Removed Hicas In My R33, No Power Sterring, And Very Heavy Steering!

[nsta]

Is this normal guys?, i have a series 1 r33 gts25t, and removed hicas as per geoffs instructions,and the steering is extremely heavy.

[funkymonkey]

you've lost pressure in your power steering system and most probably lost fluid too. Did you seal off the HICAS lines after you installed the bar?

[nsta]

How do you mean seal off?

[funkymonkey]

oh wait... sorry, I was thinking R32... R33's run electric HICAS usints don't they. Ignore that. Just ask GTRGeoff

hey yeah, the power steering fluid was empty!!!, filled it up, took it for a drive, and still i have very heavy steering, like no power steering. How long before the power steering fluid begins to work?, i thought it should be instant?

[sav man]

Did you re-top it up after the engine was running? As once the fluid has gone through the pipes your level will be down again.

[nsta]

no, thanks ill do that, cheers:)

[tek_01]

do as suggested above, just for the record what did you actually do when u installed the bar??

when i installed mine i did not need to do anything with fluid etc, just undo the 2 bolts holding it in and also undo the ends of the original hicas unit, than replace with new lock bar

theres a tutorial for an r33 in the DIY section

when you've filled it up, start the motor, and turn the wheels from lock to lock a few times to pull the fluid right through. Then fill resoviour back up.

As all of above but incase that doesnt help - have you removed the hicas computer in the boot? If so that could be the problem as it does not need to be removed.

I have read on here a few times of people unplugging their computers and describing same problems as you.

You only need to keep the hicas computer in on the 32's if I remember correctly. I'm pretty sure you can take them out on the 33's and 34's?

[nsta]

checked fluid and still very very heavy stering, i didnt take anything out from the boot, just took out the hicas unit and the plugs(loom) that connected to it, and replaced with the lock bar.

If the steering had no oil, then you have a leak somewhere yes?

Wont be disappearing otherwise.

I would be investigating that, its just co-incidental that it occured the same time a HICAS removal as they are independent of each other on the R33.

Could be a dead power steering pump, or a rack in need of attention. Not a lot more to is really with PS on the Skyline

well ive been reading up on some threads, and ppl are saying that when removing hicas in an r33 gtst, you lose the easy steering at low speeds, since hicas unit controls the front power steering assist?

edit: id like to add, i had done a manual conversion at the same time of doing this hicas lock, and my speedo is off by heaps, i was told this could contribute to the power steering issue, as its electronically controlled against the speed of the car, and may have just cut off altogether?
