Been asked a few times before i know.

What is the difficulty in doing it?

Say u have an engine with the pump on it, and u have a rack - what else do u need? I have a spare mk5 power rack - does it just need modding to fit?

L.A.M.A.

Very difficult.

Mk 5 is full different from mk 4. You need complete steering or better complete front axle.

Sorry for bad english.

I have seen these conversions done - one came up on Ebay a while back and I'm sure it used a rack of some kind of Peugeot - a 305 I think with a Mk5 CVH PAS pump.

You can't use a Mk5 rack because the mounting system is totally different

I just put a mk5 rack and a RST rack side by side yesterday and made the following observations:

The threads for the rod ends are coarser on the mk5.
The rack is of similar length from inner joint to inner joint.
The mk5 rack is ~10cm longer from the end of rod end thread to the other end.
The valve assembly is surprisingly compact in the mk5 rack which is nice.
The take off for the steering axle is a good ~6cm more to the center line of the car.
The diameter and number of splines is totally different in the mk5 rack's steering axle take off.
The angle of the take off was the same.
The mounting to bulkhead would need a simple adapter assembly.


Still the best rack I have seen is the Nissan Bluebird rack. It's also only 2.5 turns end to end. The mk5 was over 3.

What about a Corsa?

Using a power column will still leave you with the horrible 4.5turns from lock to lock. For instance the Nissan Bluebird rack has only 2.5.

Doesnt a Shitroen Paxo have electric power steering?

JesseT

Most newer french cars have an electrically assisted column.

any more info on it ??

I don't know about being back from the grave so to speak......time will tell though

Rick

Ok well the ends can be chopped off the mk4 and welded onto the mk5 - simple enough. u can also chop the end of a mk5 colum and weld that into onto a mk4 one.

You'd then move the column to one side when u mount it. Doesn't sounds too diffucult then

JesseT

I woudn't want to move the rack sideways more than a centimeter. I just bought a Bluebird rack and I'll tell you some measurements when I get it to my hands. I once measured one that was still in a car, and it seems like it might bolt to the RST bulkhead directly. Same kind if bolting clamps with equal spacing.

It seems that the BLuebird rack is used in mk1 Golf PAS conversions. There are a lot of pictures available from the mk1 golf PAS conversions on the web.

Rick

Cool, that would be great. What about sierra stuff, cossie's are 2.x aren't they?

So does the corsa power steering work diff to every other rack and pinion rack then ?

Corsa is a motor not a rack...

Its a Leccy motor...
So the S2 lock to lock never changes

We are developing this for the S2 already....
