Simpson Off-Road Engineering presents our full turbocharger kit for 1HZ Owners - packaging our existing and proven 1HZ-T accessories, with a water-cooled billet wheel CT26 Turbocharger from Arashi Dynamics. This package includes everything needed to turn your 1HZ into a reliable tourer with power levels on par with a standard VDJ Landcruiser, for a fantastic price point.

The turbo we’ve chosen for this package is the proven Arashi billet wheel CT26. This turbo takes design cues from the 1HD-T and 1HD-FT factory Toyota turbo with similar compressor and turbine specs, but raises the bar with quicker spool and more boost - providing impressive, yet reliable power figures after tuning (standard fuel pump: 140RWHP, upgraded fuel pump: 180RHWP+).

Our 1HZ turbocharger kits consist of the following:

• Simpson Off-Road Engineering 1HZ / CT26 Manifold Adaptor Kit

• Simpson Off-Road Engineering 3” Intake Hose Kit, with Crankcase Breather hose option included

• Simpson Off-Road Crossover Pipe Link kit, with Boost Reference Port fitting option included

• Simpson Off-Road Engineering Oil + Water Cooling Line kit

• Arashi Dynamics CT26 Billet Wheel Turbocharger, pre-set to an ideal 1HZ boost level of 16 Psi (note, additional wastegate springs are included if a different boost level is required)

Please note, we recommend professional installation during fitment of turbocharger to ensure setup is correct - boost settings vary depending on fuel pump tune, intercooler fitment, etc. Details on all Simpson Off-Road Engineering products are available on their product pages on the website. If installing an intercooler, please select the ‘without crossover link option’.

All that’s left is to choose an exhaust setup - either a custom system from the turbo back (we can supply a laser cut CT26 Exhaust Flange if required) or perhaps an off-the shelf, factory-style HDJ exhaust system (please note, if pursuing this option, it is likely cutting/rewelding the supplied dump pipe to suit the new angle of the manifold adaptor will be required).

The turbocharger in this kit is directly sourced from Arashi Dynamics, as such Simpson Off-Road Engineering acts as a supplier only. Turbocharger is covered by Arashi’s 1 year warranty (turbocharger components only). Any and all turbo-related enquiries or warranty discussions will be forwarded to Arashi Dynamics beyond supply. Please note, we recommend professional installation and tuning to ensure correct boost pressure and fuelling is achieved.
