Post subject:  Modern power steering pump?
Hello everyone,

I've been having these crazy ideas lately of doing radical "modern" things to my 225.

Today I'm wondering if anyone has ever put a modern/compact power steering pump on their engine that uses a remote fluid reservoir, as opposed to the stock 1964 integral pump and reservoir unit my car currently has.

I'm only considering this because I'm looking at possibilities to relocate my alternator and using a remote fluid reservoir would allow greater flexibility in mounting the alternator because I'm not blocking the integral reservoir access.

Thoughts? (besides I'm crazy and why am I considering this much work? :lol: )

Try electric power steering instead.

That's interesting.

There are currently two 2003 Saturn Vue vehicles in the Pick-n-Pull yard I'm going to today.

So...If I already have hydraulic power steering and did the electric conversion, do I just remove the pump and hoses and plug the ports in my hydraulic gearbox? Or do I have to source a manual steering gearbox?

It's highly doubtful you'd get the results you wanted if you didn't do a manual steering box conversion.. Steering ratios are different between the two, and as such, without the hydraulic power, hydraulic boxes are more difficult to spin. I see that the electric assist is just that, a small electric motor mounted high on the column. I can see this working, if a full conversion was done. The problem wold be adapting the modern column to the older car.
Personally, and I might be too "old school" here, but I don't trust all this electric steering, and drive-by-wire stuff quite yet.

Just why, and where are you wanting to move your alternator to?

I built a custom mount, to mount mine low on the driver's side, on that little square pad with two bolt holes. (I didn't have the factory A-100 van mounts available to me at the time.)

I'm pretty sure my friend's race car kept the power steering box and looped the hoses when he went to the electric power steering. I'll visit him and see exactly how it's put together.

Yeah, but what about the original question again, a small compact power steering pump from a modern application (OK, not electric) for use on a slant six to replace the older style pumps. Analogous to the later model starters vs the old boat anchor mopar starters....

The Saginaw pumps are highly reliable and inexpensive, especially if you already own it. If you want lighter weight on the front end of the car I'd start with the battery as the bracketry is much simpler, there is no hose adaptation, no reservoir to mount, etc.

The motivation for my original post was not about weight on the front of the car or reliability of the pump. It was about packaging or space for components in the event I need or want to relocate my alternator to the driver's side.

Plus, being a mechanical engineer and having a passion for junkyard diving, I am interested in seeing what is out there that could be adapted.

The issue(s) I see here based on what little I know about hydraulics (my primary career field is part design and fabrication, not hydraulics) is that hydraulic pumps have flow ratings and pressure ratings.

Since the power steering system is effectively a hydraulic system, I think we would need to know the GPH (Gallons Per Hour) and the system pressure (in PSI) of the factory pump and system.

This however may be difficult to determine.


Regarding the Saturn Vue electric column assist, I actually found a Saturn Vue in my local Pick-n-Pull yard and it has the Koyo electric column assist unit. and that motor is HUGE. On top of that, the more I read about adapting the system, the more uncomfortable I became with it for my car and my application.

It's interesting for sure and I admire the ingenuity of the people who have done the swap, I just don't see it as something I want to do on my car at this time.

Well I can tell you this....

My mopar steering box is very happy having its fluid moved by a Buick serpentine belt pump. The hoses even fit. ( No Slant was used in this experiment)

So I would suggest a pump and system (hoses , resevoirs , etc ) from a LT1 powered GM anything.
Remote resevoir , serpentine belt.

That's a good tip. So the GM LT1 would be found in several mid-90s (1993-1997) Chevrolet and Buick models.

Did you swap an LT1 into your car? Or did you just swap in the pump+reservoir?

Did you change the pulley on the pump away from the Serpentine?

Thank you.

My car has a L31 Vortec TBI build....but
I have owned LT1 cars.

no point in not going serpentine ....
