you cant use stock injectors when you turbo, if your looking to save some money pick up some dsm 450s and a resistor box, also your stock fuel pump are you using the one that was in your civic or one from a teg? for low boost the teg fuel pump will alright, however the stock civic pump will be to small, consider getting a walbro 255, if you plan of boosting higher, if your going to stay will low boost under 8ps i would get a walbro 190.
Also have you looked into tuning? please dont say your going to use a fmu or a hack because they will on kill your motor, your safest and most reliable bet is to get your ecu chipped and tuned using free programs like crome, uberdata or turboedit
