* Engine Bay Space: The Dakota's engine bay is designed for a much larger V6 or V8. The compact four-cylinder SRT-4 engine might *fit* with extensive modification, but it would be a very tight squeeze. You'd likely need to heavily modify or custom-fabricate the engine mounts, firewall, and potentially other body components.
* Transmission Compatibility: The SRT-4's transmission (likely a manual) isn't directly compatible with the Dakota's drivetrain. You'd need to adapt the transmission, driveshaft, and rear differential, a major undertaking requiring custom parts and expertise.
* Wiring Harness and Electronics: Integrating the SRT-4's engine management system (ECU) with the Dakota's existing electrical system would be a complex wiring project, possibly requiring a standalone engine management system.
* Cooling System: The Dakota's cooling system is not designed for the SRT-4 engine's needs. You would need to adapt or replace the radiator, hoses, and potentially the fan setup.
* Exhaust System: The Dakota's exhaust system is completely incompatible and would require a custom fabrication.
* Cost and Time: The cost of parts, labor (unless you possess extensive mechanical skills), and the sheer time investment would make this project exorbitantly expensive and time-consuming.
In short, while technically *possible* with immense effort and considerable skill in fabrication and automotive engineering, it's not a practical or cost-effective swap. It's a much more realistic and less costly to swap in a more compatible engine, such as a larger displacement four-cylinder or a V6 from another Dodge vehicle.
