TD04H-15G Turbocharger

The GReddy TD04H-15G turbocharger leverages GReddy Spec. Mitsubishi Heavy Industries technology, renowned for its superior quality and reliability in the industry. This unit features a robust center cartridge and an exceptionally large, free-floating bushing with a substantial center shaft. GReddy posits this design offers advantages over standard bushing turbos and even many ball-bearing types, providing a durable and high-performing core. GReddy emphasizes that peak horsepower numbers, large external dimensions, and maximum boost levels are not the sole indicators of performance; properly sized housings and wheels are crucial for usable, drivable power. The TD04H-15G, with its 8.5 cm² exhaust housing, is capable of supporting an output of 200-300 horsepower. It utilizes oil-only center cartridges, simplifying installation and enhancing reliability when proper turbo timing and oil maintenance are observed. This design also minimizes strain on the engine's coolant system. While specific vehicle fitment is not detailed in the provided evidence, this turbocharger is often discussed in the context of upgrade kits for vehicles like the Nissan 300ZX Z32. Performance gains are expected, especially after upgrading supporting components such as the exhaust, intake, blow-off valve, and intercooler, alongside adding more fuel and boost.
