How can you possibly know you are in the high efficiency BSFC island if you don't have the BSFC of your ICE to know where that island is ???
Each ICE differs significantly.

Yup.
That's the same kind of HEV advantage for better potential P&G I mentioned previously.

Maybe.
That will depend on what the Low RPM torque output is of that other ICE you want to transplant ... not the peak best case for that ICE , but the low RPM case ... the IMA HEV system in the Insight provides a large amount of low RPM torque ... around doubling the torque from the ICE at some points.
Do you have a RPM vs torque graph for the ICE in order to compare?
