just got an R32 GTST shell, have fitted an RB25DET and box,

all the power steer lines/pipes were given to me in a box and im trying to use the rb25 power steer pump which doesnt have hicas.

has anyone done this?

any one have a diagram of the r33 and r32 power steer system so i can see what i have to do.

cheers

by far the easiest thing to do is buy a HICAS lock bar (dirt cheap these days) and remove the solenoids, lines etc.

Then just use rb25 pump and r32 resoviour. I feed from the bottom of the resoviour to the pump inlet, then 1 line from pump to rack, and 1 line returning from pump to resoviour

This is exactly what i was needing help on for my conversion. I dont have any of the lines, I already have all solenoids removed and a lock bar fitted, so i wasnt sure how the pipes should be run either.

Because the hicas is gone, can i just run the pump to the steering rack then the steering rack to the resovior, then the resovior back to the pump?

I was thinking about getting some banjo bolts with the barb fittings and just pushing on the hose lines. what do you reckon?

Im heading to pirtek in a few minutes.

Once i measure up how i'll run the lines and what fittings etc ill post up how i did it.

Will be from reservoir to pump - pump to bottom fitting on rack (high pressure pipe or crimped connectiins) - rack to power steering cooler loop near radiator (low pressure hose and clamps) - from cooler to reservoir

Yeh let us know becasue I will be very interested to see how you go with it. I dont have the cooler section for mine so im not sure whether it would be needed or not seeings the Hicas is all gone :blink:

Sorry for Necro but...

I'm putting a NEO rb25det in an R32 and also having issues with powersteering pump alignment and HICAS removal. I have the RB20 pump, an RB26 pump and neither seem to provide any joy. Next step is to source an RB25 setup, will any RB25 Powersteering pump work or does it have to be off a NEO?

You will not be able to make it work with the old pumps on the new motor. The pulleys are different. OK, you may be able to make it work if you can find/make/adapt/space a suitable pulley.

Plus, one of the benefits of doing Neo into R32 is to get yourself some engine ancillaries, like the PS pump, that are 10 years younger than the old RB20 stuff!

So, the answer is to get an R34 pump and be done with it. After that, all that is required is to get the hoses from an R34 and attach them to the engine bay pipework for the R32 rack. Some Pirtek/Enzed assistance is required. Piss of the plumbing to the HICAS gear and throw it all in the skip.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
