For the 02-05 wrx I know:
Maximum Capacity: 4.8 quarts
Minimum Capacity: 3.7 quarts (lower end of the dipstick)
I distinctly remember reading in the service manual that non turbo models are 4.2 and turbo models are 4.8
I am an anal prick about this kinda thing as I always keep the oil topped off in my engine
