* Engine Code: The 940 turbo uses a B230FT engine, while the 850 turbo utilizes a B5234T (for the 850 T-5R) or a B5254T (for the 850 T-5).
* Block and Head Design: The B230 and B5234/B5254 engines have different block and head designs, making them incompatible for direct swapping.
* Electronics and ECU: The engine management systems and ECU are different between the 940 and 850, further complicating a swap.
However, there are some possibilities for adaptation:
* Engine Swap with Modifications: It is possible to swap a 940 turbo engine into an 850, but it would require extensive modifications, including:
* Engine mounts: Custom mounts would need to be fabricated.
* Exhaust system: The exhaust system would need to be modified or replaced.
* Wiring harness and ECU: You would need to rewire the engine and install a compatible ECU.
* Transmission: The 940 transmission might not be directly compatible with the 850's drivetrain.
* Turbo Upgrade: If you want to increase power in your 850, you could explore upgrading the existing turbocharger or replacing it with a larger one designed for the B5234/B5254 engine.
Important Notes:
* Complexity: Swapping engines or turbocharging systems is a complex project. It requires significant mechanical knowledge and expertise.
* Cost: Consider the cost of parts, labor, and potential unforeseen issues.
* Legality: Make sure any modifications you make comply with local regulations and safety standards.
Recommendation:
If you're looking for increased power in your 850, consider upgrading the existing turbocharger or exploring a more modern turbocharger specifically designed for the B5234/B5254 engine. Swapping an engine from a different model is a much more complex and potentially expensive undertaking.
