Nope it aint gonna fit unless you do some crazy fab work. Theres another thread here where someone used an sr pump with a lil grinding here and there.

but we still have yet to find out if the 25 bracket will bolt up to the 20 since a ka dohc pump will bolt to a 25

Do you have the RB20 Pump and PS Bracket? If so why don you just use them and use a custom line. There is a write up on Racebread on how to do this. Let me know if you can't find it. I will post the link.

i have the rb20 pump but it has two pressure lines on it and one non-pressure line, i cant figure out a way to route all those lines. one pressure line goes to the rack, the rack return goes to the resivour and the resivour goes to the non-pressure line on the pump, now there is no place for the other pressure line to go off the pump, thats y i want to use the ka pump

That would be a hycus pump for rear steering. All you need to do is this its real easy. Take the pump off. Take the 4 bolts out from the back while its sitting on its face on the pulley. Remove the back section of the pump(the part with the farthest back pressure. watch were the two dowl pins were located. Then take all the fins out. Next were the banjo bolt screws in on that section of the pump you can screw that piece off the pump. I couldnt for the life of me find a bolt to plug that so.. I took it off and welded the treaded hole shut. Let it cool grinded it down. painted it black. Then I put it all back togeter. All o rings so no rtv needed. Took me about an hour and it looks oem.

To seal the other hole i got a oil pan bolt from autozone M16x 1.5. I just had to cut off the end so only the threaded part was left. I haven't hooked up the power steering yet so not sure if it's gonna seal but i imagine it will do fine. Bolt was only a couple bucks.
