I have a 2000rs with 02-03 hubs and 4pot/2pot calipers.
I lost pressure completely for a few seconds getting off the freeway.
No leakes and and the reseviour is full. Which master cylinder to I get to upgrade the now underpowered stock unit?

Sounds more like air or water contaminants in the system, an undersized master cylinder would still stop you but with excessive pedal travel. Still trying to find a proper mc for myself.

So i've read throught this whole thread and there is not mention about number of ports. This is really important if you have 4 like me (1996 impreza L non-ABS 2.2L). I have a 15/16 (0.937 bore) and swapped my 1 pot / rear drum brakes for 2000 RS brakes. It sounds like the stock RS MS is 1". Should i go with a 1" or go to a bigger MS? What MS will bolt directly to my 4 port system? So far i can only find 2 port MS's that are bigger in bore size, which would force me to fabricate two "T" connections before bolting it up. I would rather not do that if i can avoid it.

Hopefully this will Help the Non -ABS (single stage booster) guys. I have a non abs 96 L. Upgraded to 4/2 pots, upgraded to the Japanparts non abs rear prop valve and did a direct bolt on of an svx master cylinder. The braking on the car feels awesome. To the point I don’t feel I need to upgrade to brembos. Although I’ve only been autocrossing. Here are the part numbers:
SVX master cylinder: 26410PA001
Prop valve: 034-533-27671-1 (japanparts)
