Turbosmart IWG75 Wastegate Actuator - Nissan Patrol TD42T, 7 PSI

The Turbosmart IWG75 is a high-performance internal wastegate actuator designed for the Nissan Patrol equipped with the TD42T 4.2-litre turbo-diesel engine. It is engineered as an upgrade to the factory actuator to improve boost control and provide smoother, more consistent power delivery.

The factory actuator can produce an inconsistent boost curve, particularly in the mid-range, which can limit engine performance. The Turbosmart IWG75 is designed to address this by providing faster boost build-up, reducing boost drop-off at higher engine speeds and maintaining more stable boost pressure throughout the rev range.

The actuator features a robust construction and is designed to replace the factory component on compatible turbocharger setups. It is particularly suitable for Nissan Patrol vehicles fitted with larger tyres, additional off-road equipment or performance modifications.
