electric power steering pump. I have been searching the web looking for a solution for my L83 engines lack of a power steering pump. I found a lot of compact cars have them but I am not sure they will handle the 89 silverado steering box. I found this one but man is it pricey.

Anyone have a idea of a oem pump that would work?

Ouch. I would go the salvage yard route.
Seems like Yota MR2 pumps were one of the earliest electric PS pumps and as such have been modified into all sorts of vehicles. A Google search will show you all the things they have been backfit into. But lots of car manufactures are using them now. My Kia Forte and Mazda 3 both have electric pumps.
Guess I would do an internet search on the types of new cars with electric PS pumps than see if one could be back fit.
I considered getting an electric pump just for hydraboost brakes. That would need minimal capacity.

I was going to mention the mister2 pump, but I'm not entirely sure it would last long in a heavy truck application.
TRW and Nexteer both make heavy duty electric power steering pumps, but I can only imagine what they cost.
You can look at unisteer and/or ezpowersteering, but once again, I'm not sure how well the smaller units will do in a truck.

I found a few that look promising. The only thing is I see some of the pumps use a computer to control pressure. I wonder if they can be set to run wide open or if they have to have the controller.

You could probably find a spec sheet, or even test it with a voltmeter, maybe, to find out what voltage equates to what output pressure. Then just wire it up with the proper resistors to have it always at that voltage.

electric power steering pump. Look into the Volvo V40 electric pump. They are much easier to find. It's a brushless design (more reliable than the MR2). I'm working on installing one into my LS swapped BMW.
Another option is the Subaru XT6 pump. Like the MR2 pump, they are scarce and expensive. It may not work of you do find one.
You can cruise the the electric Vehicle conversion forums and find a wealth of knowledge on this stuff.

As long as you dont need to steer fast, electric pumps usually work ok.
Some small French cars use electric, some small Mercedes cars, and the Toyotas mentioned.
But surely there is a mechanical pump you can bolt to the engine ?

I do like the toyota pump but they are hard to find in good shape as the cars are so old. This Volvo pump looks good.

Doesn't the c7 'vette have electric power steering?
The next question(s) is/are:
Is it reliable?
And is it obtainable to us mere mortals?
Because the c7 is kind of meant for quick steering, and the like.

KRC, among others, make some slick power steering pumps that mount in various locations, such as off the front of the heads.
This may be a viable option if you cannot find an electric power steering pump that fits your needs.

I wouldnt trust an electric pump on anything that needed fast steering inputs.

You miss the point, the electro-hydraulic setups simply dont have the power to respond fast enough at times.
I know several people who swapped from engine hydraulic to electro hydraulic on their race cars...for **** knows what reason. Almost all of them changed back after some time because the electric pumps simply couldnt cope.
As for the reference to the C7...I'm pretty sure it doesnt use a Volvo or any other mundane passenger car electro hydraulic setup as an afterthought
It uses a dedicated electric assisted rack designed for the job in hand, so it's a nonsense comparison.
The other option is the after fitment of electric motor assistance to the column itself that some cars use.
But again, if you want a foolproof tried and tested setup that will always have adequate assistance, just bolt a proper pump to the engine. That always works.
The other afterthoughts usually work, or work ok, but not always. Again just depends on the expectations and usage.

I think you are hanging out on the wrong site, definitely wrong forum.

By the same logic why not just stay with the stock engine?

The comparison you're trying to make is instead of fitting a good pump, you want to fit potentially a lesser quality and able pump.
So by your logic instead of the stock engine, you want a shitty 1.6 n/a diesel engine.
Just because electro hydraulic pumps are available, does not mean they are better than a mechanical pump...and in absolutely every instance I've seen where people have used them, they are less capable than the mechanical pump.
I've already stated in very clear terms the shortcomings of electro hydraulic setups. You can choose to ignore them if you choose, or maybe as stated the vehicle will never require fast steering inputs and such a setup will work fine.
And really...if you can manage an engine swap and cant manage to bolt a mechanical PAS pump to the engine...something is badly wrong. It isnt rocket science by any means and virtually any mechanical pump will be better than the electrohydraulic versions.....again, if your car is used at a level where it would even matter. Yours may well not be.
But I'd presume the forum is for upgrading performance...so do bare that in mind..
