Hi guys

I am in the process of installing the MR2 EHPS in my EF. I have the pump mounted, and I have a power steering rack from a EF sedan.

All of the tutorials online show 2 lines coming off the power steering rack, for integra or EK. The EF has 3 lines:
High pressure
Line to one end of cooling rad
Line to reservoir

There is another line between the reservoir and the cooling rad, meaning that two lines create a big loop. You can see it here: https://www.hondapartscheap.com/auto...ses-pipes-scat

Which of these two lines can I cap? Does it make a difference on which line is capped? I know I can use a flywheel bolt to cap one of the lines.

Here's some pics of the setup so far:

 

FYI for anyone who cares or wonders, there is a reason for 3 ports.

1. High Pressure line M14-1.5mm
2. Return line for the left side of rack M16 par 1.5mm
3. Return line for the right side of rack (I didn't measure this one, but it is either M14 or M12, same threads as a flywheel bolt from B/D series. Internet says M12-1.0mm)

I capped one line and it forced my rack to one side and wouldn't stop. You need to T the two return lines together in order for this to function normally.

 

i didnt know this was a thing (MR2 electric power steering). why do you want power steering? why electric?

 

It's electro-hydaulic, so just replacing the engine driven pump with an electrical one. Reasons I could see for using one are K-swapped track cars, packaging issues, steering quickener equipped cars, etc. Always kind of had my eye on one for future projects.
