Just like the Dodge Dart, Honda discontinued the CRZ hybrid hatchback in 2016. But this car is ripe for tuning. KBB estimates that a well-kept example from 2013 will set you back just over $9,000. With a factory HPD supercharger kit ($5,495) – which will push the output to 197 horsepower (146 kilowatts) and 176 pound-feet (238 Newton-meters) of torque – and HPD options like a rear diffuser ($400), a cat-back exhaust system ($1,400), and a sport clutch upgrade ($640), it would make an ideal Si conversion. And it won’t break the bank.
