The “siamesed port problem” pops up when trying to use timed, multi-port injection on cylinder heads with siamesed intake ports (which, by definition, aren’t multi-ports).

The 907 has individual intake ports so you can use timed multi-port injection.  Later generation Lotus engines do just that. 

But all that’s academic since the Patton Machine system is a throttle body injection setup, a.k.a. an electronic carburetor style of system.  As long as the injector provides a uniform “fog” to the throat of the throttle body and the intake manifold plenum the cylinder balance should be the same as with carbs.


In addition to the return line and you might need to install a larger supply line too.  I’m not sure if the stock line can handle the higher flow. 

You’ll also need to find a place to mount the ECU, run the harnessing, install the high pressure/flow pump, etc, etc.
