This hybrid turbo is designed for several engine variants Mercedes 2.5 TD and 2.9 TD with 120 or 150 hp. Its specification combines a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing, with modifications tailored to the selected performance level.
The unit is designed for a ‘ plug & play ’ configuration, with no external modifications d'installation. The documented applications include, in particular, the Mercedes C250, E250, G290 and Sprinter.
This configuration enhances the compression capacity and air flow rate d thanks to the high-flow MFS impeller, whilst maintaining the mechanical characteristics documented for this stage.
The housing has been re-profiled to allow d to fit the impeller oversized. This modification is intended to alter the compressor’s air displacement capacity d, without affecting the engine’s final power output.
The documented specifications for for this variant include an MFS impeller oversized and a housing d with a reprofiled inlet. The choice of stage must take into account the engine’s overall configuration and intended use.
A hybrid turbo utilises a turbocharger architecture adapted for to accommodate modified internal components. Depending on the specification, modifications may involve the compressor wheel, its geometry, its dimensions, the housings, the turbine wheel, the thrust bearing or the balancing.
The aim is d to adapt the compression capacity and air flow rate d. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel: its performance depends on its entire mechanical configuration.
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 can retain a geometry equivalent to that d'of the original.
For this product, the high-flow MFS impeller is specified as being made of forged aluminium, lighter, larger and taller than the d'original' impeller. The product specifications indicate 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 help to generate more power when the engine is suitably tuned.
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 displaced under certain operating conditions.
The result also depends on the compressor housing, the turbine, its housing, the boost pressure and the engine set-up. A larger impeller does not automatically guarantee better performance and may alter the response time as well as the range d of optimal operation.
The documented 360° thrust bearing helps to distribute the axial forces to which the rotating assembly is subjected. However, it does not eliminate the need d for proper lubrication or d for correct installation.
The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses, without compensating for any installation faults d, contamination or insufficient oil supply.
The engine management system must be adapted for make full use of the hybrid turbo’s characteristics. The wastegate must be adjusted during the ECU reprogramming.
Depending on the configuration, it is also advisable to check or d'adjust the fuel injection, boost pressure, exhaust system, cooling system, intake system and, if necessary, the transmission. Fitting d'a hybrid 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 d, as well as the cleanliness of the pipes.
Check the inlet for foreign objects. Prime the system in accordance with the applicable guidelines and follow the vehicle manufacturer’s instructions.
Failure to rectify a lubrication fault may result in the turbocharger failing again.
Check the part number on the original turbo d and compare it with the OEM and manufacturer part numbers in this fact sheet. Also check the make, model, generation, engine type, power output at hp, theYear and the 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 data sheet. An identical engine specification does not always guarantee compatibility.
If you are unsure about the identification or fitment, please contact us before ordering.

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.
