This hybrid turbo for Mercedes -Benz Sprinter 2.2 CDI undergoes internal modification designed to adjust its compression capacity and air flow rate d. Depending on the upgrade package chosen, this includes a high-flow MFS compressor wheel, recontouring of the housings and, at the most advanced level, a turbine wheel oversized.
Documented applications cover several Sprinter variants with power outputs of 108, 109 or 129 hp. Compatibility must always be confirmed using the original turbocharger part number d.
Available tuning options — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrustbearing: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This tuning programme primarily affects the compressor section. The MFS impeller is designed for to adjust the compression and displacement dof the air, although a specific power gain cannot be guaranteed regardless of the engine tuning.
Stage 2
Compressor impeller: MFS high-flow oversized
Intake housing d: re-profiled for accommodate the new impeller
Stop: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
The Stage 2 combines a oversized compressor impeller with a reprofiled dintake housing. This modification is designed to correctly accommodate the new geometry and to increase the compressor’s air flow rate d.
Stage 3
Compressor impeller: MFS high-flow oversized
dintake housing: re-profiled for to accommodate the new impeller
Thrustbearing: 360°
Turbine impeller: high flow oversized
Turbine housing: re-profiled for ly to accommodate the new impeller
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
Stage 3 is fitted on both the compressor and turbine sides. The final performance depends on the engine assembly, boost pressure and the settings applied; this level is therefore not automatically the most suitable for every configuration.
What is a hybrid turbo?
A hybrid turbo retains a turbocharger architecture adapted to accommodate modified internal components. Depending on the stage of the upgrade, the modifications may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing and the balancing of the rotor.
The aim is dto adapt the compression capacity and the air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: its geometry, the adaptation of the housings and the overall coherence of the assembly 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 airflow. A standard MFS wheel can retain a geometry equivalent to that of the d’original.
An MFS wheel Performance can be given a geometry tailored to the intended use. On this product, the wheel is described as lighter, larger and taller than the original d, with a claimed 15 per cent higher compression capacity. 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.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air admitted by the engine. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour. A suitable geometry can move more d’air under certain conditions, but the result also depends on the housings, the turbine, the boost pressure and the engine management system. A larger impeller can also alter the response time and the range dof optimal operation.
Reliability and balancing of the hybrid turbo
The 360° thrust bearing, documented across the three stages, distributes the axial forces around the shaft. The rotor is balanced at high speeds, up to 150,000 rpm, on a Cimat VSR test bench to minimise vibrations and mechanical stresses. This balancing does not compensate for inadequate lubrication, contamination or incorrect installation.
Engine remapping and preparation
Appropriate engine management is required for to make the most of the hybrid turbo’s characteristics. The mapping, boost pressure and wastegate settings must be checked. Depending on the configuration, the fuel injection, exhaust, cooling, intake and transmission may also require checking or adjustment. The turbo alone does not guarantee a power gain.

Fitting advice
⚠️ 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 d. Check that the pipes are clean, the inlet and that there are no foreign objects. Carry out the priming procedure in accordance with the applicable recommendations and follow the manufacturer’s instructions. The wastegate must be adjusted when adapting the engine management system. An uncorrected lubrication fault may lead to further turbocharger failure.
How do you identify the correct turbo?
Check the part number marked on the turbo dthe original, OEM and manufacturer part numbers, as well as the model, generation, body style, engine type, power output,Year and engine code. An identical engine may be fitted with several different turbocharger 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 does not always guarantee compatibility.
If in doubt, please contact us with the full part number taken from your turbocharger.
