New Electric Power steering kit for the roadster- Pricing updates
UPDATE FOR THIS SPRING
As I continue to work with my EPS unit provider, we've had to make some adjustments here from the home base in California. Taxes, Liability, etc have caused us to increase the pricing on the kit to $699 Shipped Starting May 1st. SO, if you're at home during this crazy time, and are looking to add EPS, the price will remain the same $650 until May 1st. Please go to https://www.epowersteering.com/purch...factoryfivemk4 and enter the coupon code "33Machine" to receive the discount.
As always, you get a full year warranty, free shipping, and continued support for installation.
Hey gang,
I've done some engineering work and decided to offer an electric power steering kit for the small block Roadster MK3 and MK4 with small block motors. Sorry but it will not fit with the big blocks or coyotes.
What sets this unit apart from other power steering is that it's adjustable via potentiometer knob in the cockpit. You can dial up the assist for around town and autocross, or turn it completely off for the freeway and road course.
Install- It will require you to cut the current steering shaft and have the splined couplers welded on. But the welding is not a big job. Just take it to a shop. The custom bracket can be fitted and then welded, and then bolted or welded onto the frame. It will come raw so you can finish how you like after drilling or welding. Location is in front of the headers and not close to the firewall for three reasons- Heat, ease of installation, and space. I've got it installed on the 289 and it's just fantastic. I've tested with power rack from Autozone and the stock Uni-steer rack that comes with the kit. Both work great.
Pricing is $650 shipped anywhere in the US for the entire kit.
If you're thinking, "well I could go to the junkyard and get a used one much cheaper, well yes: there is always that, however like most things, getting used gear gets us on the road cheaper but we end up paying for it sooner or later. Like rear ends, transmissions, engines, .... This includes everything you need to get it right the first time!
***Currently only available for the MK3 and MK4 with small block motors.*** .

I'm about to finally hit the Go-Kart stage. Will keep your kit in mind if I'm not happy with the manual set-up.
I too have a messed up shoulder and it has finally gotten back to about 85-90%.
Also, how do you like your Gilmer Style accessory belt system?
Very nice upgrade Sir! Nice clean installation too. I think it will make it easy for a whole lot of folks to make the switch to power steering. Well done!

Gilmer works great! No problems thus far. When I researched taking my power steering rack live with the pump, belts, hoses, resevoir, etc, it was just too much. So I went e-steering.
Big Blocker. Should be no issues on the clearance. Would you consider being a beta for the 4 into 1 for me?
Yama-bro, yes, you can stretch the caster out as much as you want. I've got mine at 6 degress right now and I'm probably going to 8 or 9 degrees just to get more variance. I put about 200 miles on the car today and had a blast with it. I let a friend test drive it and he loved it vs the non power. I parallel parked like three times one armed. It's just a different car.
Although I would be honored to be your test bed for the EPAS system, I have a "custom" set of 4-into-4's (mid pipe back-to-back collectors) and V-band clamps - and - I'm a MKII with the early steering shaft coming out of the DS footbox on the engine side.
But, that being said, I am really thinking about doing some of my own R & D to see if it will fit under the dash after the pillow block but before the firewall. I'm gunna have to move a bunch of stuff to accomplish that but the effort just might be absolutely rewarding. I'm on a 18:1 Flaming River rack now so effort isn't too much of an issue with +2-1/2° caster and 275x40x17 Nitto's.
I will be following your progress though . . .

MKIV seats. FORD Royal Blue w/ Arctic White stripes.
Updates to the kit: I've decided to go with two u-joints instead of the couplers so the bracket will have more play to be mounted. What I've found is that out of four cars, each car was different in relation to the the rack input and the firewall bearing that holds the steering shaft. Being able to move the bracket with u-joints is a huge advantage. This one we put into John Tongish's track car which still had the AC bracket. It fits great.

do you think it might fit in a Mark I? I'm on my 3 or 4 power steering pump - they gradually end up buzzing over time and I suppose after some "limited" use

The unit would probably fit but I have yet to have a test mule to make the bracket for it. I need to take a look at one of my friends cars out here to see what I need to do. I'll post it up here as soon as I do.
Wow... That's bad ***. I'm getting ready to order and haven't yet, in part because I am still trying to decide on specific set up. This looks like exactly what I'm looking for, the best of both worlds. Having power when you want it and none when you don't. Did you "hide" the potentiometer knob? Do you have any pictures of where you installed it in the cockpit?
Hey Juan, I installed the knob facing down via the horizontal Break in the dash aluminum straight down from the steering column. It's barely visible behind the steering wheel. Does that make sense?
In response to Ralph's post#14, the original YouTube video was an install on a MK I, so the answer of it fitting is; yes, it will.
I am seriously working on getting this into my MK II with custom 4-into-4 headers. I'm looking into using another unit, [maybe] from a Toyota Prius (that doesn't need the controller from the EBay guy), and see if it will fit under the MK II dash (with some obvious mods to the pillow block location). If that turns out to be next-to-impossible, the Saturn unit is my next best choice.
As a side note - under the dash sounds really slick but, should it ever need servicing, I'm going to be cussing at myself for ever thinking that was a good location . . .

Has the system been installed on a COYOTE based car yet?

I was one of the beta testers for the Elec power steering and i have to say this is a really good p/s system. Once Eric got the bugs worked out by the use of two u-joints its great. Installing this was not difficult at all. What i found right off the bat was that it took away 80% of that annoying bump steer you get on the hwy. It made the cruise down the fwy must less effort and twitchy. It also made it so you can really slam it around tight corners and not wear our your forearms. And parking-well thats a no brainer!! i love it and look forward to doing the autocross coming up at qualcomm stadium.
Very interesting. So this eliminates the need for a power steering pump, belts and pulleys. Allows use of a standard 15:1 manual steering rack? Instead of an "infinitely adjustable" potentiometer, would it work with a potentiometer with detents? I like fixed positions a lot more than a more fluid knob that I'm likely to bump and lose position.
Sure does. I can look into the potentiometer for ya. in other news, based on the feedback, I'm going to change the bracket a bit so we can stick to the couplers and not use U-Joints.
On my build, I used the unisteer steering and modified the wiring to place the controller in the foot box along with the variable assist module. The motor is protected by a shield with lizard skin heat treatment toward the electric motor. I made sure I can remove the controls later. It is really tight though.

Well, we can still get you the unit and you'd just have to fab a bracket for it. Although I think I'd like someone with a few more miles on their car to be the beta.
