I have seen Holden Astra units (TRW) fitted to many cars over here in Australia.

You can buy whole cars for $50.

I planned to use one on the power steering conversion on my 1968 Holden Monaro GTS, but it cost bugger all more to buy the serpentine kit for the SBC with the Saginaw power steering pump added.

What the heck. confuse

An electric hydraulic pump might actually make sense. Mount it anywhere, don't worry about the engine brackets and enjoy the extra HP it'll free up.

How many amps would it draw?

All I can add is that I have had electric power steering on my daily drivers since 2002 and it is great. Feel is good, feedback is good. It is basically an amplifier. I don't know the current draw but today's cars have major alternators. I have never detected a heavy load on the alternator.

Prior to that I had a car with variable-boost hydraulic power steering. That setup really messed with my head because the effort was inconsistent as it was controlled by engine RPM.

I have no issues with manual steering but it is hard to go back. The Chevelle has manual steering and it is easy. My aunt drove it for years, and my "little" wife has too!

Today's new drivers, "what's manual steering?"

Our work HHR has electric power steering and it seems to go through a lot of intermediate steering shafts. The u-joints fail. I have a theory that this is due to the fact the assist comes "above" the joint instead of below like on hydraulic power steering. There's a lot more force on the joint than on the old style systems. Or it could be GM int shafts are junk..

Todd, that is an interesting observation. But, what about the days of manual steering & a Herculean effort during parking? That input was above the joint as well. Maybe today the object is to lighten everything a little everywhere, removing mass (& strength.)

I suspect the U-joints on the old vehicles were of better quality and were a little beefier.

GM shafts are junk! biggrin My 2006 Sierra ate a couple shafts in no time, early in it's life!

With a little research, I went with an aftermarket Dorman shaft and problem solved.
