- Engine: This is the main component and includes various internal components such as pistons, cylinders, crankshaft, camshaft, valves, and oil pump.
- Engine mounts: These components attach the engine to the vehicle's frame or subframe.
- Transmission: The transmission connects the engine to the drivetrain and transfers power to the wheels. In some cases, the new engine may require a different transmission or an adapter plate to connect to the existing transmission.
- Driveshaft: The driveshaft connects the transmission to the rear differential or transaxle.
- Exhaust system: The exhaust system consists of components such as exhaust manifolds, catalytic converter, muffler, and tailpipe. The new engine may require modifications or a custom exhaust system.
- Cooling system: The cooling system includes components such as a radiator, water pump, thermostat, and hoses. Depending on the engine and vehicle compatibility, some components may need to be modified or replaced.
- Fuel system: The fuel system includes components such as fuel tank, fuel lines, fuel pump, fuel injectors, and fuel pressure regulator. Modifications may be required to ensure compatibility with the new engine.
- Electrical system: The electrical system consists of components such as starter, alternator, battery, wiring harness, and engine control unit (ECU). Depending on the engine and vehicle compatibility, some modifications or reprogramming of the ECU may be necessary.
- Engine accessories: These may include components such as power steering pump, air conditioning compressor, alternator, and coolant reservoir. Some of these components may need to be swapped or modified to fit the new engine.
- Engine management system (EMS): This system includes the engine control unit (ECU), sensors, and actuators that monitor and control various engine parameters such as fuel injection, ignition timing, and emissions control. It may need to be swapped or reprogrammed to match the new engine's specifications.
It's important to note that this list is not exhaustive, and there may be additional parts needed or modifications required depending on the specific circumstances of the engine swap. Consulting with a qualified mechanic or automotive specialist who has experience in engine swaps can help ensure that all the necessary parts and components are identified and obtained.
