2jz swapping my clean kouki after 16 years

[silviaks2nr]

stock s14 column


stock s14 and equinox columns stripped down


s14 column and shaft


These are the important parts needed from the GM eps for the conversion.
red arrow- splined/female splined upper steering shaft will be welded to the upper part of the s14 steering shaft
yellow- section of the 3 bolt flanged tube that bolts to the motor will be welded to the upper part of the s14 steering column
green- output shaft from the electric motor and corresponding splined u joint needs to be welded onto lower s14 steering shaft before the firewall


you need to cut the female splined portion down below the flared area so it fits inside the steering column


welding/sleeving the female splined shaft to s14 upper steering shaft





upper column completed



U joint that connects to the output shaft of the motor welded to lower section of the s14 steering shaft


completed EPS s14 column vs stock




You need to heat the duct work here and slightly deform it to make room for the electric motor


installed



Here is the controller I used. Super easy to do.

and where I mounted the potentiometer. You can also see where the lower cover had to be trimmed some to clear the electric motor.

I found a couple of videos of this conversion other enthusiasts did. I think this guy gave a good explanation of this conversion.

I'm glad to see people continuing to innovate. looks like you can relocate the steering ecu if you desire. But seems you made it work in the oem location so that's cool.

Haven't watched those videos but I agree it's definitely a nice upgrade. Lots of people are doing it in muscle cars too. I had been told that you can move the ECU as well but I attempted to do it to another GM column at the pull yard just to see and when I pulled it off there were several small wires that had to be extended and one of them even tore out of the solder joint. Perhaps it can only be moved on some and not others? I decided not to try to move it for that reason. The trimming to that lower panel was really minimal and you have to crouch down to even see the electric motor in there so no big deal to have to trim it IMO.
