hi i've just joined this forum, i have a couple of 924's 2.0 n/a one has been in the family for 25 years and is under going bodywork, the other is a project (getting a 1.8t)

My question is i have fitted electric power steering columns to both of them which is great for the road but my project car will be a bit quick so is there a quick rack or any parts that can be used to reduce number of turns lock to lock?

I've got no info on quicker steering racks, but I'd be very interested to see some info on your power steering setup. Any chance you'd start a thread detailing donor cars and installation pictures?

I was PM'ing with an Italian member here on the board who knew his stuff (scooby or mitsu rally transmission guy IIRC). He fitted a modified vw aftermarket unit with fantastic results...

What's your current setup? I'm not buying the "electric" setup you describe.

hi the donor car was a vauxhall corsa c 2005 , IMO its the easiest way to get power steering, the parts required are the complete corsa c column (non adjustable) and lower uj, a controller to get it working and adjust the weight of the steering and 12v supply for the motor and 12v ignition control so it only works with the ignition on

im taking the column out of the project car soon i will get some pics

it fits very well in the 924 the only body mod (appart from drilling some holes and making 3 brackets (very simple)) is to hammer a very small shallow in the bulkhead under the windscreen.

The steering shaft takes some welding, the lower shaft i welded to the corsa splined part to make removable shaft so that the rack to column shaft fits as per standard, The top shaft on the corsa is splined so i cut the part that fits to the steering and welded 924 part to it so it fitted to the corsa column as standard.

The outer column is really easy it fits over the top of the corsa part so you can still use the original upper column mounts and stalks ignition lock etc.

from under the bonnet and in the car it looks stock (apart from some extra wires and the adjuster knob for the amount of assistance)

i will do a proper write up with pics when i get time on the project 924

its made the car very easy to drive especially when it gets a bit twisty, you loose a little feel but its a lot more fun when the back steps out

Fair play. I only know hydralic systems so I'll watch andl earn...

Interesting project Steve924.

What is the view of the MOT inspectors (or whatever government entity is responsible for ensuring MV safety) regarding welded steering components?

There is absolutely no way that would be legally sanctioned down here in the penal colonies. Most likely not even in many third world countries either.

Sure there will be some interest here in photos of this conversion.

IIRC it was a fellow Englishman, BassGT, that posted of a quicker ratio pinion & rack he sourced, Quaife Eng I think. A search here will ......

Since you`re new,

its fine for the mot, the welded shafts are pinned and sleeved, the lower one that takes the strain is sleeved both inside and out and is pinned (kit cars being doing it for years) the corsa column is not modified to fit the 924. if the electrics fail it just goes back to standard steering.

the way it fits to the car you have to have a good look to notice it under the dash

the mot inspector was impressed, they checked the mounting points etc

google corsa c power steering, they have been fitted to many cars (mk1 and 2 escorts theres a mk1 golf with lots of pics)

i will try to get a picture from under the dash in the next day or so

hi pics from under the dash of epas they are not great but will get proper ones from the other 924 soon

the lower shaft is sleeved both inside and out with high tensile pins


from under the dash



the adjuster knob, it will get a scale to show level of assistance



on full it is very light, on lowest setting it is nicely weighted a bit like the hydraulic setup

cracking idea, nice to see a mad Englishman thinking outside the box,

It would be cool to do away with the potentiometer and have it automatic. Just rig some electronics to read the output of the hall effect transducer on the back of the speedo and convert the pulses to the correct resistive value. that would enable light steering at low speed (for parking), heavy at higher speeds.

It's funny you should mention the speed sensitive idea (and the mad bit), the donor car uses a converted abs signal i was thinking of sticking a abs sensor on the rear driveshaft, ive found the part number for the vauxhall signal converter (£10 ish) just a case of working out the wiring.

I think we need more nut cases in 924's , hmmm those O1E 6 speed audi 2wd gearboxes would be fun in a 924 (with more bhp of course) we just need a way of connecting the input shafts etc i might have too look into it

Just to drag this thread back from the dead since I was researching the EPAS conversion for someone else.

If you search around you'll find that the steering rack and much of the front suspension on the 924 was lifted from the MK1 Golf. The rack for the RHD 924's were similar to LHD Golfs and vise verse. The 924's are a bit of a parts bin special with a number of special parts mixed in make it interesting.

Quaife makes a faster steering gear option for the standard MK1 Golf racks. Unfortunately they don't quite drop into the 924 RHD racks, but a longer gear can be made to resolve this, more details here:

http://www.924board.org/viewtopic.php?t=30194

It seems like a standard MK1 Golf LHD rack could be swapped in to resolve the issue with the RHD 924 racks and the Quaife gear, but it might cause issues with clearances on the RHD 924's.

Those of us with LHD 924's are in good shape

Loving the updates on your 1.8T swap! Hope this helps.

Wow forgot about this thread, I will be buying the Quaife mk1 golf lhd rack and pinion at some point, I used to work opposite Quaife a few years ago lol

I think the pinion and bearing need slight modifications to fit the original housing, as for clearancing the 1.8t leaves abit more space.

The 1.8t is so much fun i've been using it as my daily for the last month, is fairly economical too even with the regular boosting
