2. Intercooler: The intercooler cools the compressed air from the turbocharger before it enters the engine. This is important because cooler air is denser, and therefore contains more oxygen, which can help improve engine performance.
3. Intake Manifold: The intake manifold is connected to the turbocharger, and it's responsible for distributing the compressed air from the turbocharger to the engine's cylinders.
4. Downpipe: The downpipe connects the turbocharger to the exhaust system.
5. Wastegate: The wastegate helps control the amount of boost pressure the turbocharger produces.
6. Blow-Off Valve (BOV): The BOV releases excess boost pressure when the throttle is closed.
7. Boost Gauge: A boost gauge can help monitor the turbocharger's performance.
8. Fuel Injectors: If you increase the amount of air to the engine without adding more fuel, your engine will run lean and potentially damage the engine. So, an additional set of fuel injectors may be necessary.
9. Engine Management System (EMS): An EMS is used to adjust the engine's fuel injection, ignition timing, and other parameters to ensure that the engine runs properly with the turbocharger installed.
10. Additional Cooling System: A turbocharger can generate a lot of heat, so an improved cooling system may be needed.
Please note that this is a basic list, and additional parts may be needed depending on the specific vehicle and turbocharger system being installed. You will need to consult with a professional to obtain accurate information for your specific vehicle.
