Hi all, I just picked up a micro sprint car that has an F4 with carburetors on methanol. The carbs leak and need gone through as presumably years of methanol has eaten the seals. I would like to change to fuel injection as it is more easily adjusted and can save me the headaches involved with flooding a methanol engine. All of the F4I engines I see for sale are missing the injection setup, but a racing shop sells a throttle body injection kit for the F4I. My question is, will it fit my F4, and what all do I need to make it function? Thanks yall.

 

Without knowing what's in the FI kit, I would have to say probably not. The F4i head is different as well as the wiring harness, sensors, and ECU.
