1HZ Turbo Upgrade Kit Built for Boosted LandCruisers
If you’re planning a 1HZ turbo upgrade, don’t risk running factory internals under boost. This engine rebuild kit is designed specifically for turbocharged Toyota 1HZ engines, providing the strength and reliability needed to safely handle increased power and torque.
This kit is ideal for HZJ70, HZJ80, and HZJ105 Series LandCruisers running aftermarket turbo setups on the 1HZ engine platform.
What’s Included in the Kit?
All components are high quality and performance-rated for turbocharged builds:
ARCO Pistons – Turbo-spec pistons available in Standard, 0.50mm, and 1.00mm
33mm gudgeon pin diameter
STONE Full Gasket Set – Reliable sealing solution for complete rebuilds
CHERRY Head Gasket – Available in 3 or 5 notch variations to suit your build
TP (TEIKOKU) / NPR Piston Rings – Precision-engineered for durability under boost

Vehicle Compatibility
This 1HZ turbo upgrade kit suits all Toyota LandCruisers fitted with a 1HZ engine, including:
HZJ70 Series
HZJ80 Series
HZJ105 Series
Important: This kit is not intended for standard naturally aspirated 1HZ builds. It is specifically designed for those undergoing a turbo upgrade.
Why Choose This 1HZ Turbo Upgrade Kit?
When you boost a 1HZ engine, standard internals can’t handle the heat and pressure. Our kit replaces weak points with turbo-rated pistons, rods, and hardware, ensuring your engine stays strong and reliable under turbocharging.
A proper 1HZ turbo upgrade requires more than just bolting on a turbo — the bottom end must be built to take it. This kit gives you the confidence to turn up the power without sacrificing engine life.
