Gday all

My hicas is getting pretty noisy so i think its time i do something about it. I had one lined up to buy about a month ago but fell through :-(

I have found another for sale but its off a r34gtt, would it be the same, length and senors?

Any help would be appreciated

Cheers

i put a r33 gts35t one in mine . well i would have . the stagea one has the motor pointing down (FAIL) the r33 one has the motor pointing backwards way higher up .. the plugs and sensors are all the same . a skyline one will bolt in but 1 or 2 of the plugs are to short by a couple of inchs

have you checked the 4 ball joints ot the two bolts that hold it to the subframe ? gievn the amount of work the rack actually does i highly doubt its worn out

jack ut up and get some gorilla to try and "steer" your back wheels while you look to see whats sloppy

the noise is the actual hicas motor, it sounds like a cheap noisy fuel pump when i pull up to a set of lights or moving very slow

Sorry Punk72, I get a bit slack some times. Send me a PM $20 should cover freight and it yours

I actually posted a month or 2 ago about my replacement hicas bar being too short

It is suppose to be a R33/34 hicas lock bar

I measured it tonight

The stagea hicas rack is 425mm long

The hicas bar is 405mm long

So this was giving me major toe out

Will have to sort it out tomorrow with Justjap.

hicas does nothing below 80 kays ???????? .

put it in hicas diognostic and it will make the rear wheels go max letf to max right and back to centre every 2 seconds while the car is stationary so you can look under it and see what it is

Just because the hicas isnt in use doesnt mean its not running? i have pulled up and it was still doing its noisy thing so i jumoed out and felt everything around the hicas area and the

only thing that was vibrating was the black motor looking thing in the hicas setup.

I am going to have to give this diagnostic thing ago and see what happens.

cheers

update on this hicas problem,

bought a r33 hicas motor and swapped it over, noise totally stopped for a good hour of driving around town, then slowley came back getting louder and louder to the same as before :-(

In the mean time I have been searching the web and found a couple of pages say that if there is any problem ie motor or sensor stops working the hicas is unable of moving make it from 4 wheel steer to 2 wheel steer,

So I disconnected the motor and took for another drive, No noise!!

Has any one done the same for a long period of time and found any change?

another update on the hicas problem

bought a set of tomei hicas shims for $80 and locked the bloody thing off, gutted one of the spare motors i had and put it all back together.

looking at it you cant tell the difference everything is plugged in and looks stock.

noise has completely stopped and the car feels a lot tighter.

and removed the hicas dash light

I pulled a r33 hicas rack apart to see if i could find anything that would cause the noise, but only pulled half of it apart as i didnt have the right tools. One day

    • The HG high flow is excellent, and costs about the $$ you're talking about. But it, and probably every other highflow, uses a diffeent core than the original turo, and the original Hitatchi core is quite long. So, I think it is inevitable that there is likely no such thing as a highflow that just "bolts on" with no other effort required. And the same is likely true for HG's outright replacement "bolt on" turbos (the ATR things). And the same is likely true for anything similar from elsewhere. I have no idea if the cheap Chinese/Taiwanese complete turbos from eBay/Temu/etc are as bolt on as they claim. I mean, they claim the bolt onto the NAs as well as the turbos, and we know that can't be "bolt on". But it wouldn't matter because I'm not buying a $169 4 psi turbo for anything other than a paddock basher.
    • Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD? 
    • Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.
    • So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
    • OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
