STAGE 4 | 240KW

HILUX 2006-2015 D-4D 3.0L | STAGE 4 | 240KW

The Hilux D-4D 3.0L Stage 4 upgrade is the ultimate Hilux 3.0L upgrade.

The upgrade package starts with our trained technician fitting a new G-Turbo KD-250 Grunter Stage 2 turbocharger to the engine as one of the limiting factors when upgrading the 3.0L engine is the size of the standard turbocharger which dictates the peak power and torque the engine is capable of.

The G-Turbo turbocharger targets great low down response and the ability to carry the performance/boost efficiently throughout the rev range. The Grunter turbo has a high response turbine wheel, larger and more efficient compressor wheel, upgraded thrust bearings, 30% stronger main shaft and a higher flow VNT system. Its designed boost is 26psi and can be operated efficiently from 10-32psi max.

This all adds up to a super efficient, more responsive and ultimately more reliable turbo capable of flowing well over 20% more air with zero downsides. The G-Turbo turbocharger is also based of the factory turbo so it’s a direct fit and requires no other modifications to install.

The sizing and location of the standard intercooler are not suited for sustained hard driving, 4 wheel driving or towing. As such, we recommend replacing the top mounted intercooler with something more designed for higher performance. The Process West front mount intercooler features a heavy duty design and its much larger capacity and ideal location is much more able to control the heat generated when towing or off-roading and the silicone intercooler hoses are significantly stronger than the factory rubber hoses thus maintaining the engines power and reliability in all situations. We consider the intercooler as almost a mandatory requirement with the turbocharger upgrade as we have seen a 40 degree drop in intake temperatures after installation.

We continue by fitting new +30% fuel injector caps to increase fuel injector capacity. A Pacemaker 3" turbo back exhaust system is fitted to improve the engine's breathing and we complete the mechanical upgrades by fitting a Process West SEPR8R air oil separator to capture oil mist before it enters your engine's intake which can lead to a carbon build up in your engine's inlet manifold.

We complete the package by custom tuning your vehicle's ECU on the dyno in real time utilizing the latest ECU tuning software to maximize power, torque and fuel efficiency and testing your vehicle on the road to make final adjustments, optimizing your vehicle's performance and driveability. At the end of this upgrade we will provide you with a dyno graph comparing the before and after power & torque increase the upgrade has made to your vehicle.

Key Features

The Stage 4 package addresses the next level of components that limit power; generally this will be a turbocharger and associated hardware upgrade. The turbocharger upgrade is aimed at increasing air flow into the engine; this allows extra fuel to be added for more power and torque throughout the rev range. We still maintain our ‘reliability first protocol’ which maintains safe air fuel ratios and low EGT’s. You will note that the Stage 4 package may not include what is traditionally thought to be ‘essential diesel upgrades’ but rest assured, if it’s needed, it will be in the Stage 4 package.

Notes

• Important - Manual transmission vehicles will require a clutch upgrade to handle the additional torque.
  
• Power figures listed are estimated kilowatts at the flywheel based on results typically obtained by HPF on HPF’s dynos and are based on a automatic vehicle with standard driveline and standard wheels and tyres. Actual power can vary based on each specific vehicle.
• We advise against increasing the power output substantially on high kilometer engines, if your engine has in excessive of 150,000kms please contact us to discuss options.
• Whilst every attempt is made to ensure prices listed online are correct, they are subject to change at any time.
• Additional parts may be required in some cases depending on the condition of the vehicle. Cost of these parts and additional labor required may incur additional cost.
• Images are for illustration purposes only.
