Nissan ZD30 3L

Nissan Patrol GU / Y61 2000–2016

What this engine has actually gained

One chart per version of the engine, because the same code is not the same job. The years and the vehicle it went into change what it makes standard and what there is to find. Each chart is a single vehicle: a standard run the day it arrived, and the best run after the work, in 4th gear.

80 → 112 kW at the wheels

Hover or tap the chart to read both curves at any speed.

The standard run and the tuned run are one vehicle, measured at the wheels on our own dyno, corrected to DD ATMC3 (factor 1.024), 31°C ambient, 2WD, both in 4th gear.

Best result: +31.9 kW+39.9%

This vehicle’s own before and after, whatever stage it ended up at. It is not a promise for a particular stage, and your 4WD is not this 4WD.

We have measured too few of these to publish a chart yet: 3.0L ZD30 direct injection, GU Patrol. Ask and we will tell you what we have seen on the bed.

The stages

Stage 1

adds service, intake clean and tune

from $2,570.00parts, tune and servicing, everything in Stage 1

Service, clean and tune. We service the engine properly, chemically clean the intake and EGR, then tune it to the engine as it actually is on the day: fuel, timing and boost, set on our own dyno.

Most of what you feel is low down, between 1,500 and 2,500 rpm, which is where a loaded 4WD lives on a hill or in sand.

Stage 1, 3.0L ZD30 common rail, GU Patrol

Projected from our own dyno

Road speed in km/h

Tuned, projected
Standard

80 → 94 kW at the wheels

Hover or tap the chart to read both curves at any speed.

The standard run below it is one 3.0L ZD30 common rail, GU Patrol, measured at the wheels on our own dyno, corrected to DD ATMC3 (factor 1.024), 31°C ambient, 2WD, in 4th gear.

The upper curve is 50% of what that same 4WD gained: the share a calibration carries before the exhaust and the intercooler go on. We dyno a vehicle as it arrives and again when the work is done, never once per stage, so this rung is worked out rather than measured.

Stage 2 Power

adds intake, for power

Stage 1 plus the intake.

The measured vehicle. The nearest result our dyno has measured for Stage 2 Power is the 3.0L ZD30 common rail, GU Patrol chart above.

Stage 2 Towing

would add intercooler and transmission cooler, for towing

No intercooler or transmission cooler is listed in this stage for the ZD30. Ask us. There may be another way to get there.

Stage 3

adds high-flow injectors and a bigger turbo

The point where the hardware sets the ceiling instead of the tune. High-flow injectors put in more fuel than the factory ones can pass, and a larger turbo puts in enough air to burn it cleanly rather than making smoke.

This is a fitting job with a tune around it, not a bolt-on. It wants supporting work (cooling, clutch or converter, sometimes the fuel pump) and we will say so before anything comes apart.

No curve for this rung: we have measured no Stage 3 on this engine and GTurbo publish no power figure for the hardware it takes. We will not draw one we cannot stand behind.

A build, not a package. A larger turbo again, which is where the standard bottom end, the driveline and the cooling all start needing to be part of the conversation.

No curve for this rung: we have measured no Stage 4 on this engine and GTurbo publish no power figure for the hardware it takes. We will not draw one we cannot stand behind.

Before you choose a stage

We will tell you what your build needs to stay road legal before any work starts.

GTurbo offer G260, G300, G320 for this engine, and injectors at +100%. A bigger step than the stages above is a conversation, not a checkout.

Where to next

Put your rego in the builder. It works out which of these parts fit your vehicle rather than your engine code.
Every dyno result we publish. The other engines and models, same rules.
Suspension and GVM. Power a loaded 4WD cannot put down is power you paid for twice.
Servicing and the intake clean. Stage 1 starts here, and on a high-kilometre engine it has to.
