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.

    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
    • LOL, all of the CAI like Craig I just need to put a hole saw through my bumper Done and dusted, the car runs, which is nice, I'll take it for a spin when the weather clears up Just need to put the bumper back on for good
    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
