A turbocharger improves the performance of the engine by compressing the air in the inlet manifold, above atmospheric pressure thus pumping it into the cylinders in addition to injection of fuel in relation to the compressed air. Energy is drawn from the exhaust gas to turn a Turbine wheel located in a housing separate from the compressor which is also wheel, which through another shaft provides the needed compression to the inducted air before the mixture reaches the inlet manifold. The compressed air, subsequently, flows through intercooler, an air-to-air cooler which is located behind the front bumper with the intended aim of cooling the air to compactness and with the view of improving on efficiency of the engine. While a further pressure build up in the inlet manifold is controlled by a wastegate that opens and bypasses exhaust gas away from the turbine wheel depending on a pressure-sensing actuator and a boost pressure sensor is used to sense the turbocharging pressure. Another is the turbo shaft is lubricated by oil from the main oil gallery and floats on oil, with provision of drain pipe going to the sump. There are some specificities that must be followed because the turbo is exposed to high speeds and temperatures; do not use full throttle right after starting the car, let the car return to idle after using the gas, and let it idle for some time after using full throttle. It is recommended to change the oil and oil filter with high quality oil frequently in order to avoid building carbon on the turbo shaft and its failure.

The operation of the turbocharger is powered by exhaust gas, which flows through a specially shaped turbine housing, spinning the turbine wheel connected to a shaft that drives a compressor wheel, compressing the inducted air before it reaches the inlet manifold.

The next steps include removing the air cleaner assembly and air ducts, draining the cooling system, and removing the exhaust system front pipe/particulate filter.

Remove the air cleaner assembly, outlet air duct, and air inlet hose.
