Which is better for running a naturally aspirated motor? I understand many people install bigger injectors... but what about the intake fuel pumps? Which is a better buy? Do you have to upgrade the injectors when a person installs an intake fuel pump? Thanks for the help.

 

that question can only be answered with a knowledge of what the setup on the motor that you are reffering to is. let me know the setup including compression ratio and i will be able to answer
