Great write-up hondastreet. However, you didn't have to go far for "Aspiration." Information about this conversion was available to you right here at k20.org.

Check here EHPS Conversion redone

Default Re: Electric Hydraulic Steering Pump MR2-TOYOTA 2001

Resurrecting an old thread... I am doing the MR2 steering pump conversion on my car. I am using it for a Super Stalker that we use for autoX. There is quite a bit of effort involved in turning the 10" wide tires I use.

My alternator is only good for 65 amps (battery is a small optima racing battery), probably enough for the pump. However, as a safety precaution I am thinking of using a large 2fd capacitor much the same as some people do for leveling out voltage drops in high powered car stereo systems.

Any thoughts if doing so would be of value? Would it only help with the initial surge and then only draw additional power recharging? I am trying to level out power surges from fast steering input. Thanks, Scott

Edit for above post. Does not seem to need anything to level out voltage drops! Works GREAT! Love it. AutoX next weekend. Thanks for the idea/write-up Hondastreet and F20a.org!

Were any more pics of this installation ever taken? I am about to do this installation and I am tying to figure out the best location for the pump?

Back from the dead.

I just finished installing this and it will not power on. I am using the Accord fuse box and am getting power to the 50A fuse, but the pump will not turn on.

Any ideas? I wired it up just like the pictures posted.

Hi Hondastreet,

I'm currently looking to install the same pump into my B18C'd EG, I was wondering if you had a template for the bracket you made up at all? Any help would be much appreciated.

Cheers,
Beanz

Just out of curiosity, what is the advantage of using this over using the eps from the EP3?

eps is different ehps. The older civic/integra racks are hydraulic, so you can't use eps without swapping in an entirely new steering rack and the fabrication required to make that happen. With ehps you are just replacing the pump. Ehps works well. I converted my k20 using the older mr2 pump about 6yrs ago and its still going strong.
