This hybrid turbocharger is designed for 1-litre diesel engines.9 JTD/JTDM 90, 116 and 120 hp is available in three different preparation levels. Each course includes an MFS compressor wheel Performance with precisely defined characteristics, a 360° bearing stop and high-speed balancing.
The documented allocations relate to several models Alfa Romeo and Fiat. Compatibility must always be confirmed using the turbo’s part number dthe vehicle’s make, engine code and model.
This setup uses an MFS wheel Performance a higher flow rate. Its geometry is designed for adjust the travel capacity d’compressor air, without prejudging the engine’s final power output’.
The Stage 2 pairs a wheel oversized to re-profiling the casing d’admission’. This adaptation makes it possible to d…to accommodate the new geometry and may alter the flow rate d’air and the behaviour of the turbocharger.
The Stage The 2+ is fitted with a larger compressor wheel and a casing d’re-profiled intake’. This configuration is designed for a different flow capacity, but its performance depends on the overall engine set-up and the operating conditions dintended uses.
A hybrid turbocharger is based on a turbocharger design that has been adapted to accommodate internal components or machining processes that differ from the standard configuration d’origin’. Depending on the overhaul, modifications may include, amongst other things, the compressor wheel, its dimensions, the geometry of its blades and the re-profiling of the housing d’admission’.
The aim is d’adjust the compression capacity and flow rate’ dair. However, the result depends on the balance between the compressor, the turbine, the casings, the boost pressure and the engine management system. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel.
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 dair.
A standard MFS wheel can retain a geometry equivalent to that d’origin’. An MFS wheel Performance may, where the technical specifications so provide, adopt a diameter, profile or blade arrangement suited to the purpose of the preparation.
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 dair. A higher flow rate can help to generate more power when the engine has been properly tuned, although this does not in itself guarantee a performance gain.
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 its aerodynamic behaviour and its ability to move air across different operating ranges.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine tuning. A larger wheel does not automatically guarantee a better result and may affect the response time as well as the range doptimal use.
The three documented work placements include da 360° bearing stop, designed for distribute axial forces across the entire surface. This component contributes to the mechanical integrity of the turbocharger, without making it immune to faults arising from incorrect assembly, lubrication or adjustment.
The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. The aim of this operation is to minimise vibrations and mechanical stresses on the rotor during operation.
It may be necessary to adjust the engine management system for make the most of the hybrid turbo’s features. The wastegate must be adjusted during installation and when the ECU is reprogrammed.
Depending on the level of preparation, the mapping, the boost pressure, the fuel supply and the air cooling d’The intake, exhaust, clutch or transmission may need to be checked or adjusted’. The editing dA hybrid turbo does not automatically guarantee a power boost.
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Identify and rectify the cause of the previous fault before d’fit the turbocharger’.
Check the lubrication circuit, the supply and the return d’oil, as well as the cleanliness of all the pipes. Also check the intake and ensure there are no foreign objects present.
Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions. Adjusting the wastegate and modifying the engine management system must be carried out by a qualified professional.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
Check the part number marked on the turbocharger d…the original and compare it with the OEM and manufacturer’s specifications in this data sheet. Also check the make, model, generation, body style, engine type and power output in hp, the years of manufacture and the engine code. The same engine can be fitted with several different turbo set-ups.
⚠️ 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 dthe vehicle’s origin and specific details.

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.
