Rick is your main man off here as he is the main mapper for project rs and crazycage, project rs was running about 250 but is now knocking on the door of 300, the cage is 350+. They both use these cars as everyday cars so they will know which ones are best for your use, im using dark green cossie injectors on mine, about 380cc i think, not really refined but the cars is not really built for comfort if you know what I mean.
