This hybrid turbo, designed for the 2.and 2 CDI engines with 115 and 141 hp, is available in three performance levels. Its design is tailored to each performance level to doptimise air flow d, featuring a high-flow MFS compressor wheel and documented mechanical modifications.
Installation is advertised as plug & play, requiring no external modifications. However, the configuration of the engine and its peripherals must be adapted to the chosen trim level.
Available tuning packages — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing: 360° bearing
Balancing: high-speed at 150,000 revolutions per minute on a Cimat VSR test bench
This modification affects the compressor section to d’adapt the air displacement capacity d’air, whilst retaining a configuration closer to the base design than the higher-specification stages.
Stage 2
Compressor impeller: MFS high-flow oversized
dIntake casing: re-profiled for accommodate the new impeller oversized
Thrust bearing: 360° bearing
Balancing: high-speed balancing at 150,000 revolutions per minute on a Cimat VSR test bench
oversized ’s compressor impeller requires the intake housing to be re-profiled d. This combination aims to increase flow capacity, although it cannot, on its own, guarantee a specific engine power output.
Stage 3
Compressor impeller: MFS high-flow oversized
Casing d’ intake: re-profiled for accommodate the new impeller oversized
Thrust bearing: 360° bearing
Turbine impeller: high flow oversized
Turbine casing: reprofiled for ly to accommodate the new impeller oversized
Balancing: high-speed balancing at 150,000 revolutions per minute on a Cimat VSR test bench
This modification alters both the compressor and turbine sides. The final performance depends on the overall engine configuration; in particular, a larger impeller may alter the response time and the range d’optimal operating conditions.
What is a hybrid turbocharger?
A hybrid turbo is based on a turbocharger architecture adapted for accommodate internal components that differ from the original configuration d. Depending on the upgrade, modifications may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing system and balancing.
The aim is dto adapt the compression capacity and air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the compatibility between the wheels, the housings and the engine tuning remains 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 airflow d’air. A standard MFS wheel may retain a geometry equivalent to that d’of the original.
An MFS impeller Performance can be given a geometry tailored to the tuning objective, in particular through its profile, the height or width of its blades and its diameter. On this product, higher-level tuning packages use a compressor impeller oversized with a re-profiled intake casing d.
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 flow rate can help to develop more power only when combined 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 destined for the engine. Its diameter, profile, height, width and blade arrangement influence its aerodynamic behaviour. A suitable geometry can move more dair under certain operating conditions.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine mapping. A larger impeller therefore does not automatically guarantee better performance in all conditions.
Reliability and balancing of the hybrid turbo
The 360° bearing stop, featured on all three stages, helps to distribute axial forces. It must operate with correct lubrication and does not make the turbocharger immune to incorrect installation or a fault din the oil supply.
Each unit undergoes dhigh-speed balancing at 150,000 revolutions per minute on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses on the rotor.
Engine remapping and tuning
The engine management system must be adapted for to make full use of the hybrid turbo’s characteristics. The mapping, boost pressure, fuel injection, exhaust and cooling systems must be checked and adjusted according to the vehicle and the level of tuning.
The wastegate must be adjusted during ECU remapping. The clutch, gearbox and other components may also require checking. Fitting the turbocharger alone does not guarantee any specific power gain.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d’installing the turbo. Check the lubrication circuit, the oil supply and return d’as well as the cleanliness of the pipes.
Check the intake for foreign objects. Prime the system in accordance with the applicable recommendations and follow the vehicle manufacturer’s instructions.
A lubrication fault that is not rectified may lead to further damage to the turbocharger.
How do you identify the correct turbo?
Check the part number engraved on the original turbo dand compare it with the OEM and manufacturer part numbers in this sheet. Also check the model, generation, body style, engine type 2.2 CDI, power output hp, theYear and the engine code where available.
The same engine may have been fitted with several different turbochargers depending on the version or production period.
⚠️ 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 does not always guarantee compatibility.
If in doubt, please contact us with the full part number taken from your original turbo d.
