You may put a turbo on any combustion engine - hybrid or not. But - in the CT200H its a bad idea. The petrol engine in the CT runs an Atkinson cycle. Its set up to waste much of the air drawn into the cylinder, to simulate a expansion volume larger than the inlet volume. This gives a more efficient engine - but with less horspower. This also means that the exhaust gases don't have the same amount of energy as in a traditional Otto engine - more of the energy was uset in the work cycle. So, a turbo will not have the sufficient exhaust pressure. If it did - this would help on HP but kill the emission and MPG numbers.
You may work out a suitable supercharger. This will help aspiration, but again; -kill the emission and MPG numbers.
