Electric Power steering conversion
https://shiftsst.com/electric-power-...-corvette.html





Mounted mine on the outside of the firewall- the EAS says theirs mounts on the inside. I really don't think there is room. I spoke with a guy from EAS at IIRC Hotrod Power tour or a Summit Racing Motorama-
and he was not really knowledgeable on the C3. I have their literature and looked over the install PDF- but it doesn't show any pics of it in a C3 where the motor goes.
There's not a lot of room around the column-
And I'm a little baffled on where they are placing the motor? See pics

Here's a good read on the subject-

I also added a Flaming River Manual Rack and Pinion-
works great!!!
mine on the firewall-
I use a power steering pump from a Volvo. The Volvo pump has it's own fluid reservoir and all it needs to run is 12V battery power, a good ground and a low power 12 volt connection to an ignition or accessory wire to turn it on. Like normal power steering pumps it has a supply and return line, but unlike normal pumps it can placed anywhere.
I mounted the pump in the location where the vapor canister used to be. It's hidden away and can barely be seen from the engine bay. In the volvo, it has a two part mount with rubber isolaters. I threw away the upper part of the mount and tied the lower part of the mount to the frame.
The high pressure outlet is 16mm x 1.5, same as the return of the Borgeson., but the Volvo one is deeper.
The return line is plastic barb that fit a 3/8" hose.
The ignition signal wire that turns the unit on only draws 2.2 milliamps, so any 12V signal can drive it.
I tested the pump with a power supply instead of the battery and it only drew about 20 amps while turning the wheel in default mode. Just under 10 amps when not turning.
I got mine fro a 2006 Volvo S40 for $30 at a pick and pull. They are in 2004 - 2012 cars. I've been told that the same pump is used in C70 and many other models as well.
The Red wire goes to a fuse and directly to the battery. I use one of those separate MAXI fuse holders and a 80 amp fuse. The Black wire to a good chassis ground. The two twisted wires are not connected, they were for canbus but are not needed as this pump works fine in default mode. The small green wire goes to ignition or accessory or you can just connect it to a switch and turn the pump on manually. When the pump is turned on, there is about a 2 second delay before it starts up. The pump motor is a 3 phase brushless motor and the pump draws less current when no steering input is needed and more when turning.
I've been running this combo for thousands of miles already. It's working flawlessly.
For me the steering feel with this combo is perfect and it doesn't feel overpowered on the highway and I can easily turn the steering wheel when it's parked.
I like the concept of electric steering system. But what is the purpose of the steering wheel if you have electric steering? Why not just put a joystick at the front end of the e-brake housing (heck, make the E-brake electrically actuated, too) and dump the steering wheel altogether. That will lighten the car and make it safer!! If you went all the way with electric actuated master cylinder, you could operate the vehicle with ONLY the joystick. Either passenger could drive!
I've been amazed that some major brand hasn't done this yet...

I can just imagine driving a car with a joy stick and sneezing while holding a joy stick. That would send me into the neighboring county.

(a little too high-tech for me, though)
