Engine and Technical Specifications

The 1975–1989 Porsche 911 Turbo technical data section contains critical values for assembly and wear limits. Cylinder head bolt torque is specified at a multi-stage value, with final-stage angles and requirements documented in the engine data section. Coolant system capacity is not applicable as the 930 utilizes an air-cooled system with cooling coils. The engine oil volume for the 930 3.3 L is documented at 13 liters, with precise dipstick measurement required at idle. Intake valve clearance is listed at 0.10 mm in the valve drive specification table. As an air-cooled engine, the 930 lubrication system relies on a thermostat-controlled oil cooler, with maximum oil temperatures specified at 150° C.
