Hicas - Im Very New To This Car And Would Love Some Input


Recommended Posts

Hi again, i know this topic has been covered abit in the past and ive been doing my best reading through old posts hoping to find my answer but had know luck yet so i figured i might aswell just straight out ask, i bought my R34 gtt about 2 months ago, when i was testdriving it i even asked the salesman why the HICAS light on the dash was lit up and what it was for, and he just said its to tell you its working properly and then changed the subject, now all my life ive wanted a nice skyline but that doesnt mean i know a thing about them, i know this is gana sound silly but yeah i dont really even know what the HICAS does properly. I soon figured the light must be on for a reason other then what the lier salesman said but there doesnt seem to be anything wrong with the car, i dont know what i should be thinking may be wrong either, could i be causing my car damage driving it with this light on ?? I would love all the help and ideas i could possibly get on this topic, it would be greatly appreciated... Thankyou so much for taking the time to read this...... Cheers

i assume you know hicas is the 4wheels steering in skylines. if the light is on, the car may have had hicas removed or the hicas may have a fault. post a pic of the underside of your car looking at the diff from the rear. that will show if your car has had hicas removed

most people remove the hicas because it has a mind of its own and sometimes tries to do things you aren't expecting. makes driving your car hard a little dicey when you are having to correct for what the computer is doing and it tries to correct for what you are doing at the same time. removing it also saves a bit a of weight.

unless you go with a tomei hicas removal kit or similar, which fool the hicas ecu, you'll have the light pop up. these kits are exxy though and people generally just remove the bulb from the dash. free and easy.

however, do get it checked because the light may also come on for a fault with the system or orther related stuff. i have no knowledge of this aspect so better wait for other replies here or take it to a mechanic to get it checked out.

meantime, look through these two threads. the info you need is likely to be in there. btw, i got these two simply by searching. try that next time. might save you a bit of time:

    • They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required. 
    • I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.
    • I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something? 
    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation.
