Bigger injectors?

[ZigsGSX97]

My question is: at what point do you upgrade injectors, and to what size? I have my car modified: k&n air filter, injen pipe, greddy type-s bov, greddy intercooler piping, iridium spark plugs, 2.5 inch exhaust system. I don't have a big turbo or intercooler. Still have my stock injectors. I have 76k miles on my ride, and i was wondering if it is worth going with bigger injectors. I plan on going with a big 16g turbo like the EVO III. What size inj.s would suffice that?

Generally speaking, upgrade injectors with turbo. 550's are just barely enough for the larger members of the 16g family, 660's would be better.

ok thanks

stock turbo = stock injectors
small 16g = 550s
big / e3 16g = 650s
bigger turbo = 720s and up

BTW, ditch those iridium plugs and get some ngk bpr7es's.
