Turbosmart IWG75 Actuator for Nissan Patrol TD42T 7PSI

The 4.2L TD42T turbodiesel engine was a popular option with Patrol buyers. However, in standard form, its performance leaves a lot to be desired, with the lack of power compounded when heavy off-road equipment and larger tyres are fitted. Thus, it’s common for owners to invest in optimising their Patrols to improve vehicle performance and drivability. One of the issues encountered when optimising a diesel Patrol is the erratic boost pressure curve provided by the standard VNT turbocharger actuator, preventing the engine from reaching its full potential. This is the issue Turbosmart set out to solve with the new IWG-75 Internal Wastegate Actuator for the TD42 Patrol. The Turbosmart IWG-75 provides faster boost pressure build-up, less drop-off high in the rev range, and holds pressure more steadily throughout the rev range, eliminating the mid-range pressure drop typical of the standard setup. The result was not only more peak power but significantly more power and torque where it’s most needed every day – in the mid-range. If you’re modifying your Patrol, Turbosmart’s Internal Wastegate Actuator helps correct the turbo’s pressure curve and makes more power where it really matters.
