You are talking about eliminating the gasoline engines isobaric intake expansion (throtteling).
The easyest way to do that is relocate your otto engine to the junk yard and put a turbodiesel in its place.
That would replace your isobaric expansion with double isentropic compression (through the turbo charger compressor and maybe a little isobaric heat rejection through the intercooler, then into the cylinder for compression).

On a gas engine you play a limited game mostly around the throttle plate.
On a turbodiesel the concept is simple: stuff more air into the engine all the time, get better milage and more power.
