DIY electric power steering

[ablake211]

I am trying to decide what the best route is for my turbo build. Hmmm

Someone get danzan in here. I want answers!

Good luck getting Dan, he sold his car a year ago.

 I have been on the street with my LS6 FD with a power rack, a looped hose and no power assist since 2004. I dont miss the the power steering, the only time its a little difficult to steer is when the car is at a stand still. Give it a shot without power assist, the less wieght you put up front the better off you are.

One of my friends uses a Vauxhall power steering column in his Evo.  It must be the same as the Cobalt column.  Unfortunately I don't have any other info to offer.  But there are standalone controllers on ebay UK.

Bumping a old thread but there is good info here.

I don't know if someone knows or can confirm that but the 91-99 MR2 has a remote oil reservoir and a adjustable pressure screw compare to the 00 + MR2 Spyder one has a oil reservoir on the pump and the pressure isn't adjustable unless you connect to a VSS.

Which pump should we use ?

Do we need to install a oil cooler or it can be run direct ?

I'm starting to gather parts to convert my LT1 FC to electric power steering next winter so I have all summer to find what I need but sometime it is the time you need to find the right parts at the right price.

^^^  You want the SW20 (91-99) pump.  It does indeed have a 1/2" or 5/8" (I believe 5/8") inlet on the top/side from an external reservoir and a pressure adjustment screw.

I would suggest running a small -6an cooler on the return if you're roadracing/drifting/autox, but for normal spirited driving and light track work it'll be fine.

Make sure you're wiring it up with 8ga wire or thicker and a 50A or 60A fuse & breaker.  I've got 3 or 4 cars using them this year and they peg 50A just firing up at no load, and 60A+ when you're really working it.

Perfect thanks.
I don't do auto cross or road racing.
This is for a sunny day car so I should be fine.
Thanks.

I am still planning to do this as well.

June 2011.

I'm slowly gathering parts for my MR2 electric Power Steering conversion.

So far I have the original Power Steering rack that was on my Turbo II ( Thanks to Rob XX 7 for that )  and I have received my 91-95 MR2 electric Power Steering pump.







Now I have many questions.
There is like 7 holes on the power steering rack but I have no idea which one does what ..... 


I put numbers on every holes and I would like someone to tell me what they do please .




Numbers are small but it is 1 , 2 & 3 :









...4 & 5 here :










...6 , 7 here :









and the pump 8 & 9 :







Talking about this pump , how is it suppose to be mounted ?
Where is the top  ?
Thanks.

You can mount the pump anyway, anywhere,  that allows convenient access for getting to the adjustment screw & simplifies the routing of the pressure, return & remote reservoir hoses

[mpcv2000]

You're back , cool.

4 and 5 go to 6 and 7 via the factory hardlines, but I don't recall the order.  The FC service manual will have that for you.

8 on the pump is the high pressure outlet, 9 is the reservoir inlet.  Mounting is flexible, most people mount so that they can get to the ports and the adjustment set screw on the pump.

I'm sure you will, but get new steering rack bushings.
