Get More From Your Turbodiesel 4WD with GTurbo’s Diesel Power Packages

With turbodiesels accounting for up to 30% of all new vehicle sales in Australia, it’s understandable why so many owners are looking for ways to boost their output. That’s because the low RPMs and high compression ratios that make turbodiesel utes like the Hilux and Land Cruiser so brutishly powerful from a standing start are the same attributes that give them breathing difficulties past 3500RPM.

Big torque and low output may be the nature of the diesel beast, but that doesn’t mean they don’t deserve to breathe better. Upgrading to a bigger turbo is the tried and true option to get more air into the engine and more power out. It needs to be part of a complete package, though – one that’s guaranteed to deliver more power, reliably.

Premium Upgrade Packages For Toyota’s Toughest Turbodiesels

Let’s be honest: while there’s no shortage of turbo-diesel upgrade kits on the market for many of Toyota’s finest turbodiesels, some are inherently better than others. Reliability is just as important as output, which is why GTurbo’s high output diesel performance package lineup is the only choice for Toyota turbodiesel owners who are serious about boosting engine output without compromising their vehicle’s natural dependability.

GTurbo’s approach to building reliable power centres on engine-specific performance packages that are designed specifically for better breathing. Australia’s unique climate presents a range of engine-intake challenges that are unlike any found anywhere else on the planet, and GTurbo’s upgraded Toyota turbo packages are engineered to address them head-on on the following vehicles:

• HDJ100 and HDJ79 Land Cruisers;
• FJA300 and VDJ200 Land Cruisers;
• 70 Series and 80 Series Land Cruisers;
• N70, N80 and N90 Hiluxes; and,
• 1GD and 1KD Hiluxes and Prados.

With more than a decade of turbodiesel design, development and machining under their belt, GTurbo understands the dangers of relying on incorrectly sized compressors and incompatible compressor parts. At their most extreme, bolting on a turbo that’s too large runs the risks of overspeeding and physically breaking apart, while the excess heat produced by a turbo that’s too small can cause an engine to seize and fracture from stress. GTurbo-engineered diesel power packages may enjoy bolt-on convenience, but every component is dyno-tested and proven to handle the worst that Australia has to throw at it.

Components Designed To Take Turbodiesel Performance To the Limit

As curious as it may sound, a turbo upgrade alone doesn’t guarantee a jump in power. The quality and temperature of the air entering the turbo, the path and plumbing used by the air as it enters the engine, and even the air-to-fuel mixture are all dynamics that have to be considered. Here, however, is where the genius of each GTurbo-engineered diesel power package comes through.

Everything comes down to better breathing, and GTurbo performance packages are constructed exclusively to promote better breathing, improve intake air quality and lower intake temperatures. Every performance package is a measure of the quality of its components though, and depending on the engine and drivetrain configuration, every GTurbo package typically consists of the following:

• GTurbo high-boost turbos. Each GTurbo package contains either one or two of their upgraded titanium-billet compressors. These 100% Aussie-built units are available in either ball bearing or journal bearing configurations, and feature upgraded alloy intakes and internal reinforcements for faster spooling and a marked increase in airflow.
• A GTurbo high performance airbox. GTurbo’s TIG-welded, stainless steel airboxes are widely applauded for their solid construction, premium craftsmanship and superior airflow characteristics. Their patented double-seal lid system is the standard for aftermarket airbox integrity, ensuring a vacuum-sealed air filtration environment that is especially important for off-roaders.
• A premium GTurbo intercooler. Intercooling helps by introducing cooler, and thereby denser air mixtures into the engine. GTurbo’s large-core, combination alloy and stainless steel intercoolers are designed to cool intake air as well as assist in cooling automatic transmission fluid on select models, providing better throttle response and more consistent power delivery whenever the engine is under load.
• A GTurbo Twin Fan Kit. For performance packages that don’t include intercoolers, GTurbo twin fan kits are the optimum choice for cooling intake air temperatures. These Exhaust Gas Temperature (EGT) controlled fans are designed to flow between 1200-1400CFM each, ensuring a consistent flow of fresh air, especially when off-roading or towing heavy trailers.
• GTurbo high-flow injectors. An increase in compressor boost and airflow means nothing without an adequate supply of fuel, and that’s precisely what vehicle owners get with GTurbo’s package-supplied injectors. These injectors are engine specific and designed to match the requirements of the OE fuel system, allowing clean fuel delivery and precise atomisation, particularly at high loads.

With upgraded engine outputs capable of exceeding 340 kW and 1100 Nm is certain twin turbo/pre-DPF combinations, GTurbo diesel performance packages are the logical choice when it comes to bolt-on increases in low RPM torque and greater mid-range power output. It takes going one step even further to fully optimise the potential of these powerful, ultra-responsive packages. And fortunately, it doesn’t require going inside the engine, or breaching a vehicle’s ADR-compliance.  

ECU Tuning Makes the Diesel Power Package Difference

Because the interdependency of modern vehicles and their systems is so high, it’s important for anyone interested in boosting their vehicle’s output to consider the bigger picture of auto tuning. Factors like engine timing, the shift points on automatic transmissions and even throttle engagement points – all attributes that go beyond better breathing – also need to be looked at in order to get the most from any type of turbo upgrade. This is where the value of ECU tuning and remapping comes in.

Regardless of whether a 4×4 or 4WD spends most of its time tearing through the outback, traveling between worksites or pulling campers through the mountains, ECU tuning is the quickest and most efficient way to optimise a GTurbo turbodiesel package, offering a bevy of benefits that include:

• Even greater output and torque increases. Together with a proper ECU tune, a GTurbo power package can potentially see anywhere from an additional 40% – 100% increase in both power and torque.
• Even better fuel economy. Depending on the vehicle’s powerplant and powertrain options, a GTurbo package with an ECU tune can effectively boost fuel economy anywhere from 2% – 10% with no other modifications.
• Even greater drivability. With an ECU tune, transmission and throttle engagement points become more predictable, making it easier to put the turbodiesel upgrade to the best possible use when merging, passing or taking steep inclines.

The fact is, while everything from the scavenging capacity of the exhaust system to the delivery capacity of the fuel pump can affect performance, an ECU tune is still the best first step to reaping the benefits of a GTurbo upgrade. And once the parameters are changed, a Toyota can feel every bit as unstoppable as it already is unbreakable.

The Final Word

At the end of the day, as tempting as it to simply slap on a larger turbo and expect a double-digit increase in turbodiesel power, that’s not the best approach. Everything begins with better breathing – and if all the components needed to improve how an engine breathes aren’t in place, the results could actually be catastrophic.

A high output diesel performance package from GTurbo is the solution for all Toyota 4×4 and 4WD owners who want to get more from their turbodiesel. They’re the best power packages on the market, for the best-built utes and SUVs in the industry.
