This for hybrid turbocharger for 2.5-litre diesel engines features internal modifications based on an MFS compressor wheel Performance, a 360° bearing stop and high-speed balancing.. Three levels of modification are documented to d adapt the turbocharger’s characteristics to the engine project.
The main applications are the Bmw 5 Series E39 with 163 hp and the Opel Omega B with 150 hp. Compatibility must always be confirmed using the original turbo part number d.
This configuration utilises an MFS Performance impeller designed for djust the air flow rate d whilst retaining a configuration intended for for direct mounting.
The increased diameter and reprofiling of the intake d housing allow d'accueillir la nouvelle roue and d'adapter la capacité de compression. The final performance depends on the engine configuration and its settings.
This version features the largest compressor wheel of the three documented set-ups. Its operation requires a suitable engine configuration and appropriate tuning; the final power output cannot be deduced from the wheel’s dimensions alone.
A hybrid turbo is based on a turbocharger architecture adapted for to accommodate modified internal components. Depending on the modification, these changes may relate to the compressor wheel, its dimensions and geometry, the machining of the casings, the thrust bearing or even the balancing of the rotor.
The aim is d to adapt the compression capacity and air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its impeller: its characteristics depend on the mechanical modification as a whole.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone does not guarantee an increase in air flow rate d. A standard MFS wheel can retain a geometry equivalent to that d of the original.
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 Performance geometry may utilise a profile, diameter or blade configuration suited to the tuning objective. A higher airflow rate can help to generate more power, but only with appropriate engine tuning.
The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and blade arrangement all influence its aerodynamic behaviour. Suitable geometry can move more d air under certain conditions, but the result also depends on the casings, the turbine, the boost pressure and the engine tuning. A larger impeller can also alter the response time and the d range of optimal operation.
The documented 360° thrust bearing distributes axial forces over a wide surface area. The rotor is balanced at high speeds, up to 150,000 rpm, on a Cimat VSR test bench to minimise vibrations and mechanical stresses. However, these characteristics do not compensate for inadequate lubrication or incorrect installation.
The operation d of a hybrid turbocharger may require adjustments to the mapping, boost pressure, fuel injection, and the cooling of the d intake air and exhaust. The clutch, the gearbox and other components must also be checked in accordance with the project. The wastegate must be adjusted during fitting and remapping. The turbo alone does not guarantee any power gain.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication system, the oil supply and return lines d, then check that the pipes and the inlet are clean and free from foreign objects.. Prime the system in accordance with the applicable recommendations and follow the manufacturer’s instructions.. A lubrication fault that is not rectified may lead to further turbocharger failure.
Check the part number of the original turbo d, the OEM and manufacturer part numbers, as well as the make, model, generation, body style, engine type, power output, production period and engine code. An identical engine type is not always sufficient to confirm 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 specification sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, contact our team with the part number from your turbocharger.

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.
