You'll need to identify the *specific* engine in each car (e.g., 4G63T, 420A, etc.) Even if the engine family is the same, you might face challenges with:
* Wiring harnesses: The connectors and wiring may differ.
* ECU (Engine Control Unit): The computer that manages the engine will be different and incompatible.
* Mounting points: While generally similar, minor differences could exist requiring modifications.
* Transmission compatibility: The transmission needs to be compatible with the engine.
In short, while parts *might* be interchangeable with modifications, a direct swap is unlikely without significant work and potentially custom fabrication. You'd need to research the precise engine codes of both cars (found on a sticker under the hood or on the engine block itself) and compare their specifications carefully. Consulting a Mitsubishi or Eagle Talon enthusiast forum is highly recommended before undertaking such a swap.
