A 2004 Chevy Cavalier can be turbocharged by purchasing a turbo kit including a turbo, wastegate, fuel injectors, manifold, intercooler, clutch, and exhaust. The stock engine is removed and inspected for wear before swapping in the new components like the clutch, manifold, and injectors. Finally, the car is tuned at a performance shop and can be enjoyed with over $4,500 invested to add power.
