* Engine Compatibility: The engine bay dimensions and mounting points for the Rover 45 and Rover 600 are likely different. Even if the engines are physically similar in size, the mounting systems, wiring, and ancillary components may not be compatible.
* Engine Type: While both are diesel engines, the specific engine type (including displacement, horsepower, torque, and even fuel system) might be significantly different. This could lead to compatibility issues with the Rover 600's drivetrain, fuel system, and other components.
* Technical Complexity: Swapping engines is a complex procedure, even for experienced mechanics. You'd need to find a compatible engine, modify the wiring and mounting points, and potentially adapt other systems (like the exhaust, cooling, and fuel delivery).
Alternatives:
* Engine Rebuild/Overhaul: Consider rebuilding the existing engine in the Rover 600. This is a more cost-effective and less complex option if the current engine has issues.
* Engine Replacement with a Compatible Unit: Search for a used or new engine specifically designed for the Rover 600 model. This is the most reliable option, as the engine is designed to be compatible with the car's systems.
Recommendation:
It's always best to consult with a qualified mechanic before attempting a major engine swap. They can assess the feasibility and complexity of the project and advise you on the best course of action.
