Here's a breakdown of what's involved and the potential difficulties:
Challenges:
* Engine Compatibility: You need to find a turbocharger that's compatible with the 4D56's exhaust manifold, intake manifold, and other components.
* Exhaust Manifold: You'll likely need to modify or replace the existing exhaust manifold to accommodate the turbocharger.
* Intake Manifold: The intake manifold may need to be modified or replaced to handle the increased airflow from the turbo.
* Intercooler: You'll need to install an intercooler to cool the compressed air from the turbocharger.
* Fuel System: The fuel system needs to be upgraded to deliver more fuel to support the increased power output. This could involve modifications to the fuel pump, injectors, and fuel lines.
* Engine Management System: The engine management system needs to be recalibrated to accommodate the turbocharger and the increased airflow. This might require a standalone engine management system or tuning of the existing ECU.
* Strengthening: The engine itself may need to be strengthened to handle the increased stress from the turbocharger. This could involve upgrading connecting rods, pistons, and other components.
* Cooling: The engine will generate more heat with a turbocharger, so you may need to upgrade the cooling system.
* Safety: It's crucial to ensure all components are properly installed and the system is designed to handle the increased power and pressure.
Steps Involved:
1. Research: Thoroughly research suitable turbocharger options, compatible manifolds, intercooler systems, and fuel system upgrades.
2. Gather Parts: Acquire all the necessary components.
3. Installation: Install the turbocharger, exhaust manifold, intake manifold, intercooler, and associated components.
4. Fuel System Upgrade: Upgrade the fuel system to handle the increased fuel demands.
5. Engine Management System Tuning: Re-tune the engine management system to properly manage the engine with the turbocharger.
6. Testing and Adjustments: Test the engine and make adjustments to the tuning as needed.
Note: This project is best suited for experienced mechanics with a strong understanding of engine mechanics and turbocharger systems.
Alternative Options:
* Swap Engine: Consider swapping your existing 4D56 with a factory-turbocharged engine from another Mitsubishi model. This might be easier and more reliable than attempting a turbo conversion.
* Supercharger: A supercharger can be a simpler alternative to a turbocharger, but it might not offer as much power gain.
Ultimately, the decision of whether to turbocharge a non-turbo 4D56 is a personal one. Weigh the potential benefits and challenges carefully before embarking on this project.
