IWG75 Nissan TD42T Kit 7 PSI

The Turbosmart IWG75 Internal Wastegate Actuator for the Nissan TD42T 4.2L turbo diesel is engineered to correct one of the most common limitations in tuned Patrol setups — the factory turbo’s inconsistent boost control and mid-range drop-off.

In stock form, the TD42T delivers reliable durability but lacks strong, consistent boost delivery—especially once larger tyres, weight, and off-road accessories are added. This becomes even more noticeable when tuning, where the OEM actuator struggles to maintain a stable boost curve on the VNT-style turbo system.

Turbosmart developed the IWG75 to solve this by improving actuator response and control authority across the entire RPM range.

The result is faster boost build-up, reduced top-end drop-off, and a significantly more stable and predictable boost curve. This translates directly into improved mid-range torque—where diesel performance is most usable in daily driving and off-road conditions.
