Camshaft Kit. Porsche 911S / 911 Carrera 2.7 ❭ CAMSHAFTKIT03
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Restore accurate valve timing and correct operation of a mechanically fuel-injected engine with this OE Match Camshaft Set of 2. Designed for compatible engines equipped with a Mechanical Fuel Injection (MFI) pump, this matched two-camshaft set provides a replacement solution for engine rebuilds, restorations and repairs where the existing camshafts are worn, damaged or unsuitable.
Fits:
Porsche 911S 1965-73
Porsche 911 Carrera 2.7L 1974-77
Camshafts are precision internal engine components that control the opening and closing of the intake and exhaust valves. Their carefully engineered lobe profiles determine valve lift, duration and timing, directly influencing cylinder filling, exhaust gas evacuation, combustion efficiency, torque and engine performance.
What This Product Does:
- Includes 2 camshafts for the compatible engine application.
- Is designed for engines equipped with a mechanical fuel injection pump.
- Controls the opening and closing of the intake and exhaust valves.
- Maintains the required valve timing relative to crankshaft position.
- Determines valve lift through the cam lobe profiles.
- Determines how long the valves remain open.
- Works with the associated rocker arms and valve-train components.
- Supports correct operation of the engine alongside the MFI system.
- Helps provide efficient cylinder filling and exhaust gas evacuation.
- Supports smooth combustion and consistent engine performance.
- Influences power delivery, torque and throttle response.
- Replaces worn, damaged or unsuitable camshafts during an engine rebuild.
Symptoms Of Wear Or Failure:
- Ticking, tapping or abnormal valve-train noises.
- Reduced engine power.
- Poor or inconsistent throttle response.
- Rough or unstable idle.Engine misfires.
- Uneven performance between cylinders.
- Difficulty maintaining correct valve clearances.
- Repeated changes in valve adjustment.
- Reduced valve lift.
- Flattened or excessively worn camshaft lobes.
- Pitting, scoring or surface damage on the cam lobes.
- Excessive wear on rocker arms or other mating components.
- Abnormal camshaft journal wear.
- Metallic particles in the engine oil or oil filter.
- Visible camshaft damage during engine disassembly.
Why Replacement Matters:
- Camshaft condition directly affects the engine's ability to breathe correctly. As cam lobes wear, their effective shape changes, potentially reducing valve lift or altering the period for which a valve remains open.
- This can restrict the intake charge entering a cylinder or interfere with the efficient evacuation of exhaust gases. The resulting symptoms may include reduced power, poor throttle response, rough running and uneven cylinder performance.
- Correct camshaft specification is especially important with Mechanical Fuel Injection. The MFI system is mechanically coordinated with engine operation, so the camshafts must be appropriate for the engine and injection configuration. Incorrect valve timing or an unsuitable camshaft profile can compromise the intended relationship between airflow and fuel delivery.
- Camshaft wear can also damage associated valve-train components. Worn or pitted cam lobes may accelerate deterioration of rocker-arm contact surfaces, while damaged mating components can rapidly wear a replacement camshaft. Metal generated by this wear can circulate through the engine oil and potentially damage other internal components.
