so heres the deal my boy has pretty much a whole F4 (less the seat and frame) and another one of my homies has a F4i frame. so i was wondering what it would take if at all possible to convert a F4 motor to injection. does it require just swapping the throttle bodies, harness, and brain or is there more to it. having never owned an F4 i dont know that motor as well as i do and F4i. thanks in advance.

probably easy if u have all the sensors and doohickys.... same motor.... couldnt be that hard if you have all the electrical from the f4I

 

yes it takes more ,the head has a sensor and so does the crank on the right side as to tell the computer when to fire ,but it can be done.

 

cant you buy the kit to turn anything into a f4i on ebay or somthing? 19.95

 

yea dang sensors.... wait the cps is the same i belive.... i have a clutch cover from a f 4 and they both have the same sensor. i duno

 

i have two complete (blown) F4i motors, two harness', and brains sitting in my garage. so from what im getting from you is that i should have everything ???

the only thing that puzzling me is the crank censor could someone elaborate. everything else seems as if i should just be able to look at whats missing and swap it over.

yea u just need to check the sensors there should be 1 or 2 extra or so u might need to swap some **** but i could see it being done. im not sure what exact sensors the f4 came with from factory but im almost sure ur gonna have to use the f4i ignition
