I'm planning on building my car into a sleeper, but I'm not sure if it is worth adding a turbo or supercharger. The car has 260,000 kms. I've also been thinking about doing an engine swap with a Veloster Turbo. I don't know much about them and compatibility with the engine. I'm not much of a gearhead, but I know enough about cars and engines to do most of it myself. The car has the 1.6L DOHC Inline 4. If I would do a different car, which one?
