This hybrid turbo for for the Mitsubishi 2.5 TDID engine, with power outputs ranging from 133 to 136 hp, has undergone internal modifications designed to adjust its compression capacity and air flow rate d. . Depending on the upgrade package chosen, the configuration includes a high-flow MFS compressor impeller, a 360° thrust bearing and various casing reprofiling works.
It is designed for the following applications: Mitsubishi L200, L300, L400 and Pajero models from 2005 onwards. It is designed to be fitted without modifying the original mounting d, provided the turbocharger part numbers are checked carefully.
Available versions — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing system: 360° thrust bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
This modification affects the compressor section in order dto adapt the air flow rate dwhilst retaining the casings documented for for this configuration.
Stage 2
Compressor impeller: MFS high-flow oversized
Compressor housing: Reprofiled for accommodate the new impeller oversized
Thrust bearing system: 360° thrust bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
Reprofiling the housing allows th dto adapt its passage to the compressor wheel oversized. This modification may alter the air flow rate dand the turbo’s behaviour depending on the mapping and the overall engine configuration.
Stage 3
Compressor wheel: MFS high-flow oversized
Compressor housing: Reprofiled for to accommodate the new impeller oversized
Bearing system: 360° thrust bearing
Turbine impeller: High-flow oversized
Turbine housing: Reprofiled for ly to accommodate the new impeller oversized
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
This configuration combines modifications to both the compressor and turbine sides. Its performance depends on the balance between air flow d, turbo response, boost pressure and engine settings.
What is a hybrid turbo?
dA hybrid turbo is based on a turbocharger architecture adapted for accommodate internal components that differ from the original configuration. Depending on the stage, the modification may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system and rotor balancing.
The aim is dto adjust the compression capacity and the air flow rate d. However, the appearance dof an impeller is not sufficient to define the performance dof a hybrid turbo: the geometry of the components, their combination and the engine tuning are decisive.
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 d. A standard MFS wheel can retain a geometry equivalent to that dof the original.
An MFS wheel Performance can be given a geometry tailored to the tuning objective. For this product, the wheel is described as lighter, larger and taller than the d’original; the available data indicate an additional compression capacity of 15 per cent.
A standard MFS impeller can perform just as well 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 can only be fully utilised 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 dair under certain conditions, but the result also depends on the housings, the turbine, the boost pressure and the mapping. A larger impeller can also alter the response time and the range dof optimal operation.
Reliability and balancing of the hybrid turbo
The documented 360° bearing stop helps to distribute axial forces around the shaft. It does not replace d’the need for proper lubrication or compliance with installation requirements.
The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This balancing is designed to minimise vibrations and mechanical stresses, but does not protect the turbocharger against a lack d’oil, contamination or incorrect installation.
Engine remapping and preparation
The engine mapping must be adjusted for to make full use of the hybrid turbo’s characteristics. Boost pressure, injection, exhaust, cooling and, depending on the vehicle, the transmission must be checked or adjusted. The wastegate must be adjusted when remapping the ECU. Simply fitting da hybrid turbo does not, on its own, guarantee a power gain.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous failure. Check the lubrication circuit, as well as the oil supply and return d. Check that the pipes and inlet are clean and free from foreign objects.
Prime the system in accordance with the applicable recommendations and follow the manufacturer’s instructions. A lubrication fault that is not rectified may lead to further turbocharger failure.
How do you identify the correct turbo?
Check the part number marked on the original turbo dand compare it with the manufacturer’s part numbers and the other part numbers listed in this data sheet. Also check the model, engine type, power output, production period and engine code where available. An identical engine type does not always guarantee 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 product sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, please contact us with the full part number taken from your turbocharger.
