I am very intrigued by that MR2 power steering unit. Very intrigued indeed. My question Spoon is why the trunk? There has to be room up front somewhere and that would really cut down on plumbing and things of course I have a battery in front so maybe electrical was a concern. I guess that by putting it in the trunk I see no reason to not try and adapt a mechanical pump to the engine instead.
Great idea however I like it a lot! Good work. |

Why did I put the pump in the back? Glad you asked.
It's in a quieter location.
It will stay clean.
When checking engine fluids, its right there with the rest of the needy.
Notice those 3 clips with all those wires? All my electrical connections are in the engine compartment including relays.
I felt it was a lot easier to run 2 hoses to the front than all those wires to the rear.
Another reason for in the back.. Since the pump is hot with key on, I didn't want it to be running unless the engine was running. So I added an adjustable pressure switch and tee'd into the oil pressure sender. So it only runs when there is oil pressure.
Wait there's more !!.. If I ever swap in a LS6 engine all I have to do is connect the hoses to the pump.
By the way those pumps are selling on ebay for around 300 bucks and up. Some without the clips.
Think I paid around 275 before they started getting hot.
Another issue is the Fluid. The fluid designed for this pump is very expensive at $45 a liter and it took 1-1/2 liters to fill the system, hoses rack and all.
Most Toyoto dealers never even heard of it. I had them order it for me. Better than risking a $300 pump.
I'll gladly answer any questions.
