This hybrid turbo for, designed for the 2.8 TD engine, is available in three documented tuning levels.. Its dimensions plug & play allow for Installation without modification, whilst its internal components are adapted according to the chosen tuning stage.
It is designed for the Mitsubishi Pajero II fitted with the 125 hp 4M40-T diesel engine, for during the installation period specified below.
Available versions — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust system: 360° bearing thrust
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR bench
This modification primarily affects the compressor impeller in order d to adjust the compression capacity and the air flow rate d. The 360° thrust bearing helps to distribute the rotor’s axial forces more evenly.
Stage 2
Compressor impeller: MFS high-flow oversized
d' intake housing: re-profiled for accommodate the new impeller oversized
Bearing system: 360° bearing
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR test bench
The Stage 2 combines a oversized compressor impeller with a d intake housing, re-profiled. This modification is designed to accommodate the new geometry and to alter the compressor’s air displacement capacity d.
Stage 3
Compressor impeller: MFS high-flow oversized
d intake housing: re-profiled for to accommodate the new impeller oversized
Thrust bearing system: 360° thrust bearing
Turbine impeller: high-flow oversized
Turbine casing: re-profiled for ly to accommodate the new impeller oversized
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR test bench
This configuration includes modifications to both the compressor and turbine sides. Increasing the size of the impellers can affect both flow rate and response time; the final performance depends on the overall engine set-up.
What is a hybrid turbo?
A hybrid turbo utilises a turbocharger architecture adapted for accommodate modified internal components. Depending on the stage, the modification may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing system and balancing.
The aim is d to adapt the compression capacity and air flow rate d. A hybrid turbo is not defined solely by the appearance of its impeller: the geometry of the components and their mechanical adaptation are crucial.
MFS compressor wheel: standard or Performance?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone does not guarantee an increase in air flow rate d. A standard MFS wheel may retain a geometry equivalent to that d of the original.
An MFS wheel Performance may utilise a geometry tailored to the tuning objective, for example a different profile or diameter. For this product, the wheel is described as lighter, larger and taller than the d original; the technical data sheet indicates an additional compression capacity of 15 per cent.
A standard MFS impeller can be just as efficient 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 flow rate can only be utilised properly with appropriate engine tuning.
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 blade arrangement influence its aerodynamic behaviour. A suitable geometry can move more d air under certain conditions, but the result also depends on the casings, the turbine, the boost pressure and the mapping. A larger impeller therefore does not automatically guarantee better performance across all ranges d'use.
Reliability and balancing of the hybrid turbo
The 360° thrust bearing distributes axial forces over a wide surface area. Each documented stage also benefits from d'high-speed balancing at 150,000 rpm on a Cimat VSR test bench, designed to limit vibrations and mechanical stresses on the rotor. However, this balancing does not protect the turbocharger against incorrect installation, inadequate lubrication or the presence d'of a foreign object.
Engine remapping and preparation
Appropriate engine management is required for to make the most of the hybrid turbo’s characteristics. The mapping, boost pressure, fuel injection, exhaust and cooling must be checked or adjusted according to the level of tuning. The wastegate must be adjusted when remapping the ECU. The clutch, transmission and other vehicle components must also be checked in accordance with the configuration.

Fitting instructions
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Carefully check the lubrication circuit, as well as the oil supply and return lines d. Check that the lines are clean, the inlet and that there are no foreign objects present. Carry out priming in accordance with the applicable recommendations and follow the manufacturer’s instructions.
Failure to rectify a lubrication fault may result in the turbocharger failing again.
How do you identify the correct turbo?
Check the part number marked on the original turbo d, then compare the OEM and manufacturer part numbers.. Also check the make, model, generation, body style, engine type, power output (125 hp), production period and engine code (4M40-T. ). An identical engine type is not always sufficient to confirm compatibility.
⚠️ 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 specification sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, please contact us with the part number clearly visible on your turbocharger.
