A turbocharger pressurizes an airflow for delivery to an internal combustion engine having a cylinder block, a cylinder head, and an oil supply passage formed in at least one of the cylinder block and the cylinder head. The turbocharger includes a bearing housing having a mounting flange for direct mounting to one of the cylinder block and the cylinder head to thereby establish fluid communication with the oil supply passage. The bearing housing also includes a journal bearing, a thrust bearing assembly, and a rotating assembly. The mounting flange defines an oil feed opening configured to correspond to an oil supply passage in one of the cylinder block and the cylinder head and to direct oil to the journal bearing and the thrust bearing assembly when the mounting flange is attached to the engine. An internal combustion engine employing such a turbocharger is also disclosed.
