Kinugawa TD04L-13T 6cm Turbo for Isuzu 4JG2 / 4JG2T / 4JH1 3.0–3.1 Diesel – 130–180HP / +30% Torque

The Kinugawa TD04L-13T 6cm Turbocharger is the most response-focused option in the Kinugawa TD04L upgrade range for compatible Isuzu 4JG2, 4JG2T and 4JH1 diesel engines. Designed for drivers who prioritise quick spool-up, low-RPM response and usable torque, it provides a practical upgrade over the original IHI turbocharger without moving to an unnecessarily large compressor for a mildly tuned engine.

Kinugawa rates the TD04L-13T at approximately 130–180HP crank horsepower for diesel applications and positions it as the +30% torque configuration within this Isuzu turbo range.

The turbo uses a 40.7 / 56mm 13T compressor wheel, 41.3 / 47.0mm TD04L turbine wheel and compact 6cm / A/R .41 single-scroll turbine housing, helping retain strong exhaust-gas velocity and responsive boost characteristics.

Power Capability: 130–180HP crank horsepower for diesel

Kinugawa Torque Rating: +30% torque configuration

Compressor: TD04L-13T Trim 53

Engine Compatibility: Isuzu 4JG2 / 4JG2T 3.1L and compatible 4JH1-TC 3.0L Diesel

Original Turbo Family: Compatible applications using IHI RHF4 / RHF4H / RHF5 / RHB5-style turbine connections.

Important: The 130–180HP figure represents turbocharger capability rather than guaranteed engine output. Actual power and torque depend on engine condition, fuelling, boost pressure, intercooling, exhaust flow and correct calibration.

Choose the Right Kinugawa Turbo for Your Isuzu

OFM4x4 offers four Kinugawa TD04L turbocharger configurations for compatible Isuzu 4JG2, 4JG2T and 4JH1 diesel engines. Choosing the correct turbo should be based on the required power level and how the vehicle is used rather than simply selecting the largest available compressor.

The TD04L-13T is the response-focused choice. Its smaller compressor is particularly suitable for vehicles where strong low-RPM performance, predictable boost response and everyday drivability are more important than maximum peak horsepower.

Why Choose the TD04L-13T?

The TD04L-13T is particularly well suited to road-driven, touring, towing and off-road Isuzu diesels that do not require the airflow capability of the larger 15G, 15T or 19T configurations.

• 130–180HP crank horsepower capability
• Kinugawa +30% torque configuration
• 40.7 / 56mm 13T compressor wheel

Vehicle & Engine Compatibility

The Kinugawa TD04L-13T is listed for compatible vehicles powered by Isuzu 4JG2 / 4JG2T 3.1L and 4JH1-TC 3.0L diesel engines.

The turbine housing can also suit compatible Isuzu or Mazda engine applications using the appropriate standard 4-bolt RHF4H, RHF5 or RHB5 turbine outlet arrangement.

Important: Multiple IHI turbocharger configurations were used across these engines and vehicles. Always compare the turbine inlet and outlet flange specifications with the original turbocharger before ordering.

4JH1-TC 3.0L Applications

Kinugawa specifically lists the Isuzu 4JH1-TC 3.0L diesel using the IHI RHF5 VIEK / VA430093 turbocharger and OE reference 8973544234, including compatible Isuzu D-Max, Holden Rodeo and Rodeo Pickup applications.

This means the TD04L-13T range is not restricted to the 3.1-litre Trooper / Bighorn platform and can also be suitable for selected 3.0-litre 4JH1 installations where the correct turbo flange configuration is present.

OE & Turbo Reference Numbers

Compatible OE references listed for the relevant applications include:

• 8971480760
• 8971480761
• 860010
• 860015
• 97086343
• 5T-614
• E180027

OE and turbo references should be used as a compatibility guide. Physical flange configuration should still be checked before ordering.

Technical Specifications

Available Configuration Options

The TD04L-13T can be configured to suit different performance priorities through its compressor wheel, turbine wheel and actuator pressure options.

Compressor Housing

Non Anti-Surge

The current Kinugawa TD04L-13T product configuration lists the standard Non Anti-Surge compressor housing.

• Compressor Inlet: 2.4 inch / 60mm
• Compressor Outlet: 2 inch / 50mm

Compressor Wheel Options

• Cast 6+6
• Billet 6+6
• Billet 11+0

The compressor wheel measures 40.7 / 56mm.

Kinugawa specifically identifies the different blade configurations according to their intended performance characteristics:

• 6+6 blade: better suited to low-end torque
• 11+0 blade: more focused towards top-end performance

For a typical 4x4, touring, towing or road-driven 4JG2 installation where low-RPM response is important, the 6+6 configuration is therefore particularly relevant.

Turbine Wheel Options

• 12 Blades STD
• 9 Blades STS

Both configurations use the 41.3 / 47.0mm TD04L turbine wheel.

Turbine-wheel design influences rotating inertia, exhaust flow characteristics, spool response and high-RPM performance, allowing the turbo configuration to be further matched to the intended vehicle use.

Spring / Actuator Pressure Options

The standard actuator pressure is:

1.0 bar / 14.7 PSI – Default

Alternative actuator pressures available are:

• 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 must be selected according to the engine specification, desired boost pressure and boost-control strategy. Installing a higher-pressure actuator does not by itself provide a safe increase in engine power.

Cooling Type

Oil & Water Cooled

The TD04L-13T centre housing uses engine oil for bearing lubrication together with engine coolant for additional thermal management.

40.7 / 56mm TD04L-13T Compressor

The TD04L-13T uses a relatively compact 40.7mm inducer / 56mm exducer compressor wheel.

The smaller compressor size is one of the main reasons for choosing the 13T over the larger turbochargers in the range. Less compressor mass and lower airflow requirements make it particularly suitable where rapid boost response and usable low-RPM torque are the priorities.

This makes the TD04L-13T particularly attractive for:

• Daily-driven Isuzu 4x4s
• Touring vehicles
• Overlanding builds
• Towing applications
• Off-road vehicles
• Mild performance upgrades
• Vehicles running larger tyres
• Vehicles carrying additional accessories or equipment
• Drivers prioritising response over maximum peak horsepower

6cm / A/R .41 Turbine Housing

The TD04L-13T uses a compact 6cm / A/R .41 single-scroll turbine housing.

Turbine housing size has a major influence on turbocharger response. A relatively small turbine housing maintains higher exhaust-gas velocity at lower engine speeds, helping the turbine accelerate quickly and produce boost earlier.

This complements the relatively small 13T compressor and makes the TD04L-13T the most response-oriented option in this four-turbo range.

Factory Manifold & Downpipe Fitment

The TD04L-13T is designed to bolt to compatible factory manifold and downpipe arrangements.

The turbine side uses:

• Standard RHF4H / RHF5 turbine inlet
• Standard RHF4H / RHF5 / RHB5 4-bolt turbine outlet
• 6cm / A/R .41 single-scroll turbine housing
• Internal wastegate

Because several IHI turbocharger configurations exist across these vehicles and engines, always compare the flange arrangement before ordering.

Larger Compressor Inlet & Outlet

Although designed around compatible factory turbine-side connections, the Kinugawa compressor housing uses larger intake and charge-air connections than the standard turbocharger on many applications.

• Compressor Inlet: 2.4 inch / 60mm
• Compressor Outlet: 2 inch / 50mm

Suitable aftermarket silicone reducers or adapter hoses can be used where required to connect the turbocharger to the vehicle's intake and intercooler system.

Journal Bearing Construction

The TD04L-13T uses a proven journal-bearing centre section.

Correct oil supply is critical to turbocharger reliability. Clean engine oil, adequate oil pressure and an unrestricted oil-return path should be confirmed during installation.

If the previous turbocharger failed, the oil feed, oil return, intake and intercooler system should be inspected carefully before installing the replacement turbo.

Oil & Water Cooling

The Kinugawa TD04L-13T uses both engine oil and coolant.

Oil provides lubrication to the journal-bearing assembly, while coolant circulating through the centre housing assists with thermal management.

The turbo package includes the relevant oil and water line components to assist installation.

130–180HP Performance Capability

The TD04L-13T is rated at approximately 130–180HP crank horsepower for diesel applications.

This makes it particularly appropriate for mild-to-moderate 4JG2 and 4JH1 performance builds where increasing usable torque and response is more important than chasing maximum peak output.

The quoted horsepower figure represents turbocharger airflow capability and is not a guaranteed engine-output figure.

Actual performance depends on:

• Engine condition
• Fuel-system capability
• Fuel calibration
• Boost pressure
• Intercooler efficiency
• Air-intake restriction
• Exhaust flow
• Exhaust gas temperature
• Engine cooling
• Supporting modifications

TD04L-13T vs TD04L-15G

The next step in the range is the Kinugawa TD04L-15G.

Choose the TD04L-13T if quick spool, low-RPM response, daily drivability and a mild performance increase are the main priorities.

Choose the TD04L-15G if you want additional airflow and approximately 150–200HP capability while retaining good response.

TD04L-13T vs TD04L-15T & TD04L-19T

The TD04L-15T and TD04L-19T move progressively further towards increased airflow and maximum power capability.

The TD04L-13T makes more sense where:

• The engine has mild supporting modifications
• Low-RPM torque is important
• The vehicle spends significant time on the road
• The vehicle is used for towing or touring
• Off-road throttle response is important
• Maximum peak horsepower is not the objective

The larger options become more appropriate as the desired horsepower increases and the engine receives the fuelling, intercooling, exhaust and calibration required to make use of the additional airflow.

• TD04L-19T – 200–250HP / +60% Torque – maximum airflow and performance

Supporting Modifications

One advantage of the TD04L-13T is that it is suitable for relatively mild performance builds. However, the engine and supporting systems must still be in good condition and correctly configured.

Depending on the intended power level, supporting upgrades may include:

• Correct fuel-system calibration
• Intercooler upgrade
• Free-flowing exhaust system
• Improved air intake
• Appropriate boost control
• Boost-pressure monitoring
• Exhaust-gas-temperature monitoring
• Cooling-system inspection
• Engine-condition checks before tuning

Professional installation and tuning are recommended for performance applications.
