Anyone see this article on using the 2nd generation (2004-2009) Prius electric power steering unit?
https://www.hotrod.com/arti...yard-prius-delivers/
According to the article, the advantage is that the Prius unit has a fail safe mode that causes the unit to act as though the car is doing 43 mph, which eliminates the need for a vehicle speed sensor signal and makes it a stand-alone adaptation (once it's hooked to power sources).

I've seen that article. I'm considering using an entire Toyota steering column for mine. Just have to source one at the yard first.

Man, I would love to see that detailed and written up in the How To section!

I have thought about this a lot lately. I just helped a friend replace his EPS in his Taurus. These things are pretty simple in design, its just finding the best one to work with.

I did some research on this a couple of years ago when I did my EPS conversion. The Prius unit is a little smaller than the Vue unit I used, so it has that going for it ( especially for a manual car). The Saturn Vue conversion is well documented, and that swayed my choice. Using the threads here on PFF, I was able to install with no issues. Cost is moderate, compared to doing F-body hydraulic swap. I installed one of Bruno's variable controllers, with a three position toggle switch. Allows on the fly Low, Med, or High assist. The stock one, where you set once, would probably work OK, as I tended to leave mine on the Mid point all the time. ------------------

darbysan, did you post a thread about your installation? If not, would you share some photos of what you did?

This guy put a Nissan electric power steering unit in his '64 Falcon. He has a whole series of videos showing different EPS setups that operate in fail safe mode. Fail safe mode allows the unit to operate without having to communicate with the car's computer.
He converted his Falcon to rack and pinion and then added the EPS. In the video he demonstrates turning the steering wheel with one finger.

Thanks, darbysan. Great job on the installation and write-up.
Would you recommend adding EPS to other Fiero owners? I've never driven a Fiero so I have no frame of reference.

Would I recommend it - yes! Is it a hotly debated topic- Yes! I found the turning forces necessary to drive around town, coupled with trying to shift, etc, was too much for me. If you have larger tires, that also adds to the problem. If you have a spouse that also drives the Fiero, I think they will also appreciate the improvement.
With the adjustments available to modulate the amount of Power Steering effort available, you can adjust it to your liking. Doing the Electric PS conversion was much cheaper than the Hydraulic style of PS conversion, and does not require a re-alignment after install. It is a hassle working up under the dash, and does require some welding, but still easily doable in a weekend.
