    Default Electric power steering

    I'm about to put a 304 in my vc Commodore, I'm weighing up whether to use the 308 vc k frame with manual steering or the VN k frame with power steering from the donor car I have bought.
    Any input would be greatly appreciated.

    But that decision has raised another question of if I should put power steering back on.. The vc originally had power steering but after the 3rd thrown belt I put on the manual steering system. I figured I'd need the extra room for intercooler piping anyway.
    That being said power steering made the car alot more streetable, so I'm wondering what options people have used for power steering in a full engine bay?
    I've heard of people using Astra electric pumps for the factory hydrolic racks? Can the electric Astra pump systems be mounted in the boot with the battery?
    Or is there a purely electric system out there that works OK on old commodores?

    Any advice would be great guys.

    Need to mount a pump in engine bay to prevent hydraulic and electrical losses if mounted remotely .

    Mod plate for an electric steering pump???? Electric pump is different to "electric steering"

    Have seen at least one successfully mounted in the boot of a HQ that worked great, that was used with a HQ steering box.

    Have you considered/tried using a larger diameter aftermarket pulley on the power steering pump to slow it down? It might help with throwing belts?

    Thanks mate, I'm leaning to the boot mount pump as the battery etc is back their anyway..

    I can't really fit a factory power steering pump anymore due the intake piping unfortunately. That's why I went manual steering originally.

    What type of losses are we talking? Electrical losses aren't an issue but hydraulics I'm not familiar with. Heavier steering etc? Is that what you are referring to? I can't imagine it would change the feel very much?

    Hi
    If u no your hydraulic basics pressure is lost over distance and volume can be reduced . More of a caution of what can happen ,it depends on design .Full electric or electric over hydraulic . Once again depends on the electrics ,need correct cable sizing etc . This is precautions i would think about due to my industrial/mechanical /fitter background. Thinking out loud .

    I would mount the pump under the guard somewhere.

    add custom HD wiring to feed it ( think the Astra Pump is on a 80A feed from memory*)
    then
    custom hoses (high pressure and return) and yep, Bobs ya uncle
    electric steering


    * again from memory, the Astra pump has some sort of sensor that
    decides if the pump works or not. The battery/charging system must
    give it at least 13.9v or the pumps shuts down to prevent damage

    Thanks all,
    I might get my hands on an Astra pump and see what it will take to set it up.

    This maybe a little left field but has anyone tried to use a VE/VF electric steering rack in a 1st generation Commodore????

    good luck with that... as it needs the associated loom and BCM to work
    as well as being front mounted on the cross member

    You will need a sump change if you mount it where it is designed to go...


    ps... this style of electric steering was only on VF (never VE)
