im about to chuck my lock bar in this weekend. i have done a lock on a 32 and it was locked on my old 33 as the hicas was faulty but i must admit i never new there was a computer in the boot that controlled the 4 wheel steer.

i knew that the hicas in r33 was electronic as opposed to the hydraulic set up in the r32 skylines but yer the computer is news to me.

i have recently pulled the hicas sensor off the steering collumn when i did a steering wheel change and only thing i can notice is the light come on when i turn hard if im dring over 80!

i guess i have 3 main questions ..

1. will removal of the disc sensor set-up interfere with my power steering???

2. will unplugging the electronic clips on the hicas interfere with my power steering?

3. will removing the ecu in the parcel shelf interfere with my power steering??

i want my steering to feel just the same as stock but with out the rear wheel steer.

You need a HICAS Bosskit for your steering wheel,

Leave the computer alone and it will be fine.

The only thing you remove is the bar itself and the bulb. Leave EVERYTHING else or you will have problems.

what about removing the fuse?? where is the fuse located for the hicas? i read somewhere that its in the boot, but where in the boot? i have just put a lockbar in and it made so much difference to the handling of the car. i like i like.

i took my hicas ecu out years ago in R33 GTSt. i guess u could say the steering was slightly heavier but im also running 19" rims which weigh shitloads more than the stockers.

i also never had the hicas light come up on the dash when i removed the ecu

some ppl think its weird but it was basically unplug it all and things were normal.

Has anyone tried an RB25 PS pump in a 32 GTR rather than gutting the rear impeller? Has any one removed all the wiring from the rear (the disconnected bits) to free up some weight/clean up? Were upgrades to the caster bits necessary?

Just tape them up and cable tie away nicely.. Or, if you CBF i think you can pull them up into the boot through the big ass grommet there.

Hi guys, i have recently bought a R33 with the HICAS motor being removed, and it's got a lock bar installed.

The steering feel is stiff when car is not moving, for e.g. when trying to do a reverse parking. When driving the car at higher speeds, its still stiffer than a stock R33 with the HICAS unit.

What I would like to know is, does the removal of the HICAS unit and the installing of a lock bar caused the power steering to be stiff ? I know the removal of the HICAS unit is to prevent the rear wheels from steering and the HICAS lock bar is obviously to lock the rear wheels into a locked position. But does this naturally mean the steering should be stiff ?

Or is there a problem with the power steering unit or pump ?

Is it possible to have the HICAS unit removed + installing the lock bar, BUT still retain the feeling of a power-assisted steering ?

I am totally not used to driving this car with the stiff steering, and would like to return to the original feeling of the normal power assisted steering. I asked the previous owner why the steering was so stiff, and he told me that its because the HICAS unit has been removed. Is that really the reason behind it?

Hope you guys can help out here as I am really new but I have searched through the forums on this topic but cant seem to find out the exact answers. Thanks guys !

Hey dude,

Check in the boot and see if the HICAS ECU is still there and plugged in.

Fitting mine the steering didnt change at all. But i hear that if you remove the ECU, then it will go heavy.

so many variations with this hicas lol... i removed my hicas computer years ago when doing a boot install, the light never came on, the steering was light as usual i also got 19's with 245/265s on. recently i finally got around to fitting my lock bar. and again no issues at all.

what about the steering position sensor in the r33? located behind the steering wheel / boss kit. its the round disc with the tab that fits through the slot in hicas specific boss kits / standard wheel.

it was mentioned above that once removed, it had no bearing on power steering weight, etc.

can i get a confirmation or otherwise about removing this sensor?

hey, awesome write up...plan on installing the bar in the next week or so. Was just wondering with the wheel alignment, would you be able to do it yourself? maybe with some string? lol i know it sounds dodgy but might not have time to drive it to a w/a place for a few days...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
