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.

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
