It has a kamm/prius style back design, easy motor swap to a 1.5L too you'd only need the engine mounts the 1.5L sits on in a regular civic, and axles. Also think about how lightweight drives shafts, clutch, flywheel, and other usually performance oriented upgrades will help with fuel economy...less rotational mass = less work for the engine to do. Reducing friction would help to i.e. hypereutectic pistons, and ceramic sleeved cylinders, but thats out of most peoples price range.
The 84-87 or 88-91 CRX HF (high fuel efficiency) would be the best place to start. They are the lightest weight (and best MPG) of all the CRX models. It's pretty obvious the 2-dr Insight is a continuation of the CRX HF design philosophy.
