- Incompatible mounting: The engine bay of the Mirage is designed to accommodate a four-cylinder engine. Fitting a V6 requires significant modification to the engine mounts and engine bay to ensure proper fitment.
- Drivetrain compatibility: The V6 engine generates more torque and horsepower than the original four-cylinder, requiring modifications to the transmission, driveshafts, and differential to handle the increased power. The stock transmission of a Mirage will likely not be able to withstand the additional torque and can easily get damaged.
- Electrical Issues: The wiring harness, ignition system, and fuel system of the Mirage are designed to work specifically with the four-cylinder engine. Installing a V6 would require extensive modifications to these components or complete replacements, including custom wiring and specialized sensors to ensure that the V6 engine functions correctly.
- Structural modifications: The Mirage is not designed to handle the weight and power of a V6 engine, and reinforcement to the chassis, engine bay, and suspension is necessary to maintain the vehicle's integrity and safety.
Installing a V6 in a Mirage is costly and time-consuming. It might even compromise the safety and reliability of the vehicle compared to its original specifications. It is generally recommended to stick to engine options recommended by Mitsubishi or opt for professional engine swaps with appropriate modifications.
