Nissan Patrol GU ZD30 Di Turbo Upgrade | Performance Turbocharger upgrade. Drive-ability, Towing, Economy, Reliable power increase…
The ZD30 Di (Direct Injection) and the ZD30 Crd (Common Rail Diesel) have very different characteristics and tuning capabilities. Our ECP540 turbocharger is specifically engineered to increase the performance of the ZD30 Di model. It features a newly designed and engineered compressor wheel, which allows for earlier spool, matching the performance of the later ECP545 Crd Turbocharger model. It reaches a peak boost pressure of 30psi before 2300rpm, giving it a much earlier and greater band of usable torque. This enhanced performance, drive-ability and torque at any rpm, produces optimum conditions for towing.
“A must for ZD30 Di. Was thinking of selling or upgrading the engine but I’m certain now I’ve made the right choice. My ZD30 with this eclipse turbo is so smooth and feels so modern now. Thoroughly enjoy driving it and look forward to those hills.” Daniel

No exchange is required with our turbochargers, as components are custom manufactured and all 100% brand new.
Reliability
Engine reliability.
Early ZD30 Di models gained a bad reputation for engine failures (known as “grenading”). This was due to Nissan design shortcomings. To Nissan’s credit, they addressed these issues in the later DI models, and followed through to the current CRD model. We should not underestimate the ZD30 engine. The engine’s structural design is extremely robust. The reliability and functionality is no less than any other factory turbo diesel engine on the market today. Preventive measures can improve this reliability. Known issues such as EGR, fuel system quality, fuel pressure control and boost pressure stability can result in expensive engine damage.
Stable Boost Pressure.
RED LINE: This is a typical boost pressure graph for a factory ZD30 GT2052V turbocharger with a factory vacuum solenoid. This being our 2012 GU ZD30 CRD that was starting to suffer the signs of compressor surge. It is not known if this turbocharger has already been replaced before, but we do know this one is not good. From new these turbochargers can experience boost pressure fluctuations, spiking and surging and is commonly acknowledged as the weak point of these engines.
GREEN LINE: Eclipse ECP540 turbocharger with stable boost pressure.
The Eclipse Turbochargers unique turbine wheel design and function, displays stable boost characteristics and a predictable boost curve while still using the factory vacuum solenoid. Consequently due to this design feature, we have not encountered any limp criteria events whilst running our turbocharger on a standard ZD30 engine at 20psi and above using the standard ECU.
Quality Assurance
Assembly, balancing and calibration are all completed in house to ensure a very high standard of product is released. Shaft balancing and VSR balancing are to the highest standard achievable only seen in the race industry. The VNT vanes and vacuum actuator are set on our turbo test pro calibration machine and will not require any adjustment.

Turbocharger Information
Turbine Side -
A larger turbine wheel incorporating the latest in mixed flow turbine technology and volute scroll design, the ECP540 VNT turbocharger out flows the factory GT2052V by an average of 30% for a lower shaft rpm at the same turbine psi (back pressure), whilst maintaining the same drive as the smaller factory GT2052V turbocharger. This results in a gain over the factory turbocharger in low end drive enhancing low down drive-ability, but most importantly, not losing any low down drive-ability. The turbine housing is manufactured from precision cast stainless steel that will take on a gold appearance once subjected to operating thermal temperatures and is built to last.
Compressor Side -
A larger billet 6×6 custom designed and manufactured compressor wheel provides ample flow at high efficiency, well within the engine’s criteria. Its spool point is earlier than the smaller factory GT2052V turbocharger with ever increasing gains of volume and density as the boost pressure rises. The ECP540 turbocharger on a ZD30 with a ECU re-flash can comfortably run 30psi @ 20:1 afr. The intake pipe allows for a smooth transition from low pressure to high pressure at the correct velocity.
Bearing Housing -
The bearing housing used comes standard with water cooling ports.
Note: ECU re-flashes/re-maps are currently being developed for both the DI and CRD ZD30 engines, however this turbocharger has been designed to run on factory ZD30 engines for zero loss of both power and low down torque, even at very high mass flow levels resulting in very high afrs. In order to reach this turbocharger’s potential, it will require added timing and fuel via an ECU re-flash or other electronic control median.
