Dat73z Posted September 29 Share Posted September 29 (edited) Bumping the power steering thread. I'm curious if anyone has adapted the Prius EPS to the s30 chassis? It seems the Prius unit, being plug and play with it's standalone EPS ECU is desirable and easily adaptable to just about any vehicle. Also much more economical at ~$100 for a complete Prius junkyard unit versus the $1500+ for the aftermarket adaptations available today. Edit: Adding a link here for some of the known torque sensing EPS from cars found in junkyards today that could be good and economical candidates: https://www.therangerstation.com/tech/toyota-electric-power-steering-eps-conversion/ Edited September 29 by Dat73z Quote Link to comment Share on other sites More sharing options...
Dat73z Posted November 12 Share Posted November 12 Following on my previous post, I had my steering column modified by TruPig Motorsports which utilizes a Nissan Versa EPS unit. With the design of this retrofit, the EPS while large is able to just fit in with the motor and control module clocked up running a cable throttle and Vintage Air Gen II Mini HVAC unit. I think it would still be possible to fit a DBW actuator back there as well. Hope this helps someone in the future, it was impossible for me to find any information on fitting an OE EPS unit (not smaller ATV/Powersports units), DBW and AC behind the s30 dash other than people mentioning it is too tight/will not fit. 1 Quote Link to comment Share on other sites More sharing options...
madkaw Posted Saturday at 03:29 AM Share Posted Saturday at 03:29 AM I use the Truepig eps . I had to notch the angle frame that the pedals ride on just a bit off the end . Been using this unit for a couple of years Quote Link to comment Share on other sites More sharing options...

Been using this unit for a couple of years Do you experience any delay in the steering assist? A couple years ago(actually five now that I look) we had a discussion about this, and quite a few people complained that the force-sensing units had a delay and didn't self-centered very well.

Been using this unit for a couple of years Yes I also cut the notch and modified the brake pedal slightly for my preferred position + and plated in with 1/8 steel for reinforcement. I'd be curious about steering delay as @calZ mentioned. Self centering/wandering I wonder what alignment settings people were running. I've always been pushing a few degrees more positive caster since switching over to 225 (soon 245) RComps, enough where my front apron corners are trimmed a bit.

madkaw Posted Sunday at 03:28 AM Share Posted Sunday at 03:28 AM I have not noticed any delay but have noticed the lack of self centering . I’ve gotten use to it and I drive my car a lot . 1 Quote Link to comment Share on other sites More sharing options...
