i'm planning on upgrading my fuel system in my 09 si. i already have the full exhaust ready to install but wanted to upgrade the fuel side. any recommendations on the fuel rail, injectors and throttle body? also, do i need to upgrade the fuel pump too or should the stock one be strong enough? i'm not planning on a major build, but planning on upgrading to mild cams in a couple of years.
