Yet Another Hicas Question =d

I've already made sweet love to the search button OK!

On the way home this evening my car's steering seemed to get a reasonable amount lighter than per usual (Series II R33). I wiggled the steering wheel back and forth for a while and changed speeds (ranging from 40-110) still doing my little back and forth left right wiggle. It felt much lighter across the range of speeds completely whereas it used to feel like it was quite heavy over 100 (which felt nice).

No HICAS light has come on (other than with the rest of the lights during the ignition sequence) and a quick look under the rear doesn't yield any clues (nothing leaking nothing obviously busted etc).

Just wondering if anyone else has experience this before.

I'm wondering if something is busted or if HICAS has just started working or what, or if I'm being overly sensitive. I'll of course monitor it over the next few days and see how it feels but just wondered if anyone has experienced this before.

It doesn't help that I've got a set of 18's with much wider rubber on the way either they will stay off until I'm comfortable that all is well.

Side note, 265's should fit on the rear right?

Cheers

P.S. Is there some form of HICAS diagnostic I can do without Consult?

I beleive HICAS only operates over 70km/hr, so if it's lighter under that, then I doubt HICAS started working. It's prolly working fine in your car.

On top of that, R33's have electric rear steering instead of the 32's hydrolic setup, so you shouldn't feel any different if it STOPPED working.

I'd normally guess that you just inflated your tyres, or it was a really hot day and the air in the tyres expanded, but i'm sure you've thought of that! =-]

Randy (we meet again, you are always full of useful info for me :P )

The drive to work this morning felt fine, gave it a bit of a push around some corners at mid to higher speeds and felt some stuff going on back there.

I'm confident that you're right and that it's nothing, still nice to have someone else confirm it for me =)

Cheers

Yeah would have to agree with Randy - tire pressure can make quite a difference in the steering feel..

although - I do believe HICAS also works at low speeds to assist in parking.. but than also higher speeds as noted..

it's always fun when the car chucks in a couple of extra degrees going around a corner lol..

Actually.. A picture I grabbed from another post on this forum shows that at low speeds HICAS does nothing at all... It's Honda's and so forth that use 4 wheel steer for parking duties (because the owners can't drive). Heck was surprised how easy it was to reverse park my 33 and that's with a GTR wing, some people just gotz no skillz.

Back to the HICAS.. I did recently check my pressures (as I do weekly) and they were fine...

*shrug* While it keeps driving straight and no HICAS light I guess it's OK =\

My HICAS is always on.. for some reason.. even when i start up the car..

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
