Kinugawa TD05H-16K 7cm Turbo for Toyota Land Cruiser 1HD-T / 1HD-FT / 1HD-FTE – 250–330HP

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

Rated by Kinugawa for approximately 250–330HP potential crank / flywheel power, the TD05H-16K combines a modern 49.6 / 68mm billet 7+7 compressor wheel with the responsive 7cm / A/R .49 turbine housing. This gives the 16K considerably more power headroom than the 16G, 18G and 20G configurations while retaining the compact turbine housing that helps maintain strong spool characteristics.

The 16K is particularly attractive for modified Land Cruisers where the aim is to combine quick response with serious power capability, rather than choosing a larger turbo focused primarily on maximum top-end output.

Power Capability: 250–330HP potential crank / flywheel power

Recommended Use: Quick-spool, high-power touring, towing and performance builds.

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

Important: Turbocharger power capability is not a guaranteed engine output. Actual performance depends heavily on engine condition, fuel delivery, 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 the turbocharger to be selected according to power target, spool characteristics and intended vehicle use.

The TD05H-16K is the standout option for owners who want approximately 250–330HP capability without moving immediately to the more extreme 18K or TD06H-25G configurations.

Why Choose the TD05H-16K?

The TD05H-16K differs significantly from the conventional 16G, 18G and 20G compressor family.

Rather than simply increasing the diameter of a conventional G-series compressor, the 16K uses a modern billet 7+7 compressor wheel with point-milled free-surface blade geometry.

This combination is designed to provide strong airflow efficiency and substantial power capability while retaining useful response characteristics.

• 250–330HP potential crank / flywheel capability
• 49.6 / 68mm billet 7+7 compressor wheel
• Point-milled free-surface compressor blade design
• Compact 7cm / A/R .49 turbine housing
• 56.0 / 49.2mm TD05H turbine wheel
• CT26-style turbine inlet and outlet
• Strong response for a high-output turbo
• Excellent power headroom compared with the G-series options
• Multiple turbine wheel configurations available
• Multiple actuator spring pressures available
• Oil and water cooled

Engine & Vehicle Compatibility

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

For the Toyota Land Cruiser 80 Series, the Kinugawa TD05H-16K is designed around the 1991–1997 HDJ80 / HDJ81 / HDJ82 1HD-T and 1HD-FT 4.2-litre turbo diesel applications.

It is designed as a replacement and performance upgrade for Toyota turbo references:

• 17201-17010
• 17201-17030

The turbine housing retains the same basic Toyota CT26-style inlet and outlet arrangement as the factory turbocharger, reducing the amount of exhaust-side fabrication required compared with converting to a completely different turbo mounting system.

1HD-FTE Compatibility

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

For vehicles using Toyota turbo reference 17201-17040, this includes applicable:

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

For these applications, the compressor housing configuration should be confirmed according to the vehicle installation. The performance 3-inch compressor housing may be retained where suitable, or a different housing arrangement may be required.

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

Technical Specifications

Available Configuration Options

The TD05H-16K has a different option structure from the 16G, 18G and 20G products. The compressor wheel is specifically the Billet 7+7 16K wheel, while the customer can choose compressor housing style, turbine wheel design and actuator pressure.

Compressor Housing Options

• Anti-Surge
• Non Anti-Surge

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

The anti-surge housing uses a ported compressor inlet configuration, while the non anti-surge version uses a conventional compressor cover.

Compressor Wheel

Billet 7+7

Unlike the 16G, 18G and 20G products, the current Kinugawa TD05H-16K listing does not offer separate cast 6+6, billet 6+6 or billet 11+0 compressor-wheel selections.

The 16K uses a dedicated 49.6 / 68mm billet 7+7 compressor wheel.

The wheel uses Kinugawa's point-milled free-surface machining, a manufacturing process designed to produce more complex blade geometry than conventional flank-milled ruled-surface machining.

Turbine Wheel Options

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

The turbine wheel measures approximately 56.0 / 49.2mm.

Turbine wheel choice affects turbine inertia, exhaust flow, spool behaviour and high-RPM efficiency, allowing the turbocharger to be configured towards different performance characteristics.

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

Cooling Type

Oil & Water Cooled

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

Billet 7+7 16K Compressor

The defining feature of the TD05H-16K is its 49.6 / 68mm billet 7+7 compressor wheel.

Unlike the progressively larger conventional G-series compressors, the 16K uses a different blade geometry and manufacturing approach intended to provide high airflow efficiency without requiring an excessively large rotating assembly.

This is what allows the TD05H-16K to offer approximately 250–330HP potential power capability while maintaining a strong focus on response.

Point-Milled Free-Surface Compressor Technology

The Kinugawa 16K compressor wheel uses point-milling rather than conventional flank milling.

Point milling allows the compressor blades to use a more complex free-surface geometry. Kinugawa describes this approach as being intended for higher-efficiency turbocharger compressor designs.

For the driver, the objective is a compressor that can combine:

• Strong airflow capability
• Efficient compression
• High power potential
• Useful response characteristics
• Reduced need for an excessively large compressor wheel

7cm Turbine Housing – High Power Without Giving Up Response

Despite its 250–330HP power capability, the TD05H-16K retains the compact 7cm / A/R .49 turbine housing.

Kinugawa compares this with the approximately 8cm factory CT26 turbine housing.

The smaller turbine housing increases exhaust-gas velocity through the turbine and is intended to improve spool response.

This is particularly valuable on a heavy Land Cruiser where low- and mid-range response can be just as important as maximum horsepower.

TD05H Turbine – 56.0 / 49.2mm

The TD05H-16K uses a turbine wheel measuring approximately 56.0 / 49.2mm.

Three turbine-wheel designs are available:

• 12-Blade STD
• 9-Blade STS
• 10-Blade STS 55

This provides additional flexibility when choosing the balance between spool characteristics and exhaust-flow capability.

CT26-Style Bolt-Up Turbine Housing

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

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

For compatible 1HD-T and 1HD-FT installations, this means the turbo is designed to connect to the factory exhaust manifold and dump-pipe arrangement rather than requiring a completely custom T3 or V-band conversion.

Important 3-Inch Compressor Inlet

The compressor housing uses a substantial 3-inch inlet.

On applicable 1HD-T and 1HD-FT installations, the original air-filter / turbo inlet pipe must therefore be modified or replaced to suit the larger compressor connection.

The larger inlet reduces restriction and supports the greater airflow demands of the performance compressor.

Journal Bearing with 360° Performance Thrust Bearing

The TD05H-16K uses a journal-bearing centre housing with a 360-degree performance thrust bearing.

The 360-degree thrust system is particularly relevant on a performance turbocharger because increased compressor airflow and boost pressure create greater axial loading on the rotating assembly.

Oil & Water Cooling

The centre housing is both oil and water cooled.

Engine oil lubricates the journal-bearing system, while coolant circulation assists with thermal management of the turbocharger centre housing.

Correct oil supply, coolant circulation and turbo priming are essential during installation.

250–330HP Performance Capability

Kinugawa rates the TD05H-16K diesel configuration at approximately 250–330HP potential crank / flywheel power.

The stated maximum is calculated from compressor-map choke flow and represents the potential airflow capability of the turbocharger rather than guaranteed engine output.

Actual output depends on:

• Engine condition
• Fuel delivery
• Injection-pump or ECU calibration
• Boost pressure
• Intercooler efficiency
• Intake airflow
• Exhaust flow
• Exhaust gas temperature
• Ambient temperature and altitude
• Supporting engine modifications

Ideal for Quick-Spool High-Power Builds

The TD05H-16K is particularly attractive for owners who want substantially more power than the G-series turbos can comfortably provide while still keeping response high on a heavy Land Cruiser.

It is particularly suitable for:

• 250–330HP Land Cruiser builds
• High-performance touring vehicles
• Heavy towing builds
• Modified overland vehicles
• Large-tyre Land Cruisers
• Vehicles fitted with upgraded intercoolers
• Vehicles fitted with free-flowing exhaust systems
• Modified fuel-system applications
• Performance-oriented 1HD engines
• Drivers who still value spool response and road manners

TD05H-20G vs TD05H-16K

Choose the TD05H-20G if you want a conventional high-flow 20G setup targeting approximately 250–300HP.

Choose the TD05H-16K if you want approximately 250–330HP capability with a modern billet compressor and a strong focus on quick response.

TD05H-16K vs TD05H-18K

The next step in the range is the Kinugawa TD05H-18K, intended for approximately 350–380HP builds.

Choose the TD05H-16K if:

• Your target is approximately 250–330HP
• Quick spool remains an important priority
• The vehicle is still used regularly on the road
• You want strong power without moving into an extreme 350HP+ build

Consider the TD05H-18K if:

• Your target is approximately 350–380HP
• The engine is being built for extreme performance
• Maximum airflow becomes a higher priority than everyday response

Supporting Modifications

At the TD05H-16K's 250–330HP capability level, supporting engine modifications and correct calibration become increasingly important.

Depending on the target output, supporting upgrades may include:

• Correct injection-pump or ECU calibration
• Fuel-system upgrades
• Upgraded intercooler
• Free-flowing 3-inch exhaust system
• Improved air intake
• Correct boost-control system
• Boost-pressure monitoring
• Exhaust-gas-temperature monitoring
• Cooling-system assessment
• Engine-condition checks before tuning

Professional tuning is strongly recommended after fitting a performance turbocharger.
