Thread: mixing/ matching power steering pump/ box brands

Tweet

With my scratch built hotrod, it will use a '94 Ranger Twin I beam front end, that does have P/S.. I could try to locate a non power box, But there rarer and it will have a BB of some sort.. How well would that box work with a Mopar or GM pump? or an older Ford pump. The Ranger pump bolts directly to the side of the engine blocks on the 2.3 as well as being a serpentine setup, and it would take a pump for an older V8 Mustang to have somthing to fabricate into.. but most any engine I will get will have PS ( being larger vehicles ). So I would just have Napa make up the correct PS lines if it would work ok

Hi Matt. I know the GM pumps have hi pressure and can blow the seals out a Ford rack and pinion. I have never tried a GM pump and a Ford power steering box though. You can bring down the pressure in the GM pump to work with the rack and pinion, I believe Heidt's has them.

I installed an Explorer power rack and pinion in my 1996 Safari van. I plumbed it with the stock GM pump. It's been in the van for a couple of years and works great. No problems. The research I did before attempting this mod revealed that all modern power steering pumps generate approx the same pressure.
