No, you cannot supercharge just any car. It's a complex and expensive modification that depends heavily on your engine's inherent strength, the physical space under the hood, and your budget. While a skilled shop can force a supercharger onto almost any engine, doing it improperly will lead to catastrophic engine failure. The question isn't really if it can be done, but whether it's a practical and reliable choice for your specific vehicle.
The most critical factor is your engine's internal components. Stock engines are built to handle specific power levels. Forcing a significant amount of extra air and fuel into a standard engine, especially one with high-compression pistons, can cause detonation (uncontrolled explosion of the air-fuel mixture) or simply snap connecting rods. A successful forced induction conversion often requires rebuilding the engine with forged pistons, stronger connecting rods, and lower-compression pistons to handle the increased stress.
Beyond the engine itself, you need to consider supporting modifications. The fuel system must be upgraded with higher-flow injectors and a more powerful fuel pump to deliver the necessary extra fuel. The engine's computer (ECU) must be professionally tuned to manage the new air/fuel ratio and ignition timing; an improper tune is the fastest way to destroy an engine. You also need adequate cooling, often with a larger radiator or an intercooler to cool the compressed air from the supercharger, which becomes very hot.
Finally, the cost is prohibitive. A quality supercharger kit alone can range from $5,000 to over $10,000. When you add the cost of professional installation, engine rebuilding, and all necessary supporting mods, the total can easily exceed $15,000-$20,000. For most daily drivers, this cost far exceeds the car's value. It's generally only a worthwhile endeavor for classic cars, dedicated project cars, or vehicles already known for having a robust engine platform.
| Factor | Suitable for Supercharging | Not Suitable for Supercharging |

| Internal Parts | Forged internals from factory | Cast pistons and rods |
| Engine Bay Space | Ample space for mounting | Tight, cramped engine compartment |
| ECU Tunability | Easily tunable aftermarket ECU | Proprietary, locked-down ECU |
| Project Goal | Dedicated project/weekend car | Primary daily driver |
