A turbocharged internal combustion engine is provided in which the exterior of one side of the engine block has a cavity formed therein. A head is secured to the block and overlies the cylinders formed therein. The head is provided with an internal intake passageway and an internal exhaust passageway for each cylinder formed in the block. One end of each intake passageway communicates with the cavity and one end of each exhaust passageway terminates at the exterior of the head in proximity to the cavity formed in the block. A heat exchange assembly is disposed adjacent the cavity and is provided with a housing which is mounted on the block one side and in overlying relation with the cavity. The housing is provided with an inlet and an outlet spaced therefrom. A heat transfer means is disposed within the housing and is located between the inlet and outlet thereof. The housing outlet communicates with the cavity. The housing inlet, on the other hand, communicates with the charged air outlet of a turbocharger which is located adjacent the one side of the block. The turbocharger is provided with an exhaust gas intake which communicates with the exhaust passageways formed in the head. The charged air entering the housing must pass the heat transfer means within the housing before exiting to the cavity.
