I recommend 2002 wrx 440cc blue top injectors. It is a direct swap and you will not need to wire in a resistor pack as you would with dsm injectors.
I still have a set of them from my 2003. Ill give them a try, looks like i will have no choice but to use an EM package. ill look around to see what the common EM setup is for a very low boosted 4g64t galant.
