No HICAS on any of our Skylines, our ace team fabricator makes up the rear rack replacement. There is a picture on a previous thread on HICAS, do a search, it is well worth reading.

Hi Sydneykid;

I'll follow up that thread for sure. Cutting to the chase though;

Is that no HICAS on any Skylines street or track ie you'd advocate removing HICAS full stop?

Like Hiroshima Screamer I'd like to know please if there are any negative effects of removal (from memory I think you said once that the pump lines make good fuel lines so I guess that implies that you strip everything because it becomes superflous weight).

Can I take it that the wheel alignment specs you posted recently (for Enrico I think) are those you suggest for non HICAS cars?

Thanks for any advice you might be able to provide.

Cheers

I think Skid meant all his skylines have the HICAS removed.

Another kit option is available. It consists of a piggy back for the HICAS computer and two lock rings to make rear rack solid. The down side is no extra fuel lines and still quit a bit of additional weight.

Upside is if you want to put it back... too easy.

Hope it helps

yeah did it myself. i got the tomei kit. its pretty easy to do, just back the car onto ramps and that will give u all the room u need.

Greg,

I too have the TOMIE HICAS lock kit, but it wasn't as easy as that to install.

- Basically we had to put the car on the hoist.

- Remove the rubber covers on the Hicas.

- Unscrew one of the controll arms from the HICAS and attach one of the TOMIE shims in position (leave controll arm unscrewed).

- Get the car in HICAS diagnostic mode (From the moment you turn the ignition you have 10sec to: turn the steering wheel 20deg. left and right, 5 times; then press the brake 5 times.)

A REAL PRICK, especially when you are running a aftermarket ECU and the car takes that extra second to start up.

- Once in diagnostic mode the HICAS light on the dash flashes.

- Rev the engine to 2k rpm and turn the steering wheel 180deg in the direction of unscrewed controll arm. This will push out the attached controll arm.

- Attach the second shim, in it's designated position, on the second controll arm.

- Turn the steering wheel back to the neutral position. This will cause the attached controll arm to be pulled into the HICAS, locking the shim into place.

- Reattach the other unscrewed controll arm, also locking the shim in position as you screw it into the HICAS.

- Place the rubber boots back in their original position.

- Turn off car, disconnect plug at the rear of the HICAS mechanism and lower hoist.

- Disconnect battery.

- Install little black box as instructed.

- Reconnect Battery.

- Installation complete

(Sounds harder than it is, just getting into diagnostic mode is a little tricky)

SK, I did a search, but couldnt find it:( perhaps the thread is too old?

any tips for replacing hicas with a lock bar on an R33, I got a lock bar today (thanks ender), and want to fit it ASAP

cheers

Steve;

Try using advanced search and look for HICAS and Sydney Kid in the subject and posts sections. Comes up with a small number of threads and the one you need is not called HICAS.

Guys I fabricated my own replacement bar from mild steel and installed it, then went to the nearest place for an alignment.

The result for me was noticeably improved control at and beyond the limit of tyre adhesion, however I now have to install sub frame lock rings as the rubber bush deformation is highlighted to a greater extent. I can feel the rear move away from the corner before it responds.

The downside is the Hicas light is on but I will remove the bulb when i get around to it.

I'd be happy to supply anyone who wants one for a reasonable price, say $100 including delivery and I'll make a donation to SAU of $10.

No pics but the bar is just a holllow bar with 2 tabs for attachment, one elongated for ease of alignment and threaded ends for the tie rods.

I'll put together instructions as well as there is an easy way to install and a hard way.

well, I bit the bullet and had a go at fitting my HICAS lock bar, only to find the threads were tapped for the OTHER end of the tie rods :) so had to put it (the HICAS) back on, and now I got to try and find someone who can tap the lock bar out to the correct thread..... pretty funny really.

But it is very straight forward and only requires a 30mm spanner ( or a shifter ) and a 19 mm socket.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
