What would happen if one removed the rear steering rack with the lines that run into the "junction box" (I've got no idea what to call it!) and simply put 2 bolts into the holes that the lines came out of?

The power steering pump rear rotor would fail

:) cheers :w00t:

Alright guys i took some pics just before (meant to post earlier but got stuck into wiring up the new battery feed >_<)

The hose i got was heater hose as it needs to be oil resistant. And yes i do know there aren't any clamps on the new hose yet, i still have to get them :D

Hope that makes things alot clearer. If you want any more pics, let me know

Hmm...

I recently had the rear steering rack removed and one of Geoff's HICAS lock bars fitted. Where the two hoses were removed along with the rear rack, bolts were inserted to plug the open threaded fittings. I assume from your post Gary that this isn't the correct way to perform the job and will need a hose that runs between these two points in order to keep the fluid flowing?

ok, i have compltely removed everything that looks like or even smells like hicas on my car....First remove rear rack replace with the lockbar...rip out every power steering line that goes to the back of the car and just follow them where they go into the valve system near the plenum...you can completely remove the valve system no worries....remove the pipes that is meant to be a cooler. remove the hicas resoviour, buy a r31 steering pump a a 3 slat belt to suit. you will need a spacer to space the pump away from the block a bit to clear the cam cover....i used a s14/r33 power steering resoviour, all the pipes hook up nicely to the pump from resoviour and steering rack....ok now under the rear parcel shelf there is a silver box that is the hicas ecu...you can unplug that....Now once you have hooked up the new basic power steering system with the r31 pump and new resoviour....you will notice you have very jolty steering and it will be hard to turn the wheel backward and foward quickly and it will feel like shit.....this is wher some people dont know about...BUT if you look on the actual steering rack iteself you will notice that there is a electronic valve on it on the drivers side with 2 wires coming from it....unplgu it and unbolt this solenoid...Watch out cos fluid will piss outta the rack....then you will see 2 holes in the rack that the fliud comes out of what u need to do now is get some steel or alluminium sheet metal only need enough to cover those holes...so cut out a peice and drill 3 holes to bolt the plate to seal these holes.......once sealed you will have very very light steering...make sure you fill the resovoiur up full when you start the car and then watch the fluid or else the steering pump will sound like its scrapping things...and top up as nessecary. NOW what that little solenoid on the steering rack does is bypass the fluid from the rack back to the resovoiur so that you dont get much fluid in the rack creating hard steering....once its covered the fluid stays in the rack causing very light steering....

Anymore questions about it just pm as i have done it all myself.......also i weighed up the sutff that is removed and subtracted the new stuff put in to make this work and it works out to be a 21.5kg loss of weight......so really youll go faster and use less fuel :dry:

What a timely thread discovery! I just pulled all my hicas stuff out of my cefiro as the previous Jap owner had put a lock bar in. He only put nuts on the ends of both hydrolic lines that use to go into the rear Hicas rack - meaning there would be an obvious build up of pressure at the rear end of the car as the fluid couldnt go in a cycle. Let it be said that nearly every seal in my main steering rack must be fked, as i go thru more power steering fluid than I do petrol.

Im currently replacing my steering rack with a s13 or s15 rack, and I will most likely put a tranny oil cooler in and run the rear part of the pump to that.

Im yet to comprehend what sort of piping and fittings i'll need to do this from reading above - but if someone can assit me that would be great.

My idea is to have the rear output of the pump go to the cooler - using about 1m of hose, then from the cooler back to the HICAS resovior. But will this still have too much pressure going back into the resv? I dont want an explosion of fluid everywhere if I can help it!

thanks!

i just thought i'd get someone to clarify this before i start hacking away on my power steering lines.

on a r32 gtst, looking at the hicas solenoid in the drivers side of the engine bay...

Line 1 goes from oil cooler to hicas solenoid.

Line 2 comes from bottom of engine bay into the hicas solenoid.

What is the best way to make the connection to line 2? there are no rubber hose sections that I can find, they are all metal screw fittings. Do I unscrew one of the fittings and just hacksaw the screw bit off? What's the best way to approach this?

From what I understood of what sydneykid posted, you can just hoseclamp the rubber hose onto both line 1 and line2, but i can't find where on line 2 that this can be done without hacksawing off one of the screw fittings.

    • 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.
    • 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...
