Electric power steering pump conversion.
Discussion
Hi Peeps..As the title say's..Has anyone done this or know how to..I have read some info on it and it seems to either be a unit that fits into the rack itself or one that has an ECU and column sensor..Can they be adapted for a 1982 TVR tasmin 280i?..Mine has a Cortina mk5 PAS rack with a TR7 steering column..At the moment im seriously considering ditching the power steering altogether and fitting a manual one to free up some space for a supercharger...If it is feesable i would like to know what would be the best pump and fitment please..Cheers...Ziga
Hi Mark
I look into this a while ago for another project I was thinking of doing.
It has been done as Tuscan racers have retrofitted them to there cars!
You can find systems for sale on f-bay the favorite is VH Corsa, which is the neatest unit around. Small pump/tank in engine compartment, with a ecu attached to steering coloum!
When I was looking there was not a kit specially made for what you want on the market. You will have to adapt some other system to work!
But it has been done, try Topcats as they I believe have done it to there Tuscans!

Thanks Andy..I have looked into the corsa pump's and apparently failure of the pump is quite a common occurance, In fact i have read quite a few articles as regards to electric pumps packing up..Refurbed or new is the only answer but they are not cheap..I think it may well be more practical for me to buy a new/refurbed manual cortina mk5 steering rack for 100 sobs and sell my reconditioned rack with both pumps and bracketry..I should get a good price which will pay for the manual rack + fitment there should also be enough wonga spare for a custom bracket to fit the alternator on the other side of the engine and a few beers..At least this way it wont be costing me and as dix say's..Arms like annie...
..Whoops..I mean arnie...Cheers for the info...Ziga
..Whoops..I mean arnie...Cheers for the info...Zigai know the cerbera boys have fitted saxo pumps with reasonable success, small unit and believe its a hydraulic system with electric pump so works with just the ignition on.
i've played about with corsa ones before, they become heavy going one way but you can reset them but you have to be careful as they will start to turn on their own so you have to be quick and turn off ignition before they go too far!

Hi Mark,
Wonder where that Idea came from, there are two options;
1. is the wet PAS system driven by a 12v pump which means you retain your standard PAS rack and column but the oil pressure is generated electrically. On the Saxo pump it's just a 12v feed at approx 50A so you need heavy wiring and a suitable relay off the donor.
2. is EPAS where the column has electric assistance built in, this is the Corsa type column which also has an ECU and needs a speed signal or conversion box to either alter the assistance based on road speed or via the position of a manual control knob.
As you already have PAS option 1 seems easier / cheaper, option 2 is more suited to a car without PAS fitted at all then all you do is change / modify the column.
Hope this helps...

Hi peeps...I have decided to give the saxo EPS a try..Would anyone know if the union on the outlet is the same as what would be on the original system..(Montego pump)..Which i think was a 19mm fitting..Cheers...Ziga
You will need to get some new hoses made up with the correct unions, most hydraulic engineers can do it for you, takes 5 mins and cost £20.......cheaper than buying off the shelf items!Chedder
...Cheers...ZigaMine came complete with fuses and relay on a loom, all you had to do was add the switched live (ignition) and main power supply (battery) and an earth.
The pump bracket was modified to fit the front chassis cross member and the small reservoir was mounted high up on the front of the wheel arch under the bonnet,
No rocket science needed, as its all quite easy to work out, the beauty of this set up is that you can fit the pump almost anywhere as long as its lower than the reservoir.....so its ideal for Zig and his soon to be Superchargerathon!
