Power Steering Question After Changing To Top Mount

Sorry I didnt know which section this fitted into. Moderators feel free to move it. Ive just changed my rb20 to a topmount setup with a gt3076r. Problem being that the power steering reservoir is too big now with the turbo there. So I thought id rip out the Hicas at the same time and change it all over to r33 gear as its much smaller...I have an r33 reservoir.

Question is: Can I use an R33 Power steering pump on a Rb20? I know the belt has to be changed but does anyone know if they line up or fit the bracket?

I thought other people with top mount setups may have run into this problem on Rb20s

Thanks in advance,

Stu

I moved the standard reservoir down beside the radiator and just changed the hoses. Thats the easy bit, as ive had heaps of issues with the power steering pump/bracket and offset of the pulley in relation to the harmonic balancer. I ended up having to get the bracket machined in a mill to elongate the mounting holes so i could slide the whole assembly back and forth to get the right offset. If i were you, i wouldnt change the ps pump, because as far as i know, theyre all different. Just move the reservoir (you can see mine in the bottom right of the pic). I ran into these problems because im using RB20 ps stuff with the RB26 engine.

EDIT: I think the changes to the forums arent allowing me to upload pics. You can see where my PS reservoir is in my avatar above.

Thanks for you reply.

The problem with that is I have removed all the hicas gear while i had the car apart. And have had mixed response when it comes to gutting the back of the r32 pump and blocking the hicas outlet.

The tally for will a 33 pump fit on an rb20 sits at yes: 1 no: 1

Can anyone confirm?

Yeah, i removed all the vanes in the rear of my pump and it works ok. The other thing you can do is just use the rear part of the pump to circulate the fluid around to the front of the car so that the fluid will cool down. Because if you remove all the hicas gear, you remove the factory piece of pipe that is used to cool the oil. Depends what your using the car for i suppose.

i'm using a r33 p/s pump and bracket on my 32 still with a rb20. It was the best way to eliminate all the hicas lines running from the rear of the car and around the front. It works perfectly. The p/s belt is silghtly narrower than the rb20 one but no problems with that.

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)

      I'd love a Haltech ECU, and Haltech 10 dash. Was having a chat with Rob and Andy @ Haltech when Rob put one in his MR2. First one I'm kind of interested in too, as you can dim it RIGHT down. Andy was saying bright dashes is one of his peeves too!
