Did you remove all the electrics for the hicas as well? The hicas module controls the power steering assist, so if there is a problem with that, or if it isn't even there anymore, the steering will always be heavy.

If the hicas electrics are still in there and working, did you reconnect the solenoid on the steering rack when you changed it out? Does the steering start off light and then go heavy after a few minutes? Why did you change the rack and pump anyway?

Same prob happened with mine last week. HICAS has been removed for years with no problems but now steering starts off very light for approx 1 minute then goes heavy. Have not checked it out yet but if someone has experience with diagnosis then I'm all ears!

Possible stuffed solenoid on rack??

I left all the electrics for the hi cas

i disconnected it but it still has heavy steering

i plugged and unplugged the solenoid on the steering rack but did that nothing

i also plugged and unplugged the hicas unit in the boot but that did nothing

the steering is constantly heavy

i changed the rack and pump thinking that it would fix the problem, but i guess not

could there be a blockage in the lines?

i also get a weird noise when i move the steering wheel to a certain point, sounds like air coming out

any ideas?

Ha ha. I get the same noise. Thought it was just extra noise being allowed to travel up the steering column after installing an alloy steering block in place of the rubber one.

Where is heller44? Looks like he had some answers!

I've been playing in the red dust up north, no net access for monkeys up there.. only flew back in tonight.

I reckon you both have very different faults to each other, andrew yours looks to be a fault condition with the hicas unit, so you need to do a diagnostic on the hicas, look in the tutorial section for the procedure on how to do it, it is a pain to get it right but you should be ok.. count the flashes and work out what part of the system is faulting.

Dfault, yours isn't even starting out and then faulting, probably throw a multimeter on the pins for the solenoid on the rack and see if you are getting any voltage there at all. Possibly where I would start.. nice easy check anyway. Once that is done you can go from there and see wether it is mechanical or electrical.

i have this same problem in my cefiro

non hicas model

on the drivers side i still have this solenoid looking thing with 4 hoses ( i unplugged that )

then i have this senson down near the drivers wheel ( i thought could be a speed sensor that adjusts steering tension at high speeds )

and lastly i wound the nut out on the rack ( adjusting one )

done all that at same time and my steering is slightly better lol

just dont know what one made difference, its still heavy as thou !

Thanks heller44!

No HICAS globe in the dash as it was taken out when I removed the HICAS system many years ago (rack, oil lines to front etc).

Now that I think about it I'm sure my speedo stopped working at the same time. Would it be fair to say this could be my problem seeing as the steering appears to be speed sensitive? Honestly was not aware of speed sensitive steering in R32 and thought that as the R32 uses a speedo cable it would not be able to have a speed input to anything else on the car. Would be awsome if I'm wrong and my inoperative speedo could be causing my dramas!?!

*facepalm...

no speedo, no speed sensitive steering.. sheesh. mechanical cable drive from the gearbox sender to the cluster, built into the back of the speedo itself is something like a tacho generator that transmits a speed pulse to both the hicas unit and the ecu.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
