hi ive done some searching and im getting mixed answers. My question is will 650ccinjectors be big enough without maxing them out. My build is a d16z6 75.5mm 9.0:1 cr, ported head, delta 272-2 cam, edelbrock performer x intake 68mm tb, turbo is a t3/t4 .60trim. i have a walbro 255lph pump and will be running 93 octane. my whp goal is 300-400 range will these injectors work and not overwork them getting there. im looking at the precisions i thought about getting some 750 but every set ive seen is low impedence. the 650 are the biggest ive seen still high impedence

 

forgot, will probably be running a factory fuel pressure regulator also.

 

yeah they will be plenty, 650cc will get you to 400 whp at about 85% IDC, which is good to go.

 

 

alright thanks to all for the input. wish i was rich lol im ready to drive this thing ive never had anything boosted and i cant wait. i probably like a few more months before i have everything together. and im sure ill have a few more questions too. thanks for all the help
