While keeping my mk2 std looking i do want to make it a bit nicer to drive and want to fit electric power steering Has this been done ? i guess it has, so is there a thread anywhere on a build Also would anyone recommend a set up. The Corsa eps pump is widely used on fords and even in rallying now, plenty of aftermarket hardware to adjust the asistance too I would prefer to keep the parts VAG if i could, does anyone have any suggestions ? Steve
Could you get one of these to fit? I had wondered if it would go on a mk2 with a bit of tinkering. Looks similar to the original rack mounting points.
I would recommend that you use the standard hydrolic equipment, because in my experience (alot of experience with steering) the electric stuff is total cr*p the mk5/6 rack as shown in the post above will not last anywhere near the amount of time hydrolic parts would.
I thought about using regular golf P/S but want to do something a little different without antone seeing it as i want to keep the car looking standard The vauxhall setup uses an electric motor on the actual column, so it would not be seen unless you look really close This is a setup in a vw transporter
I wont be buying a pre made kit, i have the resources to do it myself so i guess i will start collecting the parts needed
If you want to do somthing different how about using an electric pump from a Polo/Fabia and a normal rack I know from experience that the quality is not there with the electric motors, plus IMO the steering never feels right.
Theres a mk1 4x4 r32 build thread in members gallery and he's used a vauxhall corsa electric steering on the column. Personally I think electric is to light and provides little feel. MK2 is spot on IMO.
Guys, anyone have experience with using an electric pump together with the normal MK2 PAS rack, as natureboy suggests? I've heard of people using a pump from one of the French car manufacturers (can't remember specifically which) with success. However, those ones I'm seeing on eBay for VWs / Seats (particularly Polos) look like a nice compact little unit. I'm particularly interested in this idea because the particular engine conversion arrangement I'm planning on doing will make use of the normal PAS pump very difficult, and using an electric pump would really solve some problems. The pump I'm seeing a lot of on eBay for Skodas, Polos, etc. has variations of the following part numbers: 6Q0423156AB 6Q1423051AN 6Q2423051AA
Trev those pumps have there own ECU with a steering position sensor and a CAN connection into the rest of the car. I'm pretty sure they don't work without the CAN, as they switch on with a CAN signal (could be wrong) My polo used this type of pump, and in the 2years I had it I went through two of them. They are expensive new, although there are a lot of recon one's. When the first one failed it created a fault on just about eveything on the same CAN line. I had alsort of warning lights come on. Although knowing your electronic skills, you could probably get one to work, varying in feel with a speed input with megasquirt
Its easy to say this if you have never tried a modded system A friend of mine has a Mk2 escort with a corsa pump/motor and a regulator a bit like these http://www.ebay.co.uk/itm/CORSA-RALLY-ELECTRIC-POWER-STEERING-CONTROL-CONTROLLER-UNIT-/220982102436?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item33738f49a4 This gives you adjustable assistance and you can get it to feel just right i am off to the local breakers yard this coming week as i have a week off work so i will start collecting all the bits needed Steve
Hey Gareth, What about perhaps modifying the pump so that it just runs continuously, like a mechanical pump would? I wonder why they use a position sensor. Perhaps to shut off the pump when not steering for economy or thermal reasons? Their output varies with speed, does it? Do you still have any of your old units? Although the CAN side of things could be reverse engineered and perhaps be driven with a custom controller, I'd probably be tempted to just modify the circuitry and remove the CAN stuff so I can feed it with a good old fashioned RPM signal.
I saved a bookmark about the polo setup. I think this is the link, but it's not working correctly for me at the moment. http://vw.nate-online.com/techdocs/Electro-Mechanical Power Steering.pdf I think they do vary with speed. It had a great feel to it, wasn't over assisted. Maybe I was unlucky but the steering wasn't reliable. I think I have thrown the old one's out, I'll check though I'm still going to try with a electric saxo pump. But as you know it's not going to be for a while
That Saxo one is a great fit the way you have it there. I remember you showing me that. Did you actually know of anyone who has used one with success? If we're pretty confident it's going to work, we'll each be needing a custom high pressure supply hose made up, so perhaps we could measure up and get two made up.
I don't know anyone thats used it. Maybe it won't give the right feel. A friend is convinced they used the same pump on a touring car he used to work on, he said it was mounted quite far back in the car with long line's and never caused a problem. They also had it wired so it came on with ignition, so you could switch it on to help push the car around. The pump isn't made by Citroen, I will have to check who it is made by. I'm Not going to recomend it till I've tried it, it did look like it has the same hose fittings too. I'm going to be fitting a standard pas setup to the daily mk2 in the not to distant future, it would be easy to connect up and power off a battery to test on the drive.
I have found a good thread here, a saxo pump fitted to a TVR http://www.pistonheads.com/gassing/...83785&i=160&nmt=V8S+Rebuild+begins!&mid=83785 It also mentions the pumps are fitted to "Sagaris / Tamora and a few other late cars I think." Now TVR's and Citreons are not well know for being reliable, so maybe it's not such a good idea And one mounted on a T25 http://www.teamorchard.co.uk/?p=207
Its funny you should say that because a friend of mine fitted a Saxo pump to a TVR because replacing the standard pump was an engine out job, the car felt good but i wouldn't say that the electric pumps are reliable but at least you are using hydrolic PAS which should give feeling like a belt driven pump.
Thats interesting and good to know. Engine out job ouch. My main reasons for using the pump is because I'm doing a 16v G60 conversion, and it should help make the pulley setup on the engine simplier, and hopefully help keep the bay tidy.
Due to owning a saxo as well as my golf i can honestly say the saxo pump is highly unreliable but as they are 10 a penny id say they are worth a look. personally after the third pump failure on the saxo i have left it without power steering and i actually prefer it, much more precise and predicatable.
