The method for controlling valve timing for a turbo engine includes: classifying control regions depending on an engine speed and an engine load; applying a maximum duration to an intake valve and applying a long duration to an exhaust valve in a first control region; applying the maximum duration to the intake and applying the long duration to the exhaust valve in a second control region; applying the long duration to the exhaust valve and advancing an intake valve closing (IVC) timing in the third control region; applying a short duration to the exhaust valve and controlling the IVC timing in the fourth control region; controlling a wide open throttle valve (WOT) and applying the short duration to the exhaust valve in the fifth control region; controlling a WOT and controlling the IVC timing by applying the long duration to the exhaust valve in the sixth control region.
