This hybrid turbocharger for for the Toyota 2.4D engine is available in three performance levels.. Each stage combines an MFS compressor wheel Performance with precisely defined specifications, featuring a 360° bearing stop and high-speed balancing.
The documented applications cover the Toyota 4-RUNNER and LANDCRUISER 2.4 TD 90 from 1984 onwards. Installation is designed to require no modifications, provided the appropriate kit is selected and d the necessary adjustments are made.
Available configurations — Stage 1, Stage 2 and Stage 2+
Stage 1
Compressor wheel: MFS high-flow Performance
Dimensions: 36.10 / 57.00 mm
Blade configuration: 5+5
Bearing stop: 360°
Balancing: High-speed at 150,000 rpm on a Cimat VSR test bench
This set-up utilises an MFS Performance compressor wheel designed to adapt the air flow rate d whilst maintaining a documented Installation without modification performance. Its final performance depends on the engine’s configuration and settings.
Stage 2
Compressor wheel: MFS high-flow oversized Performance
Dimensions: 42.12 / 64.89 mm
Blade configuration: 6+6
Housing d Inlet: Reprofiled for to accommodate the new impeller oversized
Bearing stop: 360°
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
The Stage 2 features a larger-diameter impeller and a reprofiled intake housing d. These modifications may increase the air flow capacity d, but may also alter the turbocharger’s response depending on the settings and associated equipment.
Stage 2+
Compressor wheel: MFS high-flow oversized Performance
Dimensions: 49.70 / 67.40 mm
Blade configuration: 6+6
d intake housing: Reprofiled for commodate the new impeller oversized
Bearing stop: 360°
Balancing: High-speed at 150,000 rpm on a Cimat VSR test bench
This version uses a specific oversized compressor impeller and an intake d housing adapted to its dimensions.. This choice is intended to achieve a different flow capacity, though it does not in itself guarantee a specific final power output or improved performance in all conditions.
What is a hybrid turbo?
A hybrid turbo is based on a turbocharger design adapted for to accommodate internal components that differ from the original configuration d. Depending on the stage of the upgrade, the modifications may involve the compressor wheel, its dimensions, the geometry of the blades, the machining of the housing, the thrust bearing or the balancing.
The aim is d'to adapt the compression capacity and air flow d'to the requirements of the engine tuning. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel: the dimensions, geometry and overall consistency of the unit are crucial.
MFS compressor wheel: standard or ‘ Performance ’?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This term describes its manufacturing process, but does not in itself guarantee an increase in air flow d.
A standard MFS impeller may retain a geometry equivalent to that of the ori d. An MFS Performance impeller may feature a geometry, diameter, profile or blade configuration tailored to the purpose of the modification.
A standard MFS impeller can be just as shiny as an MFS impeller Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d air. A higher airflow rate can help to generate more power with the appropriate engine tuning, though it does not in itself guarantee a power gain.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and the arrangement of its blades influence the compressor’s aerodynamic behaviour.
The right geometry can move more air d under certain conditions. The result also depends on the casings, the turbine wheel, the boost pressure and the engine tuning. A larger wheel does not automatically guarantee better performance and may alter the response time as well as the range d of optimal operation.
Reliability and balancing of the hybrid turbo
The three documented tuning stages feature d a 360° bearing stop, designed for to distribute axial forces over a wider surface area. This feature does not eliminate the need d for proper lubrication or d for correct installation.
Each unit undergoes d high-speed balancing at 150,000 rpm on a Cimat VSR test bench. Rotor balancing helps to limit vibrations and mechanical stresses, but does not protect against inadequate lubrication, contamination or incorrect installation.
Engine remapping and preparation
To make the most of the characteristics d of a hybrid turbo, the engine management system and boost pressure must be adapted to the configuration. The wastegate must be adjusted during the fitting and remapping of the ECU.
Depending on the level of tuning, it is also advisable to check or d'adjust the fuel injection, exhaust, cooling, intake and, if necessary, the transmission. Fitting the hybrid turbo does not automatically guarantee a power gain without appropriate tuning.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d installing the turbocharger. Check the lubrication system, the oil supply and return d as well as the cleanliness of all pipes.
Check the intake for foreign objects. Prime the system in accordance with the applicable recommendations and follow the manufacturer’s instructions. The wastegate and engine management system must be adjusted according to the chosen set-up.
Unresolved lubrication issues may lead to further turbocharger failure.
How do you identify the correct turbo?
Check the part number marked on the original turbo d and compare it with the manufacturer’s part numbers in this data sheet. Also check the make, model, engine type, power output at hp, theYear and the engine code where available. An identical engine type may have several different configurations.
⚠️ Check your turbo’s part numbers
Before ordering, compare the part number marked on your original turbo d with the part numbers listed in this data sheet.. An identical engine specification does not always guarantee compatibility.
If in doubt, contact our team with the part number clearly visible on your original turbocharger d.
