This hybrid turbo for petrol engine 1.4 T-JET is based on an RHF3 architecture designed for in-house preparation. Depending on the course chosen, the student receives a high-flow MFS compressor wheel, a 360° bearing stop and high-speed balancing on a Cimat VSR bench..
Designed for an installation plug & play, it covers several Abarth applications, Alfa Romeo, , Fiat and Lancia. The benchmark for turbochargers dHowever, the origin must be verified before any order is placed.
This assembly combines a high-flow MFS impeller with documented dimensions with a 360° stop. It aims to adjust the compression capacity and flow rate d’air whilst retaining a configuration distinct from the upper stages.
The Stage 2 uses a larger wheel and a casing d’the intake, reshaped accordingly’. This combination may affect the flow rate d’air and the compressor’s behaviour; its operation depends on the engine’s overall configuration.
The Stage 2+ is fitted with an MFS wheel oversized in a 6+6 configuration and a casing d’re-profiled intake’. Its dimensions may help to increase the flow rate d…they may seem different, but they can also affect response time and range doptimal use.
A hybrid turbo retains a turbocharger design compatible with the intended application, whilst incorporating internal modifications. Depending on the specific application, these may relate to the compressor wheel, its dimensions, the geometry of the blades, the machining of the housing, the thrust bearing system or the balancing process.
The aim is d’adjust the compression capacity and flow rate’ dair. However, a hybrid turbo is not defined solely by the appearance of its impeller: the compatibility between the components and the engine tuning remains essential.
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 dair. A standard MFS wheel can retain a geometry equivalent to that d’origin’.
An MFS wheel Performance may have a diameter, profile or blade configuration suited to the intended purpose. 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 flow rate d'Higher-quality air can enable the engine to produce more power with the right tuning, although this alone does not guarantee results'.
The compressor wheel draws in and then compresses the air. Its diameter, profile, height, width and the arrangement of its blades all influence its aerodynamic behaviour. The result also depends on the compressor housing, 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° stop distributes axial forces over a wide area. 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. This balancing does not compensate for incorrect installation, inadequate lubrication or the presence of da foreign body.
It may be necessary to adjust the mapping and pressure management for make the most of the turbo’s features. Fuel injection, exhaust, air cooling dThe intake, clutch or gearbox must be checked in accordance with the level of preparation. The wastegate must be adjusted during the fitting and remapping of the ECU.
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Identify and rectify the cause of the previous fault. Carefully check the lubrication circuit, as well as the supply and return lines doil. Check that the ducts and the intake are clean and free from foreign objects. Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions. If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
Check the part number on the turbo dStart by checking the OEM and manufacturer part numbers, then verify the make, model, generation, body style, power output, years of manufacture and 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 are in any doubt, please contact us with the reference number shown on your turbocharger.

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.
