This hybrid turbocharger for the for, with a 2.2 CDI, is available in several performance levels.. Depending on the performance level selected, the modifications include the high-flow MFS compressor wheel, the housings, the turbine wheel, the bearing thrust ring and rotor balancing.
It is designed for the Mercedes-Benz V200, V220 and Vito 638 series, corresponding to the part numbers and applications listed below. Its design plug & play allows for Installation without modification of the vehicle.
This modification primarily affects the compressor section. The high-flow MFS impeller is designed to adjust the compression capacity and air flow rate dwhilst maintaining a ready-to-install configuration.
The Stage 2 combines a oversized compressor impeller with a reprofiled dintake casing. This mechanical adaptation enables dthe new geometry to be accommodated and can increase the air displacement capacity dunder suitable operating conditions.
Stage 3 modifies the compressor and turbine sides. The oversized impellers require the corresponding housings to be re-profiled. This configuration may alter the air flow rate d, the turbo’s behaviour and its response time; it must therefore be combined with appropriate engine tuning.
A hybrid turbo uses a turbocharger design adapted for to accommodate internal components that differ from the original configuration d. Depending on the stage, the modification may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing and balancing.
The aim is dto adapt the compression capacity and air flow dto the requirements of the engine tuning. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the wheels, their combination with the housings and the balance of the assembly as a whole are decisive factors.
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. A standard MFS wheel may retain a geometry equivalent to that dof the original.
An MFS wheel Performance has a geometry tailored to the tuning objective. On this product, the wheel shown is made of forged aluminium; it is 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 shiny 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 contribute to power output with the right engine tuning, though it does not, on its own, guarantee the final result.
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. A suitable geometry can move more dair within certain operating ranges.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine management system. A larger impeller does not automatically guarantee better performance and may alter the response time as well as the optimal operating conditions d.
The 360° bearing thrust ring, fitted to all three stages, helps to distribute the axial forces exerted on the rotating assembly. It does not eliminate the need dfor proper lubrication or compliance with installation requirements.
Each unit undergo dhigh-speed balancing at 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses on the rotor, though it cannot compensate for incorrect installation, contamination or a fault din the oil supply.
Appropriate engine management is required for to make the most of the characteristics dof a hybrid turbo. Map settings, boost pressure and wastegate adjustment must be checked when remapping the ECU.
d dDepending on the level of tuning, the injection, exhaust and cooling systems may also require checking or adjustment. The clutch, gearbox and other vehicle components must remain compatible with the intended operating conditions. Fitting the turbo alone does not guarantee a power increase.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Before installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return das well as the cleanliness of all pipes.
Check the intake and ensure there are no foreign objects present. Carry out the priming procedure in accordance with the applicable recommendations and follow the vehicle manufacturer’s instructions.
A lubrication fault that is not rectified may result in the turbocharger failing again.
Check the part number marked on the original turbo dand compare it with the OEM and manufacturer part numbers in this data sheet. Also check the make, model, generation 638, version, engine type 2.2 CDI, power output, production period and engine code where available. An identical engine specification does not always guarantee compatibility.
⚠️ Check your turbo’s part numbers
Before ordering, compare the part number marked on your original dturbocharger with the part numbers listed in this data sheet. An identical engine specification does not always guarantee compatibility.

A single engine type may have been fitted with several different turbochargers depending on theYear, power output, engine version or technical evolution.. The application alone is therefore not always sufficient for to accurately identify the correct turbo.
Before ordering, note down the part numbers shown on the identification plate d of your old turbocharger. This may be d an OEM part number or d a part number from the turbo manufacturer.
Compare these part numbers with those listed on our product pages.. If in doubt, our team can help you verify the part number you are looking for before you place your order.
A loss of power, an unusual whistling noise, oil consumption d, abnormal smoke or poor engine performance may be linked to a turbocharger fault.
However, a fault that appears to be turbo-related may also stem d from a lubrication issue, d from contaminated oil, d from a foreign object, from the intake or exhaust systems, or d from another engine peripheral component.
It is therefore important to investigate the cause of the fault before fitting a new turbo or a new Cartridge.
Since 2012, ALFI TURBO has been assisting private individuals and professionals in identifying and replacing turbochargers.
A turbocharger failure may be the result d of another engine problem. Before fitting d a new turbo or Cartridge, identify and rectify the cause of the original fault to d avoid d damaging the new part.
