IWG75 Wastegate Actuator Suit Nissan Patrol ZD30DDTi – 7PSI
The ZD30 3.0-litre four-cylinder turbo diesel was the most popular engine choice for Patrol buyers. However, in stock form, it tends to struggle under the Patrol’s weight – a problem exacerbated when heavy off-road equipment and larger tyres are fitted. Therefore, it’s not uncommon for owners to invest in tuning their Patrols to improve the vehicle’s performance and drivability.
One of the problems when tuning a ZD30 is the erratic boost curve afforded by the standard actuator fitted to the VNT-style turbo, preventing the engine from reaching its full potential. This is the problem Turbosmart set out to solve with the new IWG-75 internal wastegate actuator for the ZD30DDTi.
Our dyno testing showed that the standard actuator experienced a dramatic 5PSI boost drop between 1700 and 2400 RPM, which caused a corresponding reduction in power and torque. While tuning fuel and timing increased the Patrol’s peak power, it could not eradicate this drop caused by a lack of boost.
The Turbosmart IWG75 provided faster boost build-up, less drop-off at the top end, kept the boost steadier throughout the rev range – and eliminated the mid-range boost drop. The result was the higher peak power and significantly more power and torque where you need it daily – in the mid-range.
Combined with a chiptune, the results of the Turbosmart actuator were astounding. At 2000 RPM, the standard car produced 37.4kW at the wheels. With a chip alone, that was increased to 46.2kW. Adding the Turbosmart actuator, the power jumped to 63kW at the same revs – almost 60% higher than the standard.
The IWG75 Kit for the ZD30DDTi includes a Boost Reference Adapter that attaches between the vehicle’s standard MAP sensor and the top-mount intercooler, providing an accurate manifold pressure reference to the actuator without having to tap into the manifold.
If you’re tuning your Patrol, Turbosmart’s Internal Wastegate Actuator helps you fix the Patrol’s boost curve and get more power where it matters.
Includes Boost Reference Adapter with two pressure ports, two pressure nipples, a blanking plug, and fitting hardware.
CARE & MAINTENANCE
Keep your Turbosmart components working flawlessly with simple, periodic maintenance. Reliability is built in, but routine care maintains maximum performance.
- Blow-Off Valves (BOVs): To ensure a quick, clean seal, the piston and bore should be cleaned and lightly lubricated every six months.What to use: Use a soft cloth to clean and lubricate the piston with a non-viscous oil (like sewing machine oil or hydraulic oil).What NOT to use: Avoid heavy grease or thick oils, as they can slow down valve operation.
- Wastegates & Boost Controllers: Focus on system integrity. Regularly inspect all vacuum/pressure hoses and fittings for cracks, splits, or leaks, which are critical for precise boost control.
- eGates (Electronic Wastegates): Periodically apply spray grease to the butterfly valve gearbox mechanism for smooth movement.
Always check your specific product's manual for detailed steps. Simple maintenance ensures consistent boost and extends the life of your turbo system.
