Default REplacement/Substitute for EJ20g Power Steering pump?

Victim: 99 RS w/ ej20g engine.
Got a whiny ps pump (pretty sure), and would love to know what US model car have the same pump, or can be exchanged and fit with my plumbing? I've got a few pumps lying around (i've done rebuilds on the new ones), but they're all newer style, and use the banjo fitting on the High-press line, and an external reservoir, so don't think it'll be as easy to adapt one over. I could just rebuild the one i have, but i'm not sure if its just a bad shaft bearing on the front, or if the "pump" inside has wear n tear. (its more worth rebuilding the newer ones as they usually just leak, reman's aren't avail cheaply, and rebuild parts are only $50)

So, what US subies use that pump so i can get a donor/rebuild? Or what other pump bolts right into the same spot? (looks like the bracket uses the same pattern on the block as the newer stuff, and looks like some of the RS pumps w/the round reservoir use the side-entrance, thread-in, HP line fitting.)

For reference, this is my current pump, just to be clear:

Why? They aren't any better and he'd have to buy all new lines, it's a waste of money.

Glad to see knowledgeable people chiming in, thanks guys.

So, s69subaru360, you mean anything ej from 96 or back will use this pump/res? or at may look diff, but the fitting are the same?
Its really only the high-press side that matters for fitment, as the LP sides are just flexible rubber line to the res.

I'm not totally oppossed to upgrading to the newer style, like i mentioned, i've got a low-mile, remote-res-style, RS pump lying around, and at least one newer 04+ wrx/sti style core that i just got in from a rebuild I installed a bit ago.
That seems to me to create two issues essentially:
1. Adapt the straight-in-from-the-side, thread-in fitting to a banjo fitting i can bolt on top. Can i find that fitting easily, and do i have room to do it with the hard line where it is?
2. I need a res placed over on the fender area, and mines a bit crowded with the airbox, ABS unit, and fuel-vapor-charcoal-container-thingy there. Any good ideas?

Lastly, I questioned that too: Are they any better? I mean I could simply tear mine down and get new seals pretty easily, i'd bet, as i'm fairly handy with ps pump's, but i didn't know if the older pumps had any different internals that might wear out, making it useless? I would assume the whining i'm getting is from the bearing on the shaft going bad. That's not hard to fix, but that's assuming the other internals are fairly wear-resistant like the newer pumps. (never seen bad ones, only leaky ones, really.)

So if its only a $20-30 rebuild, i'd call that the answer, but if re-man's can be had for like $50 or less, then its not worth the time.

Yeah, anything 96 and older just bolts on. They might look a little different but they work.

You can't use the remote reserviour on an older subaru with the canister under the hood, they both go in the same spot. Unless you relocate one of them and it's not worth the trouble.

Used pumps are less the $20 at the junkyards here, don't know about your area.

The older ones are actually better, it's the newer ones that fail more often.

thanks, that's good to hear. i figured at least one of the older legacy's used it. that's the case with most ej20g parts (either ej22t Leg's, or the newer 2.5GT's with the ej25d share most of our ej20g parts)

Sadly, there are virtually no Subarus in junk yards around here (and no junk yards either). One of ours has 3-4 left that are mostly stripped bare, and the other place is a suby repair/rebuilder that sometimes will sell me some stuff from their private junk pile. But i'm sure i can find on somewhere (ebay, etc)
The older pumps also seem to be avail as rebuilds for fairly cheap ($50 or less) and that's good. Its just the newer pumps that you can't get reman's easily, hence why its easier to rebuild them. Now i just need to figure out exactly which part number to buy...
