I disagree, last night took mine out to a dead back road, launched from 3k revs very little tyre spin and it launched hard without an issue, redlined it through all the gears and drove quite freely and smoother around turns then my other car by far at high speed

WTF has that got to do with HICAS?  Do you actually know what HICAS is supposed to do?  It's not a traction control.

HICAS is supposed to move the rear wheels to invoke a slip angle earlier than would occur under passive drag along of the rears (caused by the front's making the car start to rotate).  It is supposed to make it feel "snappier" on turn in.  Whoch it does, as long as you're not on the verge of losing grip.  Now, that "as long as" is fine, up to about 7/10ths.  After that, as you drive harder, especially as you push right up near the limits, the rear will be on the verge of breaking free and a skilled driver will be working to balance the steering and throttle inputs to control that.  The last thing a skilled driver wants is for some 3pt IQ computer system to be raggedly sawing away at the rear steering control trying to do what it does, because it actively fights against what the drive is trying to do. It is a shit system.  Even worse, all you have to do to make a Skyline turn in better than it does with HICAS is simply upgrade all the suspension - which we all do anyway.  Some bigger ARBs, better dampers, some bushes and a decent alignment are 50x better than HICAS.

So, please consider that set of facts.

Yes i know what hicas is meant to do, its a rear steering assist unit designed to help improve handling around turns both at low and high speeds, its more noticeable at high speeds, what you describe is 100% different to what actually happened, all it did for me was improve my control as its designed to do and as i said previously it did not "fight" me for control, those are the facts, all your doing is repeating your view thinking you know everything which obviously you dont, if you did then my r33 should have acted the way you state more so for the fact that it needed an alignment when i done it last night, so it should have been worse for me, each gear change i hit my limiter everytime, from 0 to past 180 on the speedo

The road wasnt straight, just didnt have any really sharp turns but has a few bends

I think the key thing everyone is missing in your post is that HICAS is supposed to kick in hard when you are about to lose control around, say, a sharp corner, and helps balances the steering to avoid this, but from the sounds of things you weren't going around a tight corner and you weren't losing control (in a bad way) so that's why HICAS didn't kick-in as such. 

I personally find the HICAS system to be a supportive system as when I take on corners hard I can actually feel the independent rear wheel steering assist mechanism kick in which, in my opinion, can only help.

I am sure my wife's 162TSI Tiguan would perform better than a stock R32~34 GT-R around turns 

Yeah, so can my 2019 Toyota Kluger but who's comparing, right?

Like, come on man, stop adding insult to injury.

Show us a photo of the Tigs you drive :) 

Show us a picture of your wife..

 

 

 

 

 

 

 

's Tig..

 

I still have HICAS on my R33, and agree on a spirited mountain run it's not that noticeable (as GTSBoy says, 7/10ths vs 9+/10th), when i take it to the track though, it's borderline terrifying, so unpredictable. Really need to remove it one of these days.

This is an honest question - but I've never driven a GTST only GTRs...is the HICAS on both cars the same and works similarly?

Yep, I drove a R34 GT-R around Japan.. was a piece of shit.

Needed a single, and HICAS delete :)

I bought my R34 GTR with upgraded twin turbos so wouldn't know to comment on stock set up but this is interesting.

Uumm...never knew GTST's have HICAS...dumb of me, I know to assume.

That also brings into what your car is used for as well, different uses have different setups, for example, i wouldnt take a car built to drag race out drifting or track racing

why would you even build a car then?

The more money I've poured into my car, the more I've taken it to Wakefield Park to enjoy. There's simply not enough road and rules for a built car on our streets.

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
