The Legendary TD42 Engine: A Comprehensive Guide to Nissan's Turbo Diesel Marvel
The Nissan TD42 engine, introduced in the GQ Patrol in 1988, has become an icon in the off-roading community due to its durability and reliability. This 4.2-liter six-cylinder diesel engine features a cast-iron block and cylinder head, designed to endure the harshest conditions. Let's dive into the details that make this engine a legend among 4WD enthusiasts.Power and Performance
The early models of the TD42, known as "Silvertop," produced 85kW and 260Nm of torque. Despite these modest numbers, the engine's construction allowed it to be a favourite for aftermarket turbocharging, significantly boosting performance. The GU Patrol of 1997 reintroduced the TD42 with factory turbocharging (TD42T3), featuring thicker pistons and more robust components, yielding 114kW and 330Nm. This upgrade made the engine more reliable under boosted conditions.Upgrading the Power with TD42 Performance Upgrades
The TD42’s versatility is highlighted by its various configurations. With modifications, these engines can achieve impressive power gains, such as the GTurbo TD42 upgrades, which can boost power up to 220KW and 600Nm with the right setup. These upgrades often include high-flow exhaust systems, upgraded intercoolers, and performance turbochargers, transforming the TD42 into a true performance beast. We gave this setup a run and returned a whopping 255HP and 617Nm Torque.
