Can you swap a 2002 2.7 Intrepid engine for 3.8 from 2007 Chrysler Town and Country mini van?

It is possible to swap a 2002 2.7L engine from a Chrysler Intrepid with a 3.8L engine from a 2007 Chrysler Town and Country minivan, but it would require a significant amount of modifications and custom work. Here is an overview of the process and the challenges involved:

1. Engine and Transmission: The 3.8L engine from the Town and Country is larger and more powerful than the 2.7L engine in the Intrepid. This means that the engine mounts, transmission, and other components would need to be modified or replaced to accommodate the larger engine and its different dimensions and specifications.

2. Engine Management System: The 2002 Intrepid uses a different engine control unit (ECU) and wiring harness than the 2007 Town and Country. The ECU would need to be reprogrammed or replaced to work with the 3.8L engine, and the wiring harness would need to be modified or replaced to match the different electrical requirements of the new engine.

3. Exhaust System: The exhaust system of the Intrepid would need to be modified or replaced to accommodate the larger displacement and different exhaust manifold of the 3.8L engine.

4. Fuel System: The fuel system of the Intrepid, including the fuel lines, injectors, and fuel pump, would need to be modified or replaced to supply the increased fuel requirements of the 3.8L engine.

5. Cooling System: The cooling system of the Intrepid, including the radiator, hoses, and water pump, would need to be modified or replaced to accommodate the increased cooling demands of the 3.8L engine.

6. Driveline: The driveshaft and differential of the Intrepid would need to be modified or replaced to handle the increased torque output of the 3.8L engine.

In addition to these technical challenges, there may be legal and safety considerations associated with performing such a significant engine swap. The modified vehicle may not meet the safety and emissions standards of your jurisdiction, and you may need to obtain special permits or certifications to operate it legally.

Overall, an engine swap of this nature is complex and time-consuming, and it requires specialized knowledge and equipment to execute it properly. It is generally recommended to consult with experienced mechanics or automotive professionals to assess the feasibility and potential costs involved in such a project before attempting it.
