This hybrid turbo for engine variants 1.3 MJTD and 1.3 CDTI models with 85 or 90 hp is available in several levels of mechanical preparation. Depending on the upgrade package chosen, the modifications relate to the high-flow MFS compressor wheel, the casings, the bearing thrust ring and, for the most advanced stage of production: the turbine section.
The documented applications include, amongst others, several models Alfa Romeo, , Fiat, , Lancia and Opel. The design is planned for an installation plug & play, without any changes to the layout d'origin'.
This product acts primarily on the compressor section in order to d'adjust the flow rate' d'air'. The 360° thrust bearing helps to distribute axial forces more evenly within the turbocharger.
The Stage 2 incorporates a compressor wheel oversized to a casing d're-profiled intake'. The aim of the whole process is to adapt the airflow and compression to the new geometry, without prejudging the final result, which depends on the engine configuration.
This modification affects the compressor and turbine sides. Reprofiling the two casings allows d'to accommodate the corresponding oversized wheels'. This configuration may affect the flow rate d'air, the turbo’s performance and its response time; utilising it requires appropriate engine tuning.
A hybrid turbo is based on a specially adapted turbocharger design for to receive internal components or machined parts that differ from the specification d'origin'. Depending on the course, the modifications may relate to the compressor impeller, its dimensions, the casings, the turbine impeller, the thrust bearing or the balancing.
The aim is d'adjust the compression capacity and flow rate' d'air to meet the requirements of the preparation'. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the consistency between the wheels, the housings, the balancing and the engine management system remains crucial.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This designation describes the manufacturing process, but does not in itself guarantee an increase in flow rate d'air'. A standard MFS wheel can retain a geometry equivalent to the original.
An MFS wheel Performance can be designed with a geometry suited to the intended application, with a specific profile or dimensions where such modifications are required. For this product, the wheels are described as high-flow, and, for Stages 2 and 3, oversized.
A standard MFS wheel can be just as shiny as an MFS wheel Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d'air'. A higher flow rate can help to increase power output with the appropriate engine tuning, although this alone does not guarantee results.
The compressor wheel draws in and then compresses the air fed to the engine. Its diameter, profile, height, width and the arrangement of its blades influence the aerodynamic behaviour of the compressor. The right geometry can move more d'air under certain operating conditions'.
The result also depends on the casings, the turbine wheel, the boost pressure and the engine tuning. A larger wheel therefore does not automatically guarantee better handling and may affect the response time as well as the range d'optimal use'.
The three work placements offer d'a 360° bearing stop, designed for distribute axial forces over a suitable surface. This feature does not exempt one from d'proper lubrication or compliance with the installation requirements'.
The assembly is balanced at high speeds, up to 150,000 rpm, on a Cimat VSR test bench. This procedure is designed to minimise vibrations and stresses on the rotor, but does not protect the turbocharger against contamination or faults d'oil or incorrect installation'.
The mapping and management of boost pressure need to be adjusted for make proper use of the features d'a hybrid turbo'. The wastegate must be adjusted when the ECU is remapped.
Depending on the level of preparation: fuel injection, exhaust, air cooling d'The intake, clutch or gearbox must also be checked and, if necessary, adjusted'. The editing d'A hybrid turbo does not automatically guarantee a power boost without appropriate engine tuning'.
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Search for and correct the cause of the previous failure before d'fit the turbo'.
Check the lubrication circuit, the supply and the return d'oil'. Check that the ducts and the intake are clean and free from foreign objects.
Carry out turbocharger spool-up in accordance with the relevant guidelines and follow the vehicle manufacturer’s instructions.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
Check the part number on the turbocharger d'origin and compare it with the OEM and manufacturer part numbers listed on this sheet'. Also check the make, model, generation, body style, engine type and power output in hp, theYear the mounting code and the engine code, where available.
The same engine can be fitted with several different turbocharger set-ups. The reference number marked on the coin d'Origin' therefore remains the primary basis for comparison.
⚠️ Check your turbo’s part numbers
Before placing your order, Compare the part number on your turbocharger d'origin' using the references given in this fact sheet. Having the same motor does not always guarantee compatibility.
If you’re unsure, please contact us with the reference number clearly visible on your turbo d'origin'.

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.
