my recommendations would be go with a Walbro Pump and get some 550/720 primaries and some 720/1000 secondaries. You dont wanna run the injector duty cycles high either, but you do want enough fuel, so hence bigger injectors. Also just a thought, make sure you have ALL other supporting mods. Do it right or your gonna have 2 days of fun, then a headache of a popped motor
