had.

Found a second hand front pipe and got rips to make a pair of AFM Delete pipes.

FPR and retune later and I'm up 25kw with a similar gain in torque.

  • 2 weeks later...

what about changing diff ratios 4.11, utilizing the gtr 33 v spec diffs?

would make the car feel more responsive but you'll be shifting alot more often but it would be more fun on track days.

I've also Binned my A-LSD aswell...

I just put a cusco one-way in the front of my R34 V-Spec (<$1k landed). A-LSD hasn't caused any issues as yet, but I've not pushed it hard or been on the track yet.

The A-LSD thing is annoying. If it was as easy as replacing the centre, I would have done it already given everyone's feedback on diffs.

I'm doing similar things to the OP:

Got Bilstein PSS9s, Ikeya upper arms F+R, DBA4000s, crap pads (going to change) and have ordered the Whiteline sway kit F+R+links.

Having said all that, you can't discount the impact of good tyres. I'm running on 400 treadwear P-Zero All Seasons which are not confidence inspiring at all. Would budget for good tyres.

Feedback on rigid collars is interesting.

    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
    • There is a warning that "this thread is super old" but they ignore that anyway...
    • With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
