Upgrade your M52B28 Engine with Cat Cams, a leader in the performance-aftermarket camshaft industry. These Camshafts will increase airflow into the engine by increasing the overall lift and duration over the factory cams. With their Sport cam setup, you can run all factory valvetrain, with no valve spring upgrades necessary! The VANOS (VVT) system on the intake camshaft changes the valve timing: M52 /B28: from 115° to 90° (exhaust: 105° fix) The data are shown for full intake retard (disengaged VVT). Check the distance between valves and piston to be 1mm at least with VVT engaged. Wrong installation will cause severe engine damage! Duration Intake @ .1mm: 257° Exhaust @ .1mm: 257° Intake @ 1mm: 220° Exhaust @ 1mm: 220° Lift Intake: 10.15mm Exhaust: 10.15mm Lobe Angle Intake: 110° Exhaust: 105°
