This hybrid turbocharger for, designed for the 1.9 JTD engine, is available in three performance levels.. Each version features an MFS compressor wheel Performance and a 360° bearing retainer, with high-speed balancing carried out at 150,000 rpm on a Cimat VSR test bench.
Documented applications include the Alfa Romeo, 159 and 159 Sportwagon, as well as the Fiat Croma, in the 136 and 150 hp diesel versions listed below.
This set-up is based on an MFS Performance impeller with a higher flow rate. Its geometry is designed to match the compression capacity and air displacement d without any documented housing modifications for this workshop.
dThe larger impeller diameter requires the intake casing to be re-profiled. This combination can increase flow capacity, but may also alter the turbocharger’s response depending on the engine’s settings and configuration.
This version features the largest compressor impeller amongst the documented. set-ups. Its use requires a suitable engine configuration; a larger-diameter impeller is not automatically preferable in all conditions d use.
A hybrid turbo retains a turbocharger architecture adapted to accommodate modified internal components. Depending on the modification, changes may relate to the compressor wheel, its geometry, its dimensions, the machining of the housings, the thrust bearing or the balancing.
The aim is d to adapt the compression capacity and air flow rate d to a specific engine modification. 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 manufacturing process alone does not guarantee an increase in d'air flow. A standard MFS wheel may retain a geometry equivalent to that d'of the original.
An MFS impeller Performance can have a diameter, profile or blade configuration tailored to the tuning objective. For this product, dimensions and configurations vary depending on the tuning package selected.
A standard MFS impeller can be just as effective as a Performance MFS impeller. It is not its appearance that determines its performance, but its geometry and its ability to move more d air. A higher airflow can contribute to power output when the engine tuning is correctly adapted.
The compressor impeller draws in and then compresses the air intended for the engine. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour and the amount d of air displaced under certain operating conditions.
The result also depends on the compressor housing, the turbine section, the boost pressure and the engine set-up. An increase in diameter can alter the response time and the range d of optimal operation.
The 360° bearing thrust stop, documented across the three stages, helps to distribute axial forces. It does not replace d'proper lubrication or d'correct installation.
Rotor balancing limits vibrations and mechanical stresses at high speeds. Each preparation presented is balanced at 150,000 rpm on a Cimat VSR test bench. This balancing does not protect the turbocharger against faults d such as oil issues, contamination or incorrect installation.
The engine management system must be adapted for to make the most of the hybrid turbo’s characteristics. This involves mapping, boost pressure, injection, intake air cooling d, the exhaust system and, depending on the vehicle, the clutch or gearbox must be checked. The wastegate must be adjusted during fitting and when remapping the ECU. The turbo alone does not guarantee any power gain.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Before installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return d, the cleanliness of the pipes, the inlet and the absence of foreign objects. Carry out the priming procedure in accordance with the applicable recommendations and follow the manufacturer’s instructions. Wastegate adjustment and mapping must be carried out by a qualified professional. An uncorrected lubrication fault may result in further turbocharger failure.
Check the part number marked on the turbo d, the original OEM and manufacturer part numbers, as well as the make, model, generation, body style, engine type, power output, years of manufacture and engine code.. An identical engine may be fitted with several different turbo set-ups.
⚠️ 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 your turbo’s full part number.

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.
