Hi,
We have an F2 engine which we use for racing in a formula style car. It has a custom fuel injection unit built for it, running an Adaptronic ECU to control it. It runs really crap. I would like to see if its possible to put a F4i fuel injected intake onto the F2 head. We could run it all through the Adaptronic, just need to know if the intake spacing and runner diameter are the same? Did the overall head of the CBR change significantly between the F2 and the F4i? Cheers guys.

 

all i know is my buddy swapped an f4i motor into his f2 haha. Do that instead, why use an old carb'd motor

 

Tight budget. If we can get an intake and make it work, its more economic than getting a F4i engine. But that being said, did the F4i fit straight in? Are the mounts in the same spot? If so, this might be a good option.

 

nah had to swap the mounts a bit but its solid. I almost picked up an f4i motor with the harness and gauges for 100 bucks
