Kinugawa TD05H-16G 7cm Turbo for Toyota Land Cruiser 1HD-T / 1HD-FT / 1HD-FTE – Up to 200HP

The Kinugawa TD05H-16G 7cm Turbocharger is a fast-spooling performance turbo upgrade for Toyota Land Cruiser models powered by the legendary 1HD-T, 1HD-FT and 1HD-FTE 4.2-litre turbo diesel engines.

Rated by Kinugawa for approximately 150–200HP potential crank / flywheel power, the TD05H-16G is the most response-focused turbo in our six-model Kinugawa Land Cruiser 1HD range. It is an excellent choice for daily-driven, touring, overland and off-road Land Cruisers where quick spool, low-RPM response and driveability are more important than chasing maximum peak horsepower.

The turbo combines a 48.3 / 68.0mm 16G compressor wheel with a 49 / 57mm TD05H turbine wheel and compact 7cm / A/R .49 turbine housing. The Toyota CT26-style 4-bolt turbine inlet and outlet help retain compatibility with the original-style exhaust manifold and dump-pipe arrangement on applicable 1HD installations.

Power Capability: 150–200HP potential crank / flywheel power

Recommended Use: Responsive daily driver, touring, overlanding and fast-spool performance builds.

Engine Compatibility: Toyota 1HD-T / 1HD-FT / 1HD-FTE 4.2L Turbo Diesel

Important: Maximum turbo power capability is not a guaranteed engine output. Actual performance depends on engine condition, fuelling, boost pressure, intercooling, intake and exhaust flow and correct tuning / calibration.

Choose the Right Kinugawa Turbo for Your Land Cruiser

OFM4x4 offers six Kinugawa TD05H/TD06H turbo options for Toyota Land Cruiser 1HD diesel engines, allowing selection of the turbocharger based on the intended power target and driving characteristics.

Engine & Vehicle Compatibility

Land Cruiser 80 Series – 1HD-T & 1HD-FT

For the Toyota Land Cruiser 80 Series, Kinugawa lists this turbo for 1991–1997 HDJ80 / HDJ81 / HDJ82 models equipped with the 1HD-T or 1HD-FT 4.2-litre turbo diesel.

It is designed as an upgrade for the following Toyota turbo references:

• 17201-17010
• 17201-17030

The CT26-style turbine housing is designed to bolt to the compatible factory exhaust manifold and dump pipe, reducing the amount of fabrication required compared with a completely different turbine housing format.

1HD-FTE Compatibility

Kinugawa also lists this TD05H-16G for the Toyota 1HD-FTE 4.2-litre turbo diesel.

For vehicles using the 17201-17040 turbo application, including the following:

• Toyota Land Cruiser HDJ78
• Toyota Land Cruiser HDJ79
• Toyota Land Cruiser HDJ100
• Toyota Land Cruiser HDJ105 / converted applications where applicable

Kinugawa advises confirming the required compressor housing configuration for the 1HD-FTE installation. The turbo can retain the performance 3-inch compressor housing where suitable, or the appropriate housing configuration can be selected for the application.

If ordering for a 1HD-FTE application, please confirm your vehicle model and current turbo configuration so the appropriate option can be supplied.

Technical Specifications

Available Configuration Options

The Kinugawa TD05H-16G can be configured with different compressor housing, compressor wheel, turbine wheel and actuator options. This allows the turbo to be tailored more closely to the intended driving style and engine setup.

Compressor Housing Options

• Anti-Surge
• Non Anti-Surge

The compressor housing has a 3-inch inlet and A/R .60 nozzle area.

The anti-surge housing provides a ported compressor inlet arrangement, while the non anti-surge option provides a conventional compressor cover configuration.

Compressor Wheel Options

• Cast 6+6
• Billet 6+6 – recommended where low-end torque and response are the priority
• Billet 11+0 – recommended where stronger top-end performance is the priority

The TD05H-16G compressor wheel measures 48.3 / 68.0mm.

Kinugawa specifically identifies the Billet 6+6 configuration with low-end torque and the Billet 11+0 configuration with top-end speed, allowing the same basic turbocharger to be tailored towards different driving characteristics.

Turbine Wheel Options

• 12 Blades STD
• 9 Blades STS
• 10 Blades STS 55

All options are based around the 49 / 57mm TD05H turbine wheel dimensions.

Turbine wheel design can affect spool characteristics, exhaust flow, backpressure and high-RPM performance, making the turbine wheel an important part of configuring the turbo for its intended use.

Spring / Actuator Pressure Options

The standard Kinugawa actuator is supplied at:

1.0 bar / 14.7 PSI – Default

Alternative actuator pressures available include:

• 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: The actuator spring pressure should be selected according to the engine specification, desired boost target and boost-control strategy. A higher actuator spring pressure does not by itself create safe additional engine power.

Cooling Type

Oil & Water Cooled

The TD05H-16G uses engine oil for bearing lubrication together with coolant circulation through the centre housing for additional thermal management.

How the Configuration Affects Turbo Response

Kinugawa identifies three principal factors that influence the driving characteristics of a turbocharger:

1. Turbine housing A/R – the most significant influence on spool characteristics
2. Turbine wheel design – affects inertia, exhaust flow and turbine efficiency
3. Compressor wheel design – affects airflow capacity, efficiency and the overall operating characteristics of the turbo

The compact 7cm / A/R .49 turbine housing used on this TD05H-16G is particularly relevant to its fast-spool character.

7cm Turbine Housing for Faster Response

The TD05H-16G uses a 7cm / A/R .49 turbine housing, compared with approximately 8cm / A/R .57 for the referenced stock CT26 configuration.

A smaller turbine housing generally increases exhaust-gas velocity through the turbine, allowing the turbocharger to respond sooner. The trade-off is that a smaller housing can ultimately restrict high-RPM flow compared with a larger turbine housing.

For the 16G's intended 150–200HP range, the 7cm housing complements the response-focused nature of the turbo particularly well.

48.3 / 68.0mm 16G Compressor

The TD05H-16G uses a 48.3mm inducer / 68.0mm exducer compressor wheel.

This represents a significant performance upgrade while remaining compact enough to support the responsive characteristics expected from the 16G configuration.

Customers can further tailor the compressor characteristics by choosing between:

• Cast 6+6
• Billet 6+6
• Billet 11+0

49 / 57mm TD05H Turbine

The turbine side uses a 49 / 57mm TD05H turbine wheel.

Three turbine designs are offered, allowing customers to select between the standard configuration and Kinugawa STS turbine wheel alternatives.

CT26-Style Bolt-On Turbine Housing

The turbine housing retains the Toyota CT26-style mounting arrangement:

• Toyota CT26 4-bolt turbine inlet
• Toyota CT26 4-bolt turbine outlet
• Internal wastegate

For compatible 1HD-T and 1HD-FT applications, this allows the turbo to bolt to the factory exhaust manifold and dump-pipe arrangement, reducing the fabrication normally associated with converting to a completely different turbo mounting system.

3-Inch Compressor Inlet

The performance compressor housing uses a substantial 3-inch inlet.

On applicable 1HD-T / 1HD-FT installations, the original compressor inlet / air-filter pipe will require modification or replacement to connect to the larger 3-inch inlet.

The larger compressor inlet helps reduce intake restriction and allows the upgraded compressor to receive the airflow required for increased performance.

Journal Bearing with 360° Performance Thrust Bearing

The TD05H-16G uses a journal bearing centre section with a 360-degree performance thrust bearing.

The 360-degree thrust arrangement is designed for performance turbocharger operation where increased boost and compressor loads can create greater axial loading on the rotating assembly.

Oil & Water Cooling

The turbocharger centre housing uses both oil and water cooling.

Engine oil provides lubrication to the journal bearing system, while coolant circulation assists with thermal management of the turbocharger centre housing.

Correct oil supply, coolant circulation and turbocharger installation procedures are essential for long-term reliability.

Up to 200HP Performance Capability

Kinugawa rates the TD05H-16G diesel configuration for approximately 150–200HP potential crank / flywheel power.

The manufacturer's maximum power figure is calculated from compressor-map choke flow and represents the potential airflow capability of the turbocharger rather than guaranteed vehicle output.

Actual engine performance will depend on:

• Fuel delivery
• Injection pump or ECU calibration
• Boost pressure
• Intercooler efficiency
• Intake airflow
• Exhaust system
• Engine condition
• Exhaust gas temperature
• Ambient conditions
• Supporting engine modifications

Ideal for a Responsive Land Cruiser Build

The TD05H-16G is particularly attractive for owners who want their Land Cruiser to feel stronger and more responsive without building the engine around an oversized high-horsepower turbo.

It is particularly well suited to:

• Daily driving
• Touring
• Overlanding
• Green-laning
• Off-road driving
• Moderate towing
• Vehicles running larger tyres
• Land Cruisers carrying touring equipment
• Drivers prioritising low-RPM response
• 150–200HP performance targets

TD05H-16G vs TD05H-18G

The next turbo in the range is the Kinugawa TD05H-18G, aimed at approximately 200–250HP.

Choose the TD05H-16G if:

• Your target is up to approximately 200HP
• Fast spool is the priority
• You want excellent everyday response
• You use the vehicle primarily for road, touring or off-road driving

Choose the TD05H-18G if:

• Your target is approximately 200–250HP
• You want greater airflow and top-end performance
• You want the most popular all-round performance option in the range

Depending on the desired output, supporting upgrades may include:

• Correct fuel system calibration
• Upgraded intercooler
• Free-flowing exhaust system
• Improved intake system
• Correct boost control
• Boost pressure monitoring
• Exhaust gas temperature monitoring
• Engine-condition checks
• Professional tuning / calibration

Professional tuning is strongly recommended after fitting a performance turbocharger.
