Adding power steering to an r4 questions

Recommended Posts

I have a 2004 R4 that has armstrong steering and I would like to add Power steering to it, if its not to difficult. Grand kids cant drive it, is that a good thing?, nah.

Any help would be appreciated.

It’s relatively simple…but I don’t know if I’d make it too comfy for the grandkids

You can use an electric column out of a 2009 Nissan Versa (or other cars COROLLA, Prius, Kia, cube, Yaris)…easy to find a remove in the junkyard, don’t even have to get under the car! Get the whole thing including the steering wheel and ECU (computer).
I had to weld on a piece of angle iron to get it mounted, but the steering shaft actually fit perfectly onto my 2009 T4 rack.
Connect + and - to the winch battery connections and the third wire to a switched 12v source, and you can turn that beast with one finger.
Cost me $125 and I have been wheeling the Tennessee rocks and mud for years on 30” tires without any issues!
I’ve got a post on here somewhere about it…Joyner trooper power steering.

Thanks mixfixdave!!!  Is the ecu for the whole car? or just for the steering?

We have 12 grandkids with #13 on the way.  Gotta keep em busy.

I' not familiar with new cars, AT ALL, they dont need a pump and rack?

Thanks for the help!

The ECU is just for the power steering…controls the electric motor/assist that is built into the column. Just follow the short wiring harness.
You keep your rack and maybe some of the original shaft (I did), the EPS just gives you some assist.
It’s also a great upgrade for an old muscle car because no hydraulics are necessary.

      Thought I’d post this in the general forum to try and get some more ideas.

      Starts and idles fine, drives well until you actually try to go, then starts to sputter as if it’s starving for fuel. Does this no matter what fuel pressure I set it too. I’ve tried 35-80psi

      Not sure if this has been discussed before but here it goes; 
      If i lower a utv and put some more grippy/less of roading tires, can it handle like a go kart? Especially the 4-seater ones?

      I have a joyner trooper think 2007 model 1100cc and it will turn over but not getting any fire. Put new coil on it new crank sensor and when I check the plug going to my coil pack with test light it shows that it don't Have power and seems to be saying there's no ground either. Mine has 3 wires black,white,and orange

      I think my stator (alternator) may be giving up on me... Barely maintaining a constant 12.5 volts.. Checked all connections. No corrosion or melted spots.. I unplugged the leads that come from the Stator at the engine, both are only putting out around 12 to 13 Volts V A/C.... Whereas it should be 24VAC+ at idle.
      Manual calls for .2 to .4 ΩOhms maximum across the leads, My meter was showing .7Ω..
      EDIT 8:00PM
      I scraped off a bit of the insulation behind the stator wire plugs to rule out a bad connector (not likely, being both of them) and from the copper wires to ground, still only 12 volts AC or so... Can't complain,  it did it's job for 20 years.

      I've always adjusted small engine idles by ear.....  but i finally decided to buy a tachometer... it came in the mail today so i tried it out on the mule. it's the kind that wraps around the plug wire.
      fire the mule up, the idle RPM spec in the manual  is 1,300...  and the way i have it adjusted now it was idling at 1,260, let it warm up and bumped it up to 1300, which wasn't much
