This hybrid turbocharger for, designed for the Bmw 3.0D engine, is available in three performance levels.. The documented modifications include an MFS compressor wheel Performance, a 360° bearing stop and high-speed balancing on a Cimat VSR test bench.
The specified applications include, in particular, the Bmw Series 3 E46 and X5 E53 in the 3.0 TD version from 183 hp. Installation is intended without modification d’turbo adaptation, subject to precise verification of the original part numbers d.
This set-up uses an MFS Performance impeller, the dimensions and configuration of which are suited to a higher air flow rate d. However, the final performance depends on the engine management system and the overall mechanical configuration.
Stage 2 combines a larger-diameter impeller with a reprofiled intake casing d. This modification is designed to adapt the air passage dto the new impeller and may affect the flow rate as well as the turbocharger’s response time.
This version features the largest compressor wheel documented for this product, with a reprofiled intake casing d. Its operation requires a suitable engine configuration and does not, on its own, guarantee a specific power output.
A hybrid turbo retains a turbocharger architecture designed for to accommodate modified internal components. Depending on the modification, changes may involve the compressor wheel, its dimensions, the geometry of the blades, the housings, the turbine wheel, the thrust bearing system or the balancing.
The aim is dto adapt the compression capacity and air flow rate d. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel, but by the consistency of its mechanical characteristics.
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 may retain a geometry equivalent to that of the doriginal.
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. An Performance impeller can utilise a diameter, profile or blade arrangement suited to the tuning objective. A higher airflow can help to generate more power, but only with appropriate engine tuning.
The compressor impeller draws in and then compresses the air intended for the engine. Its diameter, profile, height, width and blade arrangement influence its aerodynamic behaviour. A suitable geometry can move more dair under certain conditions, but the result also depends on the housing, the turbine wheel, the boost pressure and the engine tuning. A larger wheel does not automatically guarantee better performance and may alter the response time.
All three stages fea da 360° bearing stop, designed to distribute axial forces more evenly. The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench to minimise vibrations and mechanical stresses. However, this balancing does not compensate for incorrect installation or inadequate lubrication.
Adjustments to the mapping and boost pressure management may be necessary for to make the most of the hybrid turbo’s characteristics. Depending on the level of tuning, the injection system, fuel supply, air cooling d, intake, exhaust, clutch or transmission must also be checked. The wastegate must be adjusted during the fitting and remapping of the ECU.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. 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 priming in accordance with the applicable recommendations and follow the manufacturer’s instructions. Also adjust the wastegate during fitting and reprogramming. An unresolved lubrication fault may lead to further turbocharger failure.
Check the part number engraved on the turbo d, the original OEM and manufacturer part numbers, as well as the model, generation, engine type, power output,Year and engine code. An identical engine type does not always guarantee compatibility between two turbochargers.
⚠️ 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 in doubt, please contact us with the full 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.
