acutally, a easier way of doing it to remove the back cover on the pump, and remove the little vane/pump/thingy inside. it slide right out so you dont need to machine anything.

then reassemble the pump and block off the outlet.

It doesn't look as tidy thought does it? :cheers:

Why?  I use the rear stage (no HICAS) to run power steering fluid through the cooler.:P

Hey SK, how have you got this all plumbed up? Have you removed the HICAS pump, and are the lines running from the Pwr str pump -> cooler -> reserviour(bypassing the hicas pump completely)?

I'm having a look at mine at the moment, and can't decide what the easiest way to connect the line from the pump to the cooler is :confused: have you used the standard line that runs past the sump to run fluid to the cooler? or put a new line in?

Any help appreciated

:P

i think what SK was talking out was, instead of blocking the hicus outlet, you connect it to a cooler.

basicly its          hicas pump-->cooler-->reserviour

therefore the ps pump does the steering, and the hicas pump does the cooling.

That's the concept, but it is actually even easier to do.

1. The pipework that comes from the rear (HICAS) power steering pump goes under the engine and up the inner guard to the HICAS solenoids under the brake master cylinder. When you remove the solenoids, leave the pipework under the engine.

2. When the hydraulic fluid comes back from the rear steering rack, it goes through the power steering cooler and back into the reservoir. So when you remove the rear steering rack and the pipe work from front to rear, leave the pipework that goes around the radiator to the power steering cooler.

3. Connect the pipe in #1 to the pipe in #2 using a peice of 1/2" rubber hose, so that the power steering fluid comes out of the rear (HICAS) pump, under the engine, through the power steering cooler and back into the reservoir.

Simple:cheers:

PS; one day I will take a picture of the R32 GTST set up and post it up, save thousands of words being written.

so i've spent some time with an advanced image ceation tool (mspaint :)), and drawn up some pics.

Firstly, is this how the setup is before it is modified (i'm going from memory here)?...

And secondly, is this where you've joined the hose (ie - hicas pump removed completely)?

Hi,

I went ahead and removed the rear vane from my R32 GTSt steering pump. When you open it up at the back the van looks like a small steel wheel with a number of slots cut out of it where a number of little steel squares slot in. I removed this whole component but have later been told (by SSS at Girraween) that I should have removed the little sqaures and re-installed the wheel.

My pump is f'd at the moment. I assume because I did not re-install the wheel (maybe the tension on the belt was too high?) - don't know.

I want to take this opportunity to install a single chamber pump - has anyone installed an RB30 pump? Is it a straight fit besides swapping the pulley over? I think I heard that I need to put some washers between the bracket of the pump and the block of the engine to space it out because of the twin-cam head. Is this the case (it doesn't sound right to me).

Thanks.

Hi, I'll be removing the HICAS probably this weekend if everything goes to plan.

Just wondering, would it be possible to hook the rear outlet of the power steering pump directly to the second inlet/outlet on the power steering reservoir instead of blocking it?

I can’t use the SK’s idea of using it to run power steering fluid through the cooler as it is leaking somewhere.

      Well, yes, every CU on the bus is available via the Consult port, but whether the scanner you are using is capable of talking to the TCU, the ABS/TCS modules, etc etc, is what is at question here. Many of them are only for engine codes. So, if you have one of those, you won't know if the ABS is having a bitch.

      Wheel Sizes & Offsets For Skylines

      By GTSBoy · Posted

      That's now. R chassis Skylines come from a time when the tolerance in the ADRs was a bit more....slack. My car, on 235/35-17, which is damn near the exact same size as the original 205/55-16, is pretty much bang on correct indicated speed across the whole legal range. That's demonstrated with constant speed run over 5km, and GPS speed. It's just the luck of the draw. My particular speedo head has to be the thing that is "calibrated" that way, because everything else (the diff ratio, the gearbox and the speedo drive**) are all same same as most other Skylines. **OK, so the speedo drive is a Navara unit to drive the R32's cable, not the electronic unit than an R33/4 would normally have with teh same gear on it. Otherwise, I applaud your OCD tendencies, and I would do the same if I needed to.

      Not too sure, I believe the Nissan consult port does everything? Also just filled up the reservoir to full and the light is still on. The float seems to move up and down fine.

      The speedo's can be very conservative, when my Mazda NC MX5 speedo is showing 118kph, the GPS, and a calibrated radar.... cop mate.....hits me at around 110kph +/- 1 or 2 kph, and that is on a 215/45 17, stock tyres size is 205/45 17 as well, so weirdly conservative with stock tyre size When my Commodore speedo red 116kph GPS had me at 110kph on 255/40 17, so again conservative Google says manufacturers need to set the speedo from 4 to 10% slower than actual road speed.....for safety.....and compliance  After doing some offset and clearance measurements to see what can fit the NC on 17x8 +40, without guard rolling or rubbing anything at my current ride height, I've decided that when my tyres are toast, I'm going to fit 225/45 17 and see where that gets me IRT actual speed of my speedo and GPS/radar From the online calculator I should be still be doing around 5kph under an actual 110kph when the speedo is showing 110kph My ADHD requires that when I'm doing 110kph on the speedo, that the actual road speed is actually really close to that, and not alot slower And going from 205 to 225 still keeps the car within the %/mm allowable in the NSW vehicle rules and regulations, which is nice, as long as I'm looking at the latest version that is.....LOL https://www.nsw.gov.au/sites/default/files/2021-02/RMS-13.464-Light-vehicle-modifications-Vehicle-Standards-Information-No-6-November-2013.pdf

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
