    Stock H22A and F22Ax injectors

    What is the stock cc on the injectors of these motors? Thinking about an upgrade to my injectors and fuel rail. Any suggestions?

    TIA

    Happy

      unless you have any major upgrades such as a turbo/supercharger, there's really no need to upgrade your injectors. As for your fuel rail, the oem fuel rail can support up to 650+ hp. One of the last things you need to worry about. You would also need to retune your car to compensate for the extra fuel the injectors are dumping or you would just flood your motor.

        Exactly. "upgrading" your injectors won't add any power. It will probably result in a loss of power, honestly.

        This is the 4th thread I've seen like this in the past few weeks... why is everyone so interested in bigger injectors these days?




        I wish people would understand WHY they're doing something, rather than just slapping parts on their cars with no good reason. Between injector "upgrades", ignition upgrades, and worthless headers... the money spent on this trash could be used for REAL upgrades!

          Because all high Hp cars have big injectors - it must make more power by having them.
          Lack of understanding is just the start. No-one researches anymore, to find out whats good and whats not.
          It just goes along with the - Someones mates, brothers, cousin fitted a new airfilter to his stock D16 Civic and hes got like 500hp now.

          Someone says it - Someone else believes it, Its exactly the same way scams work.


          If the OP has supporting mods to suit the need for bigger injectors then the answers are above, but keep in mind it will still require tuning.

          If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

            Because more air means more power. Thats why we upgrade our intake manifold. Thats why people think more fuel will help too.

              I asked because I was curious as well and I just didn't know. I figured that going up to 450cc at most but thank you guys you answered my question. So that answers my questions
