Nissan Micra K11 M24 Supercharger Conversion Kit

Fancy something a little different from the usual turbo conversion?

Our Nissan Micra K11 M24 Supercharger Conversion Kit has been developed to provide a cost-effective route into forced induction using the readily available M24 supercharger found on various VAG Group TFSI engines.

The kit provides the custom components required to physically integrate the M24 supercharger into the K11 engine setup, including our purpose-designed supercharger and throttle body adapters, belt drive components, intake system, bypass valve and associated hardware.

The result is a compact supercharger conversion designed around improved throttle response, torque and that unmistakable supercharger character.

⚠️ M24 Supercharger NOT Included

THE M24 SUPERCHARGER UNIT ITSELF IS NOT INCLUDED WITH THIS KIT.

The customer must source a suitable M24 supercharger separately.

These superchargers were used across various VAG Group TFSI applications and are readily available through used and aftermarket sources, helping keep the overall conversion relatively affordable.

As these units are commonly sourced second-hand, their condition should be checked carefully before installation.

The condition and service life of a customer-supplied used supercharger is outside the control of GizFab Motorsport Developments and is not covered by the warranty supplied with this conversion kit.

Why an M24 Supercharger?

The M24 provides an interesting alternative to the more conventional K11 turbo conversion.

A mechanically driven supercharger responds directly to engine speed rather than relying on exhaust gas energy to drive a turbine.

For the right build, this can provide a responsive and entertaining forced-induction setup with a distinctly different character to a turbocharged engine.

The M24 also benefits from being relatively easy to source, making replacement units and spare superchargers considerably more accessible than using a rare or application-specific unit.

Purpose-Designed Supercharger Adapter

The supplied adapter neck allows the M24 supercharger to be integrated into the K11 intake arrangement.

The adapter incorporates a pre-threaded:

M14 x 1.5 Sensor Port

This provides a convenient location for an aftermarket Intake Air Temperature (IAT) sensor.

Monitoring intake temperature is particularly important on this conversion because the standard kit does not incorporate an intercooler or aftercooler.

The sensor itself is not included unless specifically stated.

Throttle Body Adapter with Auxiliary Port

The supplied throttle body adapter incorporates an integrated:

1/8" NPT Threaded Port

This provides a convenient connection point for compatible aftermarket equipment such as a water-methanol injection system or other suitable boost-related accessories.

Any additional fittings, sensors or water-methanol equipment are not included unless specifically stated.

Larger Supercharger Pulley Supplied as Standard

One of the most important aspects of this conversion is supercharger speed.

The M24 incorporates an approximately 2:1 internal step-up drive within its snout.

This means the internal supercharger assembly is already rotating considerably faster than the external pulley speed may initially suggest.

Using an excessively small drive pulley can therefore cause the supercharger to operate at extremely high speeds as engine RPM increases.

This is why our kit is supplied with a larger supercharger pulley as standard.

The standard pulley selection has deliberately been chosen around a balance of:

• Boost Pressure
• Supercharger Speed
• Intake Air Temperature
• Engine Performance
• Reliability
• Supercharger Service Life

This is not simply a case of fitting the smallest pulley possible to make the biggest boost number.

⚠️ Smaller Pulley = More Boost AND More Heat

Smaller supercharger pulleys may be available for customers wanting to increase supercharger speed and boost pressure.

However, increasing supercharger speed also increases the amount of heat generated during compression.

More boost does not automatically mean more usable power.

As intake temperature increases, the engine becomes increasingly susceptible to:

• Reduced Air Density
• Reduced Power
• Detonation / Knock
• Ignition Timing Retard
• Increased Thermal Stress
• Increased Supercharger Stress
• Reduced Supercharger Service Life
• Potential Engine Damage

The smaller the pulley, the more carefully the complete engine combination needs to be considered.

⚠️ This Kit is NOT Intercooled

The standard M24 conversion has been designed without an intercooler or aftercooler.

This keeps the installation relatively simple and compact, but it makes intake temperature management particularly important.

Our recommended pulley has therefore been selected around maintaining a sensible balance between performance, supercharger speed and intake temperature.

Customers considering smaller pulleys and increased boost should pay particular attention to intake temperatures and engine calibration.

Water-methanol injection may be incorporated into an appropriately engineered setup, and the throttle body adapter includes a 1/8" NPT provision which can assist with such installations.

However, water-methanol injection should not be treated as a substitute for correct engineering, monitoring and ECU calibration.

Supercharger Bypass Valve

A bypass valve is included as part of the conversion.

The bypass system is an important part of a positive-displacement supercharger installation, allowing airflow to bypass the compressor under appropriate operating conditions rather than continually forcing the supercharger to operate against a closed or heavily restricted throttle.

Correct installation and operation of the bypass system should be confirmed before the vehicle is driven.

NOT Included

The following components are NOT included:

• M24 Supercharger Unit
• Engine Management / ECU
• Fuel Injectors

Additional components may also be required depending on the specification of the individual vehicle and engine.

⚠️ Engine Management & Mapping Required

DO NOT ATTEMPT TO RUN THE ENGINE UNDER BOOST ON THE FACTORY CALIBRATION UNLESS IT HAS BEEN SPECIFICALLY CALIBRATED FOR THE CONVERSION.

Adding a supercharger dramatically changes the quantity of air entering the engine.

Suitable engine management, fuel delivery and professional calibration are therefore essential.

The complete setup should account for:

• Fuel Injector Capacity
• Fuel Pressure
• Fuel Pump Capacity
• Intake Air Temperature
• Boost Pressure
• Ignition Timing
• Air/Fuel Ratio
• Engine Speed
• Engine Protection Strategies
• Supercharger Speed

Professional ECU calibration by an experienced tuner is required before the vehicle is operated under significant load.

Engine Condition

Forced induction places additional cylinder pressure and thermal load on the engine.

Before carrying out the conversion, we strongly recommend confirming the basic health of the engine.

Depending on the vehicle, this may include:

• Compression Testing
• Leak-Down Testing
• Cooling System Inspection
• Oil Pressure Checks
• Ignition System Inspection
• Fuel System Inspection
• Checking for Existing Oil Consumption or Blow-By

A supercharger cannot compensate for an unhealthy engine.

Belt Alignment & Installation

Particular attention must be paid to the supercharger drive system during installation.

Correct:

• Pulley Alignment
• Belt Tracking
• Belt Tension
• Idler Alignment
• Fastener Torque
• Component Clearance

must be confirmed before operation.

The belt should run centrally and consistently across the pulleys without attempting to walk off the drive system.

The installation should be inspected again after its initial running period.

What's Required to Complete the Conversion?

At minimum, customers should plan around sourcing and configuring:

• Suitable M24 Supercharger
• Appropriate Engine Management
• Suitable Fuel Injectors
• Professional ECU Calibration

Depending on the specification of the individual build, additional fuel system, sensor, electrical or supporting modifications may also be required.

No specific horsepower or boost pressure is guaranteed.

Final performance will depend on the engine specification, pulley selection, supercharger condition, intake temperature, fuel system, exhaust system and ECU calibration.

Motorsport & Modified Vehicle Notice

This is a significant forced-induction modification to the vehicle.

The customer is responsible for ensuring that the completed conversion complies with any applicable emissions, inspection, insurance and road-use requirements within their jurisdiction.

Professional installation is strongly recommended.
