A full parts list would be pretty cool. Thanks for the info it’s exactly what I was hoping to see.

Thanks for the video. This will definately be going into my swaps going forward. I liked the switch panel at the end as well!

Nice. I plan on fitting one of these on my car. It'll make driving the car so much better, and less tiring.

Excellent. So much more enjoyable to drive this way. Nice work.

Thanks for adding the links and info - doing an EPAS conversion on my Camaro and was trying to figure out which motor/controller combination allows for the potentiometer dial adjustment like you have.

Great video, I'll be doing this to my 74 Corvette

I used the nissan versa motor on my mazda b2000 so I don't have the adjustable assist but my steering box got some slop so the next project is a steering rack conversion. I'm in the caribbean so our cars are rhd. The steering box is located at the front of the wheels and most cars the rack is located behind the wheels so it's not as simple as placing the rack in front the wheels, the wheels will go in the opposite direction of the steering.

as an older guy I learned that you never ever turn the steering with the car stopped. you always go e little bit, that helps to turn the steering and prolongs the steering components life. that´s valid for all kind of steering systems, even hydraulic or electric.

At some point the tyres on the epoxy floor almost sounds like the 20 century fox theme 😂😂😂😂😂. Nice video ✌✌✌✌

I'm getting ready to dump a 302 into my Datsun pickup and I need to figure out power steering. I was going to use the factory mustang pump and run it to a hardbody power steering box but it doesn't look like that factory mustang pump is going to fit. This is something I'll have to look into.

Def take this to the next level by having the switch adjustment done by the speed sensor to ecu output. I would love to see how that's done. something like 100% assist at less than 5 mph while 0% for anything beyond 5 mph.

I used to work as a steering design engineer and would NOT do this. 1 These EPS units are designed for use inside the car where it's clean and dry, with moderate temperatures. Not under the bonnet, where it may be wet or hot. Water ingress may cause corrosion on the circuit boards. 2 According to Newton, all the assist torque is reacted through that little mounting bracket. 3 The input shaft normally has an upper steering column and a bearing at the top, which eliminates bending loads. Unlike this installation, which practically guarantees them, due to cardan joint angles etc

Nice setup can u please send me the link so I can buy the sensitivity adjustability thanks man

Amazing man. I have no power steering on my 65 Mustang and it’s horrible! I wish I had the skills, tools, facilities to do this. And while I’m at it, throw in the girlfriend to test it!!!

are you going to cover the ECU wiring with water resistant material? id be afraid of it shorting if you go over a deep puddle of water or if it rains since the ECU is near the firewall where the water touches, and ive read that the electric upgrade is difficult to manually dial in at higher speeds, since the ECU, i believe, uses stock speed sensor data to adjust the sensitivity in the electric motor.. so at higher speeds, the sensitivity is decreased so that you dont oversteer at higher speeds if you have to swerve quickly iirc, like you said at the end. It'd be interesting to see or attempt a workaround around that with your ipad speedometer setup

You are right about needing water proofing. I killed a stock ECU with rain water. I don't feel the need for adjusting the power steering for my DF Goblin, but there is an aftermarket controller that has GPS speed information, and will adjust the sensitivity based on speed.

Good Install and upgrade Mate! Only thing I don't like about the unit is how big and bulky it is. I wonder if there is some factory option that is a little more discrete? I hated going to parking lots in the Z.

I actually didn’t run a fuse for the big power wire it, I suppose I could or should. I just used oversize wire and the ps motor shouldn’t pull over pull. But I guess a fuse anyway would be a nice safety. May do that later. Accessory wire is ran to a power block which is protected by a fuse.

looking like the most reasonable way to mount it without wrecking many parts. Will water touch the ECU box?

That's really cool. Now turning your steering wheel activates a snare drum 😆. You start no way to adapt a hydraulic power steering like a ZX unit to the car?

don’t think it will fit that way with my 280Z turbo engine…the turbo and exhaust is in that position = too much heat as well. I’ll see if it can be installed inside and retain the collapsible column 🤞🏻

That's really not that bad with manual steering. I had power steering go out on a 94 caprice (4200 pound car) and that was a bitch.

These 'dial up' sensitivity mods are pretty dangerous. If you have it set with heaps of assist and forget to turn it down, you could end up oversteering (and then overcorrecting) on the freeway and having an accident. The potentiometer wires are connected to a device that converts speed of the vehicle to the amount of assist, usually in the ecu. Doing this mod without replicating the speed/assist function is not safe. It can be done with a $10 arduino and a bit of playing around with some cheap components. Or you could have a 'parking assist' button that gives you 2 minutes of max before automatically falling back to a safe setting for high speed. That would be even easier and probably how I'm going to do it as I'm not going to be travelling too fast in my 68 land rover, but I don't want to be doing barrel rolls on the freeway none the less 🙃

@@acescottking I've not done it with a power steering mod as my old banger is stone age stuff. It all depends on the type of power steering you get and the type of car you have. If you can't get a signal from an ecu (mine is purely mechanical), then you need a method of calculating speed. I would use a $5 hall effect sensor module on the tail shaft and feed that into an input pin on the arduino. Then it's a bit of maths to figure out how many rpm of the tailshaft equals how many k's or m's per hour. Then use the outputs of the arduino to drive a 12v pwm module in place of the potentiometer. Then of course there is a bit of coding to figure out the output voltage curve to the rpm. But some of the power steering units I've seen won't accept an analogue signal and need a digital input from the ecu. If that's the case then you need to figure out what that signal looks like and get the arduino to replicate it based on the calculated rpm. I built a system like this years ago for a different application but using a mini plc instead of an arduino. Like I said, I probably won't do all that. I'll have a button that operates a cheap timer driven relay. The normally off contacts will allow 12v through a resistor set for high speed and the switched contacts will connect 12v through a resistor set for low speed. That way it's fail safe (switches to reduced assist in case of failure). I built one of these for an application in my garage and it cost me about $6 (and no coding!). The downside is, it's not variable and you only get good assist when you press the button. But either of these methods is infinitely safer than a potentiometer.

I think you made a mistake I think you should have put it inside the car the old Rig.

your helper looks better with her hair down.. JK nice install

God, that's awful, mounting point is horror, wiring is a mess, clearance is catastrophic. I don't see how you would to it any worse, maybe with zip ties...
