The turbo PCA design is to move the SWG cannister inwards more towards the center of the turbo, thus reducing the SWG actuation rod length, and thus moving the resonance mode upwards, reducing displacement and clearing the range of engine speed excitation. To accommodate the PCA design on the engine, a new air feed pipe (or boost pipe) for the SWG cannister is required, and also a new EGR Gas pipe is required
