    I have an E316G i bought and will install soon as well as set of Evo 560CC injectors i will install. My car came with a FMIC, and my motor is a 6 bolt forged bottom end with Ross 9:1 pistons. I have to fix a few things but i will be running stock until i get a definite answer. But, how much boost can i run with the 560cc injectors w/ 93 octane fuel? I don't think the car came with an upgraded fuel pump. But from what i hear, i dunno if i need to upgrade rather than rewire. i'd like to run 20psi. Also, if i do need atleast a 190, do i need a FPR? i heard i do not, but i've also heard i did. thanks!

    A wideband and your injector duty cycle will let you know. Anything we say will be a guess. And we can't accurately guess due to all the variables that could make your car require more fuel than another car with the same setup.

    These are questions you need to answer for your self. Don't rush take your time till you get a logger or some sort of tuning set up. Every car is different but like stated before, you will need a wideband and a tuning device. Those items will let you know when you are out of fuel.

    Yep get a wideband and a tuning device before you go boosting away or youll be looking for a new engine.

    Like has been said before, there is no definitive answer to how much boost can i run on this setup. My advice is to get the 560's a 190 pump, rewire it along with the necessary tuning equipment then start at stockish boost levels on the 16g, i.e. 10-12 psi, and then work your way up from there until you either reach your desired boost level or until you get knock or start getting inj duty cycles above 85-90%. If you are getting knock or high duty cycles tune the boost back a bit till the knock / high duties go away.

    Why in the world would your goal be a "certain amount of boost"? What are your power goals?
