• Poor fuel economy and reduced range per tank
• Sluggish acceleration, especially when loaded or towing
• The engine is struggling on hills or highway inclines 
• Lack of power for commercial or passenger transport needs

Why Upgrade Your 3L Engine with Turbocharging

The Toyota 3L 2.8L diesel engine, although reliable, was designed in an era before modern turbocharging became a standard feature. This turbo kit captures wasted exhaust energy that usually exits as black, unburnt fuel smoke and converts it into usable power. The result is dramatically improved performance without compromising engine longevity.

The recommended power level, as adjusted on the chassis dynamometer, is a 30% torque and 30% horsepower improvement above standard engine specifications. These figures have not been shown to shorten engine life or increase fuel consumption. In fact, fuel consumption figures have shown an improvement of approximately 10% due to more complete combustion.

Key Performance Improvements:

• Power: Increases from stock 91 HP to approximately 118 HP
• Torque: Increases from stock 188 N·m to approximately 245 N·m
• Fuel Economy: 10% improvement with 100-120 km (60-75 miles) additional range
• Emissions: Nearly zero black smoke under load conditions
