Chris Bailey Posted March 16, 2012 Share Posted March 16, 2012 Just a quick question, What has to be done to change the J-spec stock 440 injectors to bigger 550 Uk injectors? Is it just a straight swap or is it alot of work and money? Quote Link to comment Share on other sites More sharing options...
heckler Posted March 16, 2012 Share Posted March 16, 2012 theres an FAQ on here on how to do it... but if you swap to UK injectors, you will need a piggy back or stand alone ECU to control them as it will overfuel. Quote Link to comment Share on other sites More sharing options...
