i plan on doing the k24a1 swap and heard alot of cases where the 310cc injectors will run lean with a few mods (dh catback ect). the only thing im running is an intake, everything as far as headers and exhaust will be stock. should i be concerned about lean using 270cc? once i get enough for kpro (turbo is sitting in the garage) and a street tune whats recommended, 550cc?

I believe you want to use your stock ecu with 310cc injectors to compansate for the extra displacement. I don't think 270cc are large enough...I could be wrong. If I am, someone will correct me- I'm sure.

Just to be on the safe side, i'd go 440s

i think u can run 310cc on the stock ecu for now. i'm running the jrsc on a k20a3 and im using 310cc injectors to compensate for the extra boost. if i'm not maxing out the injectors on 8psi, i doubt you would

runing bigger injectors with an ECU that doesn't know it, is pointless

This whole post scares me...prob just typos but when it comes to your engine you have to be very precise. You should be able to run 310cc injectors on your stock ecu if you only have an intake. You will need atleast 550cc when you go turbo.
