This hybrid turbocharger, designed for the following engines: 1.4 HDi, 1.4 TDCi and 1.4 D, features internal modifications tailored to the selected package.. The documented configurations combine a high-flow MFS compressor wheel, a 360° bearing stop and high-speed balancing.
Applications include, in particular, the Citroën, Ford, Peugeot and Toyota models producing 54 or 68 hp. Compatibility must always be confirmed using the original turbo part number d.
This configuration focuses on adapting the compressor impeller to alter the compression capacity and air flow rate d, whilst retaining the other documented characteristics of the Stage 1.
The Stage 2 combines a oversized compressor wheel with a reprofiled d intake housing. This modification is designed to ensure the correct fit and operation of the new wheel, with performance depending on the engine preparation and operating conditions d.
This configuration includes modifications to both the compressor and turbine sides. The sizing of the impellers and the re-profiling of the housings influence both the flow rate and the response of the turbocharger; the result depends on the overall engine configuration.
A hybrid turbo is based on a turbocharger architecture adapted for accommodate modified internal components. Depending on the stage, the modification may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system and balancing.
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 geometry, the adaptation of the housings and the overall coherence of the assembly are crucial.
MFS stands for ‘Milled From Solid’: the impeller is machined from a solid block. For this product, the compressor impeller is specified as forged aluminium and its configuration Performance is lighter, larger and taller than the original d.
A standard MFS impeller can retain a geometry equivalent to the original. An MFS impeller Performance features a geometry tailored to the tuning objective and can therefore alter the volume d of air displaced.
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. A higher airflow rate can contribute to power output with a suitably tuned engine, though this alone does not guarantee a specific 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 and the amount d of air it can move under certain conditions.
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 therefore does not automatically guarantee a better result and may alter the response time as well as the range d of optimal operation.
The 360° bearing thrust ring helps to distribute axial forces around the shaft. Here, it complements the documented internal modifications, without making the turbocharger immune to a lack of lubrication or incorrect installation.
The rotor is balanced at high speed, at 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses during operation.
The engine management system must be adapted for to make full use of the hybrid turbo’s characteristics. The wastegate must be adjusted during the ECU reprogramming.
Depending on the level of tuning, the fuel injection, boost pressure, exhaust system, cooling, intake and transmission must be checked or adjusted. Fitting d a hybrid turbo does not automatically guarantee a performance gain without a coherent set-up.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d installing the turbocharger.
dCheck the lubrication system, the oil supply and return lines, and ensure the pipes are clean. Also check the intake for any foreign objects.
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 lead to the turbocharger failing again.
Check the part number engraved or marked on the original turbo d, then compare the OEM and manufacturer part numbers.. Also check the make, model, generation, engine type, power output at hp, theYear and, where available, the engine code.
The same engine type may be fitted with several different turbochargers depending on the vehicle version.
⚠️ 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 part number clearly visible on your original turbocharger d.

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.
