* 2.0L 4-cylinder: This was the base engine.
* 2.5L V6: This was the more powerful option.
Therefore, the engine that will "fit" depends on which engine was originally in your specific car. You should check your vehicle's documentation (owner's manual, VIN plate) to determine the original engine.
While other engines *might* be physically installable with significant modification (swapping engines is a complex undertaking requiring expertise and often custom fabrication), it's extremely unlikely you'd find a direct bolt-in replacement other than a used engine of the same type. Even then, sourcing a used engine requires caution to ensure it's in good condition.
