Original Velocity Race Innovations (VR) Product – Made in Malaysia

 

The Mitsubishi 4G92 / 4G93 Billet Aluminium Complete ITB Assembly is a performance-oriented Individual Throttle Body system developed for Mitsubishi 4G92 and 4G93 engine applications. Designed for naturally aspirated performance builds, this complete Mitsubishi ITB assembly is intended for applications where sharper throttle response, increased airflow potential and precise throttle control are important.

 

Unlike a conventional intake system that uses a single throttle body connected to a shared intake plenum, an Individual Throttle Body system provides an individual throttle body for each cylinder. This creates a direct throttle-control arrangement and gives the engine a different intake configuration compared with a conventional single-throttle-body setup.

 

The Mitsubishi 4G92 / 4G93 Billet Aluminium Complete ITB Assembly is available with 45 mm, 50 mm and 55 mm throttle body configurations. These options allow the Mitsubishi 4G92 ITB or Mitsubishi 4G93 ITB setup to be selected according to the engine displacement, cylinder-head flow, camshaft specifications, RPM range and intended application.

 

Manufactured using CNC-machined billet aluminium components, this 4G92 / 4G93 Individual Throttle Body system provides a strong, lightweight and professional solution for naturally aspirated performance engines, high-RPM builds, track cars, race cars and competition applications.

 

Whether you are developing a naturally aspirated 4G92 engine or a performance 4G93 engine, the Mitsubishi 4G92 / 4G93 ITB conversion can form part of a complete engine development package where the intake system, cylinder head, camshaft, exhaust, fuel system and ECU are configured to work together.

PERFORMANCE BENEFITS

An Individual Throttle Body system gives each cylinder its own dedicated throttle instead of using a single throttle body connected to a shared intake plenum. The Mitsubishi 4G92 / 4G93 Billet Aluminium Complete ITB Assembly is designed around this individual-cylinder throttle arrangement.

 

Depending on the complete engine combination and ECU tuning, a Mitsubishi ITB setup can provide:

• Sharper throttle response
• More immediate engine response
• Improved throttle control
• Improved airflow characteristics at high RPM
• Increased tuning flexibility
• Improved intake sound and engine character
• Greater airflow potential for high-performance engines
• Individual throttle control for each cylinder

 

A Mitsubishi 4G92 ITB or Mitsubishi 4G93 ITB setup can be particularly suitable for naturally aspirated engines that are designed to operate at higher RPM.

 

The intake system can also complement other performance modifications such as camshafts, cylinder-head upgrades, compression upgrades and performance exhaust systems. Actual performance results will depend on the complete engine combination and ECU calibration.

• 55 mm ITB

 

45 MM ITB

The 45mm ITB configuration is suitable for smaller-displacement or milder performance combinations where throttle control, response and drivability are important.

This configuration can be considered for engines where the overall airflow requirement does not require a larger throttle opening.

 

50 MM ITB

The 50mm ITB configuration provides a versatile option for moderately modified 4G92 and 4G93 engines.

It offers a balance between airflow capacity and throttle control and can be suitable for naturally aspirated performance applications where the engine has supporting modifications.

 

55 MM ITB

The 55mm ITB configuration is designed for higher-output and high-RPM applications where increased airflow capacity is required.

 

This configuration is more suited to engines with supporting modifications and an overall engine combination designed to operate at higher RPM. The correct throttle body size should always be selected according to the engine’s actual airflow requirements. A larger ITB diameter does not automatically produce more power. Engine displacement, cylinder-head flow, camshaft specifications, compression ratio, exhaust system and intended RPM range should all be considered.

PROFESSIONAL INSTALLATION & TUNING

Professional installation is recommended for the Mitsubishi 4G92 / 4G93 Billet Aluminium Complete ITB Assembly. An ITB conversion normally requires appropriate throttle linkage setup, vacuum reference, injector positioning, ECU configuration and calibration.

 

The individual throttle bodies should be properly synchronised after installation to ensure consistent operation between cylinders. The throttle position sensor should also be correctly configured with the ECU so that throttle position is accurately recognised throughout the operating range.

 

For best results, the engine should be properly tuned using suitable engine-management calibration equipment or on a

 

Depending on the engine configuration, installation and tuning may involve:

• Throttle linkage setup
• Throttle-body synchronisation
• TPS calibration
• Injector positioning
• Fuel calibration
• Ignition calibration
• Vacuum reference setup
• Idle control
• ECU configuration
• MAP sensor configuration where applicable
• ITB tuning strategy

 

Proper ECU calibration is an important part of the Mitsubishi 4G92 / 4G93 ITB conversion.

 

 

WHY UPGRADE TO ITB?

The Mitsubishi 4G92 / 4G93 Billet Aluminium Complete ITB Assembly changes the intake configuration from a conventional shared-throttle arrangement to an individual throttle body system. Each cylinder receives its own throttle body, providing a dedicated throttle opening for each intake runner.

 

For naturally aspirated performance engines, this configuration can provide a different throttle response and intake character compared with a conventional single-throttle-body intake system.

 

Potential benefits include:

• Sharper throttle response
• More direct throttle control
• Improved engine response
• Stronger high-RPM airflow characteristics
• Increased tuning flexibility
• Enhanced intake sound
• Individual throttle control
• Motorsport-oriented engine-bay appearance

 

The Mitsubishi 4G92 ITB and Mitsubishi 4G93 ITB configurations can be particularly relevant for performance engines that have been developed around higher RPM operation.

 

 

PERFORMANCE NOTES

The Mitsubishi 4G92 / 4G93 Billet Aluminium Complete ITB Assembly does not guarantee a specific horsepower increase by itself.

 

Actual performance depends on the complete engine combination.

Important factors include:

• Engine displacement
• Compression ratio
• Cylinder-head design
• Cylinder-head porting
• Cylinder-head airflow
• Camshaft specifications
• Valve train
• Exhaust system
• Fuel system
• Injector sizing
• Ignition system
• ECU configuration
• Engine RPM range
• ITB diameter
• Trumpet configuration
• ECU calibration

 

A larger throttle body does not automatically result in increased engine power. The engine must be capable of using the available airflow, and the ECU must be correctly calibrated for the new intake configuration.

 

For high-RPM naturally aspirated applications, the relationship between cylinder-head flow, camshaft characteristics, intake configuration and exhaust system is particularly important.
