This hybrid turbo for petrol engines 1.The 4 TB T-JET features an MFS compressor impeller Performance with a 360° bearing stop and high-speed balancing. Three documented levels of preparedness enable d'adjust the dimensions of the compressor wheel and, depending on the stage, the profile of the housing' d'admission'.
The allocations include, in particular, several Abarth 500, 595, 695 and Punto models, Alfa Romeo Giulietta and MiTo, Fiat 500X as well as Jeep Renegade. Compatibility must always be confirmed using the turbo’s part number d'origin'.
This setup uses an MFS wheel Performance designed for adjust the flow rate d'compressor air, whilst retaining the documented installation configuration'.
The wheel with the larger diameter comes with d're-profiling the casing' d'admission'. This arrangement is designed to adapt the air flow and compression to the dimensions of the new impeller.
This version features the largest compressor impeller documented on this data sheet and a casing d'adapted admission'. Its performance depends on the overall engine configuration and the settings selected.
A hybrid turbocharger utilises a turbocharger design that has been adapted to accommodate specific internal components. Depending on the modification, changes may relate to the compressor wheel, its dimensions, the geometry of the blades, the casings, the thrust bearing or the balancing.
The aim is d'adjust the compression capacity and flow rate' d'air'. However, a hybrid turbo is not defined solely by the appearance of its impeller: the harmony between the impeller, the housings, the rotor and the engine settings remains crucial.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process does not, on its own, guarantee an increase in throughput d'air'. A standard MFS wheel can maintain a geometry equivalent to that d'origin'.
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 wheel Performance may use a blade profile, dimensions or configuration suited to the preparation objective. A higher flow rate can help to generate more power only if the engine has been properly prepared.
The compressor wheel draws in and then compresses the air fed to the engine. Its diameter, profile, height, width and the arrangement of the blades all influence its aerodynamic behaviour. The right geometry can move more d'air under certain conditions, but the result also depends on the casings, the turbine section, the boost pressure and the engine management system'. A larger wheel therefore does not automatically guarantee better performance and may affect response time.
The documented 360° bearing stop helps to distribute the axial forces acting on the rotating assembly. The rotor is balanced at high speed – up to 150,000 rpm – on a Cimat VSR test bench, in order to minimise vibrations and mechanical stresses. However, this balancing does not compensate for either incorrect installation or inadequate lubrication.
Appropriate engine management is required for make the most of the hybrid turbo’s features. Depending on the level of preparation, the mapping, the boost pressure, the fuel injection and the air cooling d'The intake, exhaust and transmission must be checked or adjusted'. The wastegate must be adjusted during the fitting and remapping of the ECU.
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Before installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the supply and the return d'oil, the cleanliness of the pipes, the intake and the absence of foreign objects'. Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions. You should also check the wastegate setting whilst fitting and reprogramming the unit. If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
Check the turbo part number d'Origin, OEM and manufacturer part numbers, as well as the make, model, generation, body style, engine type, power output, years of manufacture and engine code'. Having the same engine is not always enough to confirm compatibility.
⚠️ 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 are in any doubt, please contact us, quoting the reference number clearly visible on your turbo d'the vehicle's origin and specific details'.

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.
