parts used:
1992 Toyota MR2 electric power steering pump $175 Ebay
1992 Toyota Camary power steering pressure hose(needed the fitting off of it and its cheaper) $30 could have got a used one, this is new.
Stock power steering pressure hose
Custom made hose 26" total (thanks Nashville Rubber and Gasket) $45
1996 3.8 power sterring resevior, used stock large hose too(this is the one that runs to the pump) Already had this
bought 2ft power steering hose for low pressure side $4.50
75Amp SPDT relay
dash switch
80A self resetting breaker
#10 wire

If I was going to run this constantly I would put a power steering cooler on it. Also you can control it with a PWM if you didn't want it to run full power all the time. The pump has 2 main + - Wires and 4 small wires. You don't use the 4 small wires unless you wanted to control it with those wires. Mine is just using the main wires and just runs full power even when driving fast.

I got it working today. It works great for what I needed it for. I can turn it on and off with a switch. I would say it weighs slightly less than stock.
As for the reason for this. I had already done away with power steering, but still had the rack. All the pulleys were gone and I already got rid of the stock pump. Plus I had moved the radiator back and it would touch the belt now if it were put back. My grandfather bracket races with me and his shoulders have been bothering him. He needed the power steering back on it so this is what we did.

Here are some pics of the pump and wiring diagram:



Here is the bracket from the 96 3.8 power steering reservoir
I cut it off to use it to mount the pump
This is before


Here is its after cutting




Here is the left over piece, I bent it and am going to use it to mount the reservoir


Here is the pump with the hose I had made connected


Here is were I mounted the reservoir before


This part will be mounted to the body on the part that goes around the radiator. There was already a hole there anyway to put the bolt thru.


Here is the other side. This is were the bracket will mount to and then bracket to radiator support behind headlight


here is the pump mounted:


Here is the resevior mounted, I bolted the bracket to the body and it just slides on the bracket, hoses come out the bottom:

there are no adapters for toyota PS hoses? did you think of using early 4th gen PS reservoir and using the early 4th gen location behind the batt? nice write up.....as the 5th gen uses electric PS dont they.........


ps.......with a black car and a black pump its hard to make out the pics......you put it under the drivers side by where the AIR pump is/was?

I could not find the adapters. I am sure you could get the adapter if you knew the thread. I didn't and went to about 6 parts stores and no one could help me. Napa directed me to Nashville rubber and gasket. Then they told me if I had a hose from the OEM they could cut it off and weld there fitting on it. So thats what I did. It was a pian even then because at Napa they didn't want to just go get the Camry hose to see if it fit. They were trying to send me down the street somewhere else. I said "can we just try it and see" then he went and got it and it worked.

I used the 96 3.8 resevior because I had one sitting in the garage. It really doesn't matter what one you use or where you mount it as long as its above the pump. Sorry for the dark pick. I only had my cell and it was a little dark at the time. This car is my race car and has alot of parts off of it including the front bumper and frame horns. Also the fuse box is relocated to the glove box. I don't remember what was there were the resevoir is, but I know the pump is sitting where the frame horns used to be. I just lucked out and just bolted it right up using existing holes and the bracket I made. It looks factory in person.

the car is acually white. I had painted the engine bay white and I messed up and put clear POR15 on it and it turned YELLOW! So I got black POR15 and painted over it. Not what I wanted, but it was too late. Thats what you see in some of the pics, some of the parts that I have not painted black yet and they look yellow or brown.

so the reservoir is where the fuse box was.......and the pump is under that?

Whats the expected amperage draw of this pump running full steam? Just curious because of the relay you selected.

I don't know. The wiring diagram is from someone that converted a Jeep to an EV and I just went by their wiring. I think when it pulls a lot of amps is when you turn all the way to the lock. That puts a lot of pressure on it.

I guess its where the Air pump hose ran thru.

I found this pic that shows the area, this is not my car just a pic I found:

is this a good setup for a dd setup or more a track car?

I would say so as long as you have a power steering cooler. Many people do this conversion when they convert there car to an electric car, because if not they would not have power steering being they get rid of the gas engine. If you want to control it there are a couple different ways to do so. You can do a google search for "mr2 electric power steering conversion" and get lots of ideas. You could just have it shut off at a certain speed.

Nice job, I low how the engine bay is so free now of all the crap.

How does the wheel weight feel now?

Is it lighter or heavy than stock?

Its been so long since I had power steering that I don't remember really. I think you notice it most when making fast turns. It seems pretty free, but when you turn it fast you feel some resistance IIRC. I have't driven it since october so I will have to get back with you on that because I never really thought much about it at the time.
