Darren...

how could you want to sell the Nismo GT Pro?  :D

Especially since you bought it from me freshly run in! haha.. It's such an awesome diff, you'll miss it when it's gone......

One my GT Pro in my S15, I found that setting the initial torque to medium made it nicer to drive.  Sure it still clunks, but with regular oil changes (castrol diff oil, 75w140 i think) and the medium setting, it's a lot more tolerable.  At lower speeds, just need to either work the clutch, or slide the tyres around ;)

take care!

Lol, howdy mate. Dont worry i havent sold it. I actually went for a drive yesterday and asked myself what i was thinking :P

I havent played with the settings yet (still as is from when i bought it off you :P ) But i would like to try to go to the medium setting to see what its like. I just havent had the time to get under there yet and pop the half shaft out :)

I'll give the medium setting a go soon ;)

With regards to the s15's diff (or the gtr's) being weak, i still find it hard to believe.

Yes i have heard of the s15 gearboxes as sheit, but never heard of any diff problems. id say they have one of the toughest factory diff setups.

Unlike Holden who only warranty the damn thing for 12 months :P

'Weak' is a term that someone else used.....it's all relative. Having had one apart and seen the design I can see where the potential for failure is greater given particular features of the Torsen T2 design (S15/R34 base).

I do agree... Looking at the design you can see the how it would be weaker. :)

I'm aiming for upwards of 300rwkw.

The current VLSD does what it whants when it wants, it seems to really like to let go of the left wheel during second gear acceleration.

I might give Tilbrooks a buzz as they have built worked with R34 GTR's and quite a few s15's and see what they think on the helical s15/gtr diff's.

Don't do it Darren!!

Joel could probably tell you, my diff, ATS 1.5way is pretty quiet, it doesn't clunck all that much, only in shopping centre type turns

I'd have a go adjusting it mate, once you get some big power, you will need all the grip you can get. Maybe try the medium and hard setting, in theory, the more pre-load, the more it will just squeal a tyre, and not dis-engage the diff.....

I think Nightcrawler lunched his diff in his S15 a while back didn't he? I remember a problem he had with open wheeling or something after a few drag runs

ok.. I've made my decision..

GTR Diff... I've found a second hand one from the wrecker for a pretty decent price.

If it won't fit up with my axles i'll grab the GTR axles and hubs.

With regards to setting the diff tighter causing it not dissengage.. Sounds like a good idea. The clunk and wobble when it disengages is the horrible part of a mechanical clutch.

give us some more details on this! what type of LSD does it have and which GTR you getting it out of?

Clint32 has a GTR diff in his 32

had to use GTR hubs and driveshafts as far as I know

I think his was out of a R32

Good choice in keeping the 2way Darren!

My diff needs a oil change, what have you been using in yours?

The GTR flange is the same 5bolt flange as the GTST's. Well so I've been told by an importer.

For the GTR center to fit up in your GTST diff housing you will need the GTR center and half shafts.

IF you want the tougher GTR axles grab the GTR axles and hubs.

I'm going to drop the whole GTST housing grab the GTR center and half shafts and track down a S15/S14/S13 Auto 3.9:1 crown and pinion then take it to some one to install and shim up to make sure its nice and tight.

Hopefully the 3.9:1 will help fuel economy a little and make use of first gear. 40km/h in first at peak power isn't much fun. :D

Been using the Redline oil. Cant remember what spec. Bought it at Mile end AutoBarn. Im going to do an oil change when i up the preload.

Im also swapping the crown wheel and pinion over to the 3.9 same as Cubes, so i can get a little more out of first.

I've seen them. :rolleyes:

I would think not benifitial for street, but most definitely benifitial for track work. :D

Anything to help keep the diff cool is a good thing. The bathurst gtr's had diff oil coolers.

Ive got a cusco 1.5 way and it doesnt squeal the tyre's at all when cornering it just clunks and bangs all over the shop any idea how I can adjust it?

It seems to fry the tires a lot better than my old stock diff and I seem to have a lot more forward thrust aswell but it doesnt make the tires squeal around corners like the bosses 33's diff does (SA guys will know what Im on about)

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
