Injector Sizing

Hi All,
 
Those running fuel injection on a worked 2.0l pinto, just seeing what size injectors you are running and what fuel pressure?
I am running large cam, balanced, flowed, oversize pistons, etc
 
I know i can use the online calculators which i have done, but just keen to see what others are running.
 
I am currently running 305cc but this was when i was going to go turbo. Now i am not so i am planning to go smaller. Due to the large size i am also having the run the fuel pressure down a bit which obviously isnt ideal for fuel delivery on injectors.
 
Thank you
Ionix

    305cc sounds a little large to me for an N/A 2.0 
    Are you running an AFR gauge ? 
    I expect even with low pressure its running really rich . 
    Last one i was running on a worked pinto was from memory around 220cc but could have been a little either way as was a long time ago prior to getting the turbo bug.

    Thanks Bruce
    I ended up going with 260cc Delphi injectors as that was what i worked out from one of the calculators.
     
    I am in the initial stage of retuning utilising an AFR gauage so it all seems pretty good so far. :)
