* Engine Bay Dimensions: The Caravan's engine bay is designed around the 2.4L naturally aspirated engine and its associated components. The turbocharged version, even if the same displacement, is likely to be larger due to the addition of the turbocharger, intercooler, and potentially other supporting components. These may not physically fit within the Caravan's existing space.
* Mounting Points: The engine mounts and their locations are specific to each engine and chassis. The turbocharged engine's mounts won't line up with the Caravan's existing mounting points. Extensive modifications, potentially including custom fabrication, would be required.
* Exhaust System: The exhaust system for a turbocharged engine is different and likely won't fit the Caravan's existing layout.
* Wiring Harness and ECU: The wiring harness and engine control unit (ECU) are unique to each engine. Adapting these would be a significant undertaking, requiring expertise in automotive electronics and potentially custom programming.
* Transmission Compatibility: While the transmissions *might* be compatible (this would need verification), the mounting points and drive shafts would likely require modification or replacement.
In short, while a swap *might* be theoretically possible with a huge amount of custom fabrication and engineering expertise, it's not a straightforward or practical undertaking. The cost and complexity would vastly outweigh the potential benefits for most people.
