This hybrid turbo, designed for the following engines Mitsubishi 2.5 TD from 99 hp, features d' an internal modification aimed at adapting the air flow d. Depending on the upgrade package chosen, this combines a high-flow MFS compressor wheel, a 360° bearing stop and additional modifications to the casings or the turbine section.
Its ‘ plug & play ’ type assembly is documented at for for several versions of the L200 Mitsubishi, Montero Sport and Pajero 2 from 1997 onwards. The choice of upgrade must take into account the engine configuration and intended use.
Available tuning options — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Bearing retainer: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This kit acts primarily on the compressor section in order d to adjust the compression capacity and the air flow rate d. Its operation depends on the engine configuration and the associated settings.
Stage 2
Compressor impeller: MFS high-flow oversized
d intake housing: re-profiled for accommodate the new impeller oversized
Bearing thrust: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
d ’s intake casing is adapted to the oversized compressor wheel. This modification may alter the air flow rate d and the compressor’s performance, though it does not in itself guarantee a power gain.
Stage 3
Compressor impeller: MFS high-flow oversized
d'intake housing: re-profiled for to accommodate the new impeller oversized
Bearing thrust ring: 360°
Turbine impeller: high-flow oversized
Turbine casing: re-profiled for ly to accommodate the new impeller oversized
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This configuration modifies the compressor and turbine sides. The increase in impeller size can affect flow rate, operating range and response time; it must therefore be accompanied by appropriate modifications.
What is a hybrid turbocharger?
A hybrid turbo retains an architecture suited to the intended installation whilst incorporating internal modifications. Depending on the stage, these may involve the compressor impeller, the housings, the turbine impeller, the thrust bearing or the rotor balancing.
The aim is d to adapt the compression capacity and the air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its impeller: the geometry of the components and how they are combined determine its behaviour.
MFS compressor wheel: standard or Performance?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This is d'a manufacturing process which, on its own, does not guarantee an increase in air flow rate d'air. A standard MFS wheel may retain a geometry equivalent to that d'of the original.
The MFS Performance turbine documented here is a forged aluminium turbine, which is lighter, larger and taller than the d'original. The technical data sheet indicates an additional compression capacity of 15 per cent. Its actual efficiency depends on the overall configuration of the turbocharger and the engine.
A standard MFS impeller can be just as effective 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 help to generate more power when the engine is suitably tuned.
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 its aerodynamic behaviour and the amount d of air it can move under certain conditions.
The result also depends on the casings, the turbine wheel, the boost pressure and the engine set-up. 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 360° bearing thrust ring, present on all three stages, helps to distribute axial forces around the shaft. However, it does not protect the turbocharger against a lack of lubrication, contamination or incorrect installation.
The rotor is balanced at high speed, at 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses during rotation.
Engine remapping and preparation
The engine management system must be adapted for to make full use of the hybrid turbo’s characteristics. The mapping, injection, exhaust, cooling and boost pressure management must be checked or adjusted depending on the level of tuning. The wastegate must be adjusted whilst remapping the ECU. The clutch, the gearbox and other vehicle components may also require checking.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Before installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return d as well as the cleanliness of all pipes.
Check the inlet and ensure that no foreign objects can reach the compressor. Carry out priming in accordance with the applicable recommendations and follow the vehicle 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 and compare it with the OEM and manufacturer part numbers in this data sheet. Also check the make, model, generation, body style, engine type 2.5 TD, power output 99 hp,Year, and the engine code where available.
An identical engine specification is not always sufficient to confirm compatibility: there may be several different configurations depending on the vehicle version.
⚠️ Check your turbo’s part numbers
Before ordering, compare the part number marked on your original d turbo with the part numbers listed in this data sheet. An identical engine specification does not always guarantee compatibility.
If you are unsure about your fitment, please contact us with the part number clearly visible on your original turbo d.
