Installing your turbo

Check the operation of engine to make sure it meets manufacturers specifications. Change oil, oil filter and air filter. Replace the oil supply line in all petrol/race fuel applications. Clean line in diesel applications. Do not use a thread sealer (SILICONE) on any oil line. Check oil drain for restrictions to flow such as kinked or deteriorated rubber sections and sharp bends. On fresh, remanufactured engines and heads, flush all oil passages. If applicable check intercooler or after cooler for the same. Remove and thoroughly clean intercooler. Replace the air filter element. Check for flow restrictions, both intake and exhaust, including the catalytic converter. Check for and remove all foreign objects from the intake air tract and secure all hoses. Replace the oil and oil filter. Replace any crank case breather elements. Verify the actuator C clip is secure. Verify the oil drain direction is vertical. Verify the tightness of all clamps and bolts, secure lock tabs if applicable. After installation, be sure to remove all tools from the engine compartment. Before starting the engine, disable either the fuel or ignition system to allow the engine to be cranked without starting. The engine must be cranked until normal oil pressure is developed. Once oil pressure is achieved you may start the engine. Repeat after all oil changes.
