    You remove the 2 e-torx bolts holding the fuel rail to the manifold, That is all that is needed to install 42s,

    Now what set up do you require to need 42s? Stock ecu, greenwheel(or comparble) and external IC. Or about 100 other combinations that require tuning of the a/f mixture.

    Next question, if you upgraded the valvetrain, aren't you going to install a Riva, Rotax, or Piranha ECU? Those all require 50# or higher injectors.
