FD column mount electric power steering
« on: December 12, 2020, 06:19:19 PM »
Epowersteering.com is selling a column mount electric power steering system for the FD. When I talked to him about a month ago, he said he had sold a few kits already. Since FD columns are hard to come by, he has only had one at a time and requires a core. I took advantage of his black Friday sale and ordered a system. He doesnít yet list the Fd system on his website, but can be ordered directly. I received it today, and I plan on installing it in the coming weeks after I pick up my Fd from storage.



I went manual steering several years ago and I love the feedback through the steering, but not having PS is a pain in the ass sometimes. I have a power rack and a turn one pump that Iíve never installed,  but hopefully this works out instead. The motor itself is pretty beefy and heavy so there wonít be any weight savings, but the clean engine bay and simplicity of the system will be a positive. Iíve seen that these can draw up to 60 amps at full power which is also a consideration. Iím using a self-exciting 160amp alternator which should be sufficient for all of my electrical loads.

Iíll update when I get it working.

Cool!   I have the same base hardware in my Mustang and I like it.

How does the steering feel compare to a hydraulic setup in your experience?

Looks Ike a great alternative to manual rack. Hopefully, some feel is maintained.

Hmmm Iíve looked hard into this in the past didnít know there was an FD specific kit. Roughly how much did it all cost you?

Really curious how the feel is through the electric assist.

The original controller I had used a pot to set assist.   That sucked on the road as I had to manually turn it up parking and down on the highway.  The newer controller uses torque sensing to adjust assist and actually feels good.   Iím changing to a faster rack this year which should finish dialing it in I think.

I finally got my FD out of storage and it arrived shortly before I left for a work trip. I was able to get the kit installed and working. I only moved the car around my driveway and parking in my garage, but it feels great. It is going to be a while before my car is registered and on the road where I can try it out at speed. This controller does use a knob and potentiometer to adjust assist, anywhere from zero assist all the way to being able to steer with a few fingers while stationary. Maybe a speed sensing controller will be available as an upgrade in the future.

The install was pretty straightforward. Initially I had a part that didnít fit well, so I sent an email to Ken at Epowersteering.com during the holidays. He called me shortly after and I told him about the deficiency with the kit. He asked for some measurements, and he made and sent out a new part the next morning. After getting the new part, fitment is good and the craftsmanship of the parts are good as well. Ken has been super responsive and he stands behind his product. I did send him my core, so there should be another one available for an FD.

After inquiring about it with Ken, he instructed me to order the Miata kit through the website, and to note that it was for an FD. So the pricing was the same as the Miata kit, with a good discount during Black Friday.

you think there is enough room up there for a DBW gas pedal also?      What modifications did you make to your steering rack?

I havenít seen a DBW setup in person, but the EPS system doesnít really go near the pedal. Here are some crappy pix:






I converted my rack to manual years ago by removing the internal seals, welding the quill shaft, and welding/grinding the holes. This system should work just as well on a power rack with looped lines.

I looked around their site some more and it seems that they do have a torque sensing controller add-on to replace the adjustment dial. Iím going to try it out!

This is very interesting.  I had to go back to a bigger steering wheel because my hands were hurting after 20 laps at the track with my small steering wheel and manual steering.
