So what makes you think the 4wd is not working then ??

The R32 will slide the back out when doing ..err... spirited driving .

If you are expecting it to handle like a WRX , ie. fairly neutral then you will be mistaken.

It will also spin the rear tyre a bit then the gauge should shoot up as the front engages on a savage launch.

If it is very slow to rise or only rises a bit , it may need bleeding or at worst the clutch packs may be gone in the transfer case.

Cheers

Ken

Jay, As Ken points out the GTR isn't a constant 4WD system, it's active, and transfers torque to the front wheel when the rear starts slipping. If in doubt take it to one of the import workshops and I'm sure they'll tell you if it's working ;)

ATTESSA is a reactive system, so it is only ever going to try & catch up with what you are doing.

It can be air in the system, but it also (Don't want to alarm you) can be due to wear in the ATTESSA clutch plates. When these gets tired the system still apportions torque (or tries to) by using the same clamping pressure as before, but it no longer works properly because the wet clutches slip more than they are supposed to.

Best bet is to get the system bled, then check it by a back to back test with a known good unit.

Thanks for the replys. I know that the gtr 4wd isn,t constent like a wrx but when i try to do a launch at 5000 rpm it just spins the back tires, also when the car gets full boost in second gear at 5000 rpm it spins the tires all the way to 7000rpm. I've noticed as i have been driving when it usally spins in second gear at 5000rpm it got full traction 4 times. So do you guy's think it the ATTESSA clutch plates?

It could be the clutch plates, or the system may need bleeding. Best to take it to a good workshop to get the system bled, if that doesn't work then you may need new clutch plates, but that won't be cheap.

How much do u think it may cost??

The two issues (Gazza's & gaygtr's) are diferent.

Gazza - yours sounds for all the world like an electronic problems - in which case the ATTESSA module under the parcel shelf should be blinking away trying to tell you what is wrong.

JayGT-R's is, like has been said, either a bleed issue in the attessa or worn clutch packs. Take it to someone who knows the systems & just as importantly knows what to expect from the ATTESSA system in terms of performance.

Yes how did u know?

The guy says he wasn,t aware of the problem.

get some pics up!!! this thing sounded like it had some gear on it. have you found out what turbos are down there?

i spoke to the owner for around half an hour on the phone cause i was going to drive down there to see it. i asked him about the faults on the car (to save me driving 3 hours and being pissed off) and the first thing he said that it was only running the rear wheels. he even said that he had got quotes from a workshop in bunbury to fix. wasnt aware? pfff no way!

seemed to be going for a good price too :)

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
