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.

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s

      It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.

      RB25DE NEO with Haltech ECU

      Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.

      It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
