Read the numbers off the injector and feed them into google, the stats should be available from there.

Had a look on here
http://protege5.ugly.net/01-14.PDF
Page 27 says that the ZS injectors flow 68-75cc in 15 secs = 272-300cc/min

Hope this helps you.

Im Pretty sure that the stock ones are around 230cc off the top of my head (its been a while so id be lying if i was 100%)

Bora and i both ended up going through Powerflow for our injectors and we had them make us both up a custom fuel rail.

we both went with 675cc injectors to start although i must admit with my 2.1L + GT3540 hungriness it wasnt enough to have a safe margin of below 80% duty cycle at about 16psi so i went to 1000cc's

but i know that the 675cc was a good middle ground tuning wise because they had good feed rating while at the same time unlike the 1000cc's they were much more tunable for a happy idle because of the lower flow (imagine tuning in percentage points with 1000cc to play with, it gets really hard on your cold start and idle maps to tune to be either not too rich or not too lean at 2-3% duty cycle)

I wish i had seen this sooner because i had a spare set of 675cc's (the ones i had replaced with bigger ones) that i just gave to the guy who bought my car as spares and i would have been happy to give them up... =(
