Converting 2004 Boxster Power Steering to 12V

Thanks John.

Radium king,

I have everything I need except for the fittings on the rack side. I will check out go spec racing. BTW, is that same as GSR racing?

Go spec auto racing --> GSR --> Trinity Auto sport don't work on Porsche's now so they cannot help. I will have to figure some ways of using the existing Porsche line, cut it and have a shop crimp a 6AN line on it...

Just looking into this, what year pump are you sourcing??

thanks.

p.s. are you re-using the mounting bracket, upper resivior, is wiring an issue (i.e. do you need the controller module?), did you resue the oem fittings on the pump?

thx

Hi Matt,

I got the PS pump from 2001 MR2 Spyder. I am fabricating the mounting bracker myself, as you saw yesterday...:-). The pump has its own reservoir and I don't think I need another one. There are good articles on the wiring, in fact there is a sticky article. The controller is part of the pump assy. I got the fittings and high pressure hose from Summit racing. Mostly I am using Fragola fittings and hoses. I am getting the rack end fitting from Woody and will see if I can get 6AN tips welded to the ends. Will post pictures on my website's Power Steering section once done. You can check it out here:

Update: Was able to source the parts and fittings needed and am almost done with the PS setup. Still need to finish up the lines and connection on the rack side...

Some pics attached of the progress so far for those who are interested. If you want to see more pics check out the Power Steering Pump section on my build website (WIP)... boxsterev

Thanks to all for their responses and help.

Have a question for those who may have dis-assembled the PS lines on the rack side in the Boxster.

See attached pic. One of my options is to have someone TIG weld the fitting on the High pressure side line on the rack side. Can do the same on the Low pressure side if I want. (Interesting info is that the metal tube on high pressure side is steel and the LP side is AL).

Question: Other than the O-ring on the fitting that goes into the rack (that can be seen in the pic), is there another O-ring inside the assembly that allows the metal tube to swivel in the fitting? If there is, the heat from the welding may destroy that o-ring. I would then have to go another route and avoid welding. Also need to think of the heat will destroy the one-way valve on the HP side fitting...

Need to know if there is an o-ring inside the fittings at the place marked by arrows. Appreciate if anyone knows...

PorscheFan,

No, there are not any O-rings where your arrows are pointing, actually the thin aluminum tubes are press fitted into the connector and this is a weak point…

On my car, this is the place were started leaking, and what I ended doing, was to weld (ok, took it to someone that knew how..) an AN fitting directly to the coupling that attaches into the rack.

Basically the same idea you have but eliminating the thin 90 degree aluminum tube and used new O-rings on the fitting that goes into the rack.

On my car, I used the return (low pressure side) of the rack to connect an Setrag (..?) oil cooler and after 4 or 5 years I have not got any more leaks or fried PS pumps…

Good luck!
