i finally took my hicas out last weekend, took all the hosing, and units out and plumbed the hose back to the breater hose in the front where the 4ws actuator was, works like a dream, just have to take the hicas bulb out of the dash now...

I'm pretty keen to do this, just one question though. Is it better to lock the back up with a lock bar, or with the washers (in weight saving, and strength). I'm guessing that the washers will be fine, just wanted to double check though.

I found a HICAS ECU pinout, and wire 20 is the warning lamp, so if you cut that, it should save pulling the dash out.

Any chance you could share that pinout?

I really wouldn't mind having a good look at that.

OK.....

i have a picture of the HICAS solenoid i hope the picture can make sense for me and all the other HICAS frenzie removalist out there..

Join the hoses you marked in red and the rear stage of the pump will just feed throught the cooler.

I am confused. My lines have small hose for hose #1 , and large hose for hose #2 ....how are you supposed to join them with a simple 150mm long hose? I must have the wrong line, but I have followed the directions right as far as I know? It looks to me that #2 is high pressure...there is no-where to attach a normal rubber hose without making a fitting ?

If it is the right one, I have no idea how I am supposed to get the hose off there with the metal clamps.

The top of my engine bay looks like the picture posted by meep.

The underside looks like this

I could disconnet it under the car, then run a longer hose up, and use a fitting at the bottom...but this doesn't seem right based on what SydneyKid is saying?

I am worried I am about to rip out the wrong hose. either that or the wrong place, cause i can't see it being a 10 minute job like SK made said

Is the line in red the right place to put the link?

Let’s get the terminology right first then move onto what to do.;

1. High pressure hoses DO NOT HAVE CLAMPS, they have compression fittings. So any hose with a compression fitting on it is NOT low pressure.

2. Low pressure hoses HAVE CLAMPS.

3. What you are doing is joining 2 low pressure pieces of (standard) pipework with a piece of (aftermarket) rubber hose that has a clamp at each end to hold the (aftermarket) hose onto the (standard) pipework.

4. The fluid supply and return to the power steering cooler is LOW PRESSURE, so it has clamps.

5. Follow the power steering cooler (standard) pipework and (standard) hoses and note where the (standard) pipework joins to the (standard) rubber hoses. Note that there is both a supply from and a return to the power steering cooler, the return is LOW PRESSURE.

6. Go to the power steering reservoir and follow the (standard) pipework for the return of the fluid from the rear solenoids. The standard pipework goes under the engine, clipped to the subframe.

7. Join the output of the power steering cooler (standard) pipework to the (standard) pipework where it pokes up from the subframe. It needs around 100 to 150 mm piece of aftermarket rubber hose and 2 clamps.

Sorry I can not put up a picture, so please don’t ask.. My own R32GTS does not have the pipework in it at the moment as I am changing to a larger power steering cooler.

Hopefully that is of some help.

:thumbsup: Cheers :wave:

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
