Rb25 Into R32 Using Rb25 Non Hicas Pump Help

[DVS JEZ]

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

[Duncan]

fwiw, this is the fast diagram for r32 gtr power steering. but it includes HICAS and is hard to follow

here is a slightly better one from the workshop manual

[DVS JEZ]

Thanks mate. I think i might just get 2 lines made up from pirtek.

That workshop diagram helped heaps. Now atleast i know which line is pressure and which is return.

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?

[DVS JEZ]

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

[dantheman88]

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

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?

[GTSBoy]

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.

[Sarumatix]

I get that, it was more about whether there was any difference between an R33 pump and an R34 pump.

[GTSBoy]

I think they have different pulleys too - I think there are different belts, but am not totally sure, hence why I recommended R34 pump.

[dopey]

Using a ceffy pump I thought would be easier, same pulley and off a rb20. I was going to couple it with a 31 reservoir

Not for a Neo it wouldn't be.

I forgot that part, Ill go back to my corner now.
