The Toyota CT26 turbocharger (OEM 17201-17010) is a water-cooled induction unit specifically designed for the 1HD-T 4.2-liter turbo diesel engine. It features an Inconel 713C turbine wheel and fits Land Cruiser HDJ80, HDJ81 and Coaster HDB50 applications.
VSR balanced and ready for global export.
The Toyota CT26 turbocharger (OEM 17201-17010) is the definitive induction component for the legendary 1HD-T 4.2L inline-six turbo diesel engine. Engineered to meet Toyota’s rigid QDR (Quality, Durability, and Reliability) standards, this turbocharger is essential for maintaining the high torque output required by Land Cruiser HDJ80 and HDJ81 series owners. Unlike the intercooled 1HD-FTE or the smaller 2L-T variants, this Toyota CT26 diesel turbo is specifically clocked for the non-intercooled 1HD-T manifold, ensuring a perfect bolt-on fit for classic 80-series restorations and commercial Coaster HDB50 bus fleets.
To combat the extreme thermal loads of a 4.2L engine, our CT26 units are manufactured with an Inconel turbine wheel turbo, providing exceptional resistance to high exhaust gas temperatures and preventing thermal fatigue cracking in the turbine housing. Common symptoms of failure in aging 1HD-T units, such as oil leakage into the intake, high-pitched whistling, or boost loss, are directly addressed by our precision journal bearing system and water-cooled center housing. This high-standard metallurgy is critical for vehicles undergoing a Land Cruiser 80 turbo upgrade or heavy-duty engine rebuild.
As a premier supplier of Toyota diesel turbo wholesale solutions, every unit is VSR (Vibration Sorting Rig) balanced to 150,000 RPM. This rigorous balancing eliminates rotational harmonics that lead to premature seal failure. Whether you are performing a 1HD-T turbo replacement for a remote mining vehicle in Australia or restoring a fleet of HDB51 buses, our CT26 17201-17010 provides the reliable boost performance needed for demanding long-haul and off-road applications.

The 17201-17010 is specifically for the 12-valve 1HD-T engine, which is non-intercooled from the factory. The 17201-17040 is used on the later 24-valve intercooled 1HD-FTE. While they share the CT26 name, the compressor housing outlet and turbine housing wastegate orientations differ. Installing the wrong unit on an HDJ80 will result in misalignment of the air intake and intercooler piping.
On the 1HD-T, blue smoke is often caused by failed turbo journal bearing seals allowing oil to bypass into the compressor or turbine housing. White smoke can indicate coolant passing through a cracked center housing. Our units use upgraded high-temperature seals and undergo pressure testing up to 1.5x operating range to prevent these common failure modes.
The four nuts securing the CT26 turbo to the exhaust manifold should be tightened to 44 Nm (32 ft·lb). The oil feed union bolt requires 22 Nm (16 ft·lb). To avoid catastrophic shaft damage, you must “oil prime” the turbo by filling the oil inlet and spinning the turbine by hand before starting the engine to ensure the floating bearings are lubricated.
