Land Cruiser 1HD Turbo Range – Budget, Hybrid & Ultimate Tiers

OFM4x4 offers a complete Kinugawa turbo range for Toyota Land Cruiser 1HD diesel engines, from stock-style replacement through to extreme-performance builds.

Budget Tier – OEM Replacement

This Kinugawa CT26 is the Budget Tier option within the OFM4x4 Land Cruiser 1HD turbo range.

It is intended for owners who are happy with the original performance characteristics of their Land Cruiser but need to replace an old, worn or failed factory turbocharger.

Rather than requiring changes to the exhaust manifold, dump pipe or compressor plumbing associated with many larger aftermarket turbochargers, the CT26 retains a stock-type compressor housing and bolt-on CT26 turbine housing.

This makes it particularly suitable for:

• Standard or lightly modified Toyota Land Cruiser 80s
• Daily-driven vehicles
• Touring and overland vehicles
• Restoration projects
• Owners replacing a worn original CT26
• Vehicles where factory-style response is preferred
• Customers who do not require a high-horsepower turbo conversion

Vehicle Compatibility

Replacement Toyota Turbo References

The Kinugawa CT26 is designed as a replacement for the following Toyota turbocharger references:

• 17201-17010
• 17201-17020
• 17201-17030

Always confirm the existing turbocharger and vehicle specification before ordering where the vehicle has previously been modified or undergone an engine conversion.

Technical Specifications

Available Configuration Options

Although this is the OEM-style replacement turbo, Kinugawa provides useful compressor and turbine wheel choices that allow the replacement turbo to be configured according to customer preference.

Compressor Housing

Bolt-On Stock-Type Compressor Housing

The CT26 OEM replacement retains the factory-style compressor housing arrangement rather than using the larger 3-inch or 4-inch compressor covers found on the Ultimate Tier performance turbos.

This is one of the main advantages for customers looking for straightforward stock-style installation.

Compressor Wheel Options

• Cast 5+5
• Billet 6+6

Both configurations use the stock-type 41.8 / 65mm compressor wheel dimensions.

Cast 5+5 is the closest choice to a conventional OEM-style replacement configuration.

Billet 6+6 provides an upgraded billet compressor option while retaining the same general stock-style turbo format and wheel dimensions.

Turbine Wheel Options

• 10 Blades STD
• 9 Blades STS

The turbine wheel measures 51.9 / 67.9mm and is manufactured from Inconel 713.

The STD configuration provides the conventional turbine arrangement, while the STS option provides an alternative turbine blade design for customers wanting to alter the turbine's flow and response characteristics.

Spring / Actuator Pressure

The standard Kinugawa actuator setting is:

1.0 bar / 14.7 PSI – Default

Alternative actuator pressures can be supplied:

• 0.3 bar
• 0.5 bar
• 0.8 bar
• 1.0 bar – Default
• 1.2 bar
• 1.5 bar
• 1.7 bar
• 2.0 bar

Important: Actuator pressure should be selected according to the engine configuration and boost-control strategy. Installing a stronger actuator does not automatically create safe additional engine power.

Cooling Type

Oil & Water Cooled

The Kinugawa CT26 uses both engine oil and coolant through the turbocharger centre housing.

Engine oil provides bearing lubrication while coolant circulation assists with heat management.

Stock-Type 41.8 / 65mm Compressor

The CT26 OEM replacement uses a 41.8mm inducer / 65mm exducer compressor wheel, retaining stock-type dimensions appropriate for the original Land Cruiser turbo application.

This is considerably smaller than the compressor wheels used by the Ultimate Tier TD05H and TD06H turbos and is deliberately matched to the requirements of a standard or mildly modified 1HD engine.

The primary objective is therefore:

• Factory-style boost response
• Good low-RPM driveability
• Appropriate airflow for a standard engine
• Straightforward installation
• Reliable replacement of the original turbocharger

Cast 5+5 vs Billet 6+6 Compressor

Kinugawa gives customers a choice between a conventional Cast 5+5 compressor and an upgraded Billet 6+6 wheel.

51.9 / 67.9mm Inconel 713 Turbine

The turbine wheel measures 51.9 / 67.9mm and is manufactured from Inconel 713, a high-temperature nickel-based alloy commonly used for turbocharger turbine components.

Customers can select between the standard 10-blade design and Kinugawa's 9-blade STS alternative.

7cm Turbine Housing for Responsive Spool

The Kinugawa CT26 replacement uses a 7cm / A/R .49 turbine housing.

Kinugawa compares this with the stock approximately 8cm housing and describes the smaller 7cm nozzle area as providing faster spool response.

For a standard or mildly modified Land Cruiser, this makes the replacement turbo particularly well suited to maintaining strong low-RPM response and everyday driveability.

Stock-Type Bolt-On Compressor Housing

Unlike the Ultimate Tier performance turbochargers, this CT26 retains a bolt-on stock-type compressor housing.

This means customers replacing their original turbo do not need to adopt the large 3-inch or 4-inch compressor inlet arrangements used by the higher-output TD05H and TD06H products.

This significantly simplifies installation on a standard vehicle.

CT26 Bolt-On Turbine Housing

The exhaust side also retains the Toyota CT26 mounting arrangement:

• Toyota CT26 4-bolt turbine inlet
• Toyota CT26 4-bolt turbine outlet
• Internal wastegate
• Bolt-on stock-type turbine housing

This allows the replacement turbocharger to connect to the compatible original exhaust manifold and exhaust-side hardware without converting to an unrelated turbine flange.

Journal Bearing Construction

The CT26 OEM replacement uses a journal-bearing centre section.

This traditional turbocharger bearing arrangement is robust and well suited to a diesel 4x4 application when supplied with clean oil at the correct pressure and unrestricted oil return.

Oil & Water Cooling

The turbocharger is both oil and water cooled.

Correct connection of the oil and coolant systems is essential during installation.

When replacing an old failed turbocharger, the oil supply and return lines should also be inspected for contamination, carbon build-up, restriction or damage before the new unit is installed.

Designed to Restore Factory-Style Performance

This CT26 is not intended to compete directly with the 200HP+ TD05H and TD06H performance turbos.

Its purpose is different: to provide a quality replacement where the original CT26 has become worn, damaged or unreliable.

Common signs of a worn turbo may include:

• Excessive shaft play
• Oil leakage into the intake or exhaust
• Blue or grey exhaust smoke
• Reduced boost pressure
• Loss of engine performance
• Unusual turbocharger noise
• Slow or inconsistent boost response

Where the engine remains standard and the customer simply wants the Land Cruiser performing correctly again, the OEM replacement CT26 is the most logical option in the range.

Budget Tier vs Hybrid Tier

Choose this CT26 OEM Replacement if the objective is to replace a worn factory turbo and retain standard-style performance and installation.

Choose the CT26-GT3071R Hybrid if you want a noticeable performance upgrade while retaining the convenience of a CT26-based turbo package.

Budget Tier vs Ultimate Tier

The Ultimate Tier TD05H and TD06H turbochargers are intended for customers who want significantly greater airflow and power capability and are prepared to make the supporting modifications required.

The available Ultimate Tier options are:

• TD05H-16G – Up to 200HP – responsive daily-driver upgrade
• TD05H-18G – 200–250HP – balanced all-round performance
• TD05H-20G – 250–300HP – higher-output touring and performance
• TD05H-16K – 250–330HP – quick-spool billet high-power option
• TD05H-18K – 350–400HP – extreme-performance setup
• TD06H-25G – 350–380HP – large TD06H turbine and high-flow configuration

If your vehicle is standard and you do not intend to modify the fuel system, intercooler, intake, exhaust and engine calibration to support significantly higher airflow, the CT26 OEM replacement is generally the more appropriate choice.

When Should You Upgrade Instead?

If you are replacing a failed turbo but also plan to increase engine performance, it may be worth considering the Hybrid or Ultimate Tier instead of purchasing another stock-style CT26.

The most appropriate turbo depends on:

• Target horsepower
• Engine specification
• 1HD-T or 1HD-FT configuration
• Fuel-system capability
• Intercooler specification
• Exhaust system
• Vehicle weight
• Towing requirements
• Desired spool characteristics
• Road, touring, off-road or competition use
