Hicas Removal Issues

Hey i've searched around and found Hicas removal for GTR etc, but nothing specific to cefiro, 32 etc.

I'm in the process of removing my hicas lines, as i've had a lock bar fitted and blocked up the lines, and since then i've done a rear cradle swap also. so basically i want all the lines gone completely.

Started by removing all the plenum etc, to make life a bit easier.

1 - Start off with a pic of the hicas unit in the engine bay.

2 - Next there are 4 lines going into this one area, what is this going into? is it the steering rack (i've read that the hicas has nothing to do with the steering rack in other threads).

Can i simply undo all 4 of these and put bolts in them to block them up?

3 - This is how my hicas has been blocked off for the past 2years. I'm wanting to remove all the lines completely.

4 - Following the blocked lines up toward the engine bay, i came across this joiner/block with the lines running into it. What does this do and once again is it simply a case of removing it.

5 - Up further from this joiner/block the 2 rear lines go into this spot where the 2 lines from the hicas unit go into also (same part as pic #2). once again - simply remove and block up with bolts?

5 - post-9092-1180423847_thumb.jpg

6 - Back in the engine bay i've now got the hicas unit again. the front line in this pic runs down the front of the crossmember and into the rear of the power steering pump.

6 - post-9092-1180423865_thumb.jpg

7 - At the rear of the power steering pump is the hicas line. Can i remove the line, remove the pump's wheel (HOW DO I DO THIS???), and block up with a bolt?

Thanks again for your help it is EXTREMELY APPRECIATED!!!

cheers

2- Four hicas lines on the steering rack, this is simply a connection point for the hicas lines, you don't even need to plug them up, just remove the lines connected.

4 - Trace the lines from where you have blocked them right up to where they connect to the steering rack, removing any connection block things along the way

5 - Same picture as 2? Just remove those 4 lines, I don't think you can remove the block. Also, that looks freaky with the guy in the background of the photo.

6 - Should only have 2 lines left at the hicas unit now, 1 is supply from the pump (high pressure hose) and one is return to the reservoir (rubber hose with clamps). Remove the hicas unit.

You have a couple options with the hoses.

You can disassemble the P/S pump and remove the internals to the hicas side and plug the outlet, you will also need to plug the hicas return on the reservoir

Or, what I did was get a power steering cooler off an R32 and using the old hoses from my hicas removal, piped it up between the spare outlet on the pump and the spare inlet on the reservoir.

Yeah, the simplest option in regard to piping is a non hicas pump and reservoir.

But you would have to go to the effort of replacing your pump and reservoir, and buying them (money).

As simon-ae86 said, the cooler offers more reliability, plus you don't have to pull your pump apart or replace anything.

I was mid way through my engine conversion when I did my hicas removal. But the power steering stopped working, turns out the pump was rooted, but I thought I had stuffed up the hicas removal somehow.

Just make sure you don't run the engine without power steering fluid in the reservoir.

      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.
