Factors to Consider:
* Engine Compatibility: The 2.7L and 3.5L engines might have different mounting points, bell housing patterns, and other physical dimensions. You'll need to determine if they are compatible or if you'll need adapter plates or other modifications.
* Transmission Compatibility: Make sure the 3.5L engine is compatible with your existing transmission. The bolt pattern and output shaft size might be different.
* Electrical Systems: The engine control units (ECUs) and wiring harnesses might need to be swapped or modified to work with the new engine.
* Exhaust System: The exhaust manifolds and piping might need to be modified or replaced to fit the new engine.
* Cooling System: The radiator, hoses, and water pump might need to be modified or replaced to accommodate the 3.5L engine.
* Fuel System: The fuel injectors, fuel pump, and fuel lines might need to be changed or adjusted.
* Accessory Drive Belts: The alternator, power steering pump, and other accessories might need new belts.
Challenges:
* Space and Access: Working on the engine bay can be tight, and you might need to remove other components to make room.
* Cost: This project can be expensive, especially if you need to purchase new parts or hire a mechanic.
* Expertise: Swapping engines requires a significant amount of mechanical knowledge and skill.
Recommendations:
* Research Thoroughly: Before attempting a swap, do your research and consult with experienced mechanics or engine swap specialists.
* Consult a Mechanic: It's highly recommended to get professional help for this project. A skilled mechanic can assess the compatibility, identify potential issues, and guide you through the process.
* Consider Alternatives: If you're looking for more power, consider other options like supercharging or turbocharging your existing engine.
Conclusion:
Swapping a Chrysler 2.7L engine with a 3.5L engine is a feasible but complex project. Thorough research, professional consultation, and a good understanding of mechanical systems are crucial for success.
