Which inlet do you plan to use? Blowzilla for Flowzilla?
If you're planning to on the Flowzilla then bite the bullet and swap over to mass air and 42lb injectors. Your mass air sensor housing should be at least 80mm. Your throttle body should be at least 75mm.
I recommend a Pro-M for the meter and Accufab for the throttle body.
Of course, all this means that you're going to require a custom dyno tune to get it all to work together. You're also going to need a 255Lph in-tank fuel pump. Your existing fuel rails will work just fine.
