Chrysler PWR steering

I'm trying to ditch the steering box and install a rack and pinion system off a Holden Commodore (Pontiac G8 equivalent) but not the current model one from around '1995'.

The factory pump that comes with this rack I'd also have to put the chrysler pulley wheel on also or get a wheel made the same diameter as the current one on it but made to the width of the Chrysler belt as the gm belt is a lot thinner.

The Chevy pump your talking about what model is it off? Is a pump just a pump or are certain pumps designed more so for steering boxes, while other pumps are only suited for racks? I figured they basically pump in high pressure one end and return via the other line so they could be used on either. Although from what yellowdart was saying pressure isn't the main issue. Mind you I am purely assuming hence the questions :-D

Had a read of that article yellowdart and was interesting. cheers

5.7 hemi said

The 5.7/6.1 pump puts out 1350 psi and WILL BLOW THE STOCK SEALS OUT OF THE STEERING BOX!!!! That is why you get the chevy style pump (950psi). Now here are the drawbacks to the chevy pump----

1. It's a chevy
2. The mounting holes don't exactly line up, so you gotta drill them out a tad
bigger to get all 3 holes to line up---not a big deal to do
3. the stock pulley on the 5.7/6.1 has to come off and be honed so it will PRESS onto the chevy pump, I recommend .002 press fit, if you don't have acess to the tools to get this done any machine shop can do it.
4. This will work for all racks and stock power steering boxes
5. Do it and have fun!!!!!
