This hybrid turbocharger is designed for petrol engines Smart 0.6i and 0.7i combines a GT1238S architecture with an MFS compressor wheel Performance. The documented procedures are designed to adjust the flow rate d’air whilst retaining a configuration d’installation’ plug & play.
It covers several versions of the Smart Cabrio and City-Coupé 450, as well as the Crossblade 450 and Roadster 452, depending on the turbocharger model, engine and power output.
This system is based on an MFS compressor wheel Performance suitable for the flow rate d’a sophisticated look’. The 360° stop helps to distribute axial forces, whilst high-speed balancing is designed to minimise rotor vibrations.
The Stage 2 is fitted with a larger compressor wheel and a casing d’re-profiled intake’. This change may affect the compressor’s flow capacity and behaviour; its operation depends on the engine’s overall configuration and the mapping.
A hybrid turbo uses a specially adapted turbocharger design for to receive internal components or machined parts that differ from the specification d’origin’. Depending on the modification, changes may relate to the compressor impeller, its dimensions, the geometry of the blades, 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 needs dengine tuning. However, a hybrid turbo is not defined solely by the appearance of its impeller: consistency between the components and settings remains essential.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This term 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, depending on its design, use a blade diameter, profile or arrangement 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 higher flow rate can help to increase power output when the engine has been properly tuned.
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 and the quantity d’air displaced within certain operating ranges’.
The result also depends on the compressor housing, the turbine section, the boost pressure and the engine tuning. A larger wheel therefore does not automatically guarantee better performance and may affect response time as well as the range doptimal use.
The two documented work placements involve da 360° stop, designed for to distribute the axial forces acting on the rotating assembly more evenly. It does not exempt d’proper lubrication nor d’a compliant installation’.
The rotor is balanced at high speed, up to 150,000 revolutions per minute, on a Cimat VSR test bench. The aim of this operation is to minimise vibrations and mechanical stresses, without compensating for a fault d’installation, contamination or an inadequate oil supply.
The engine management system needs to be adjusted for make the most of the hybrid turbo’s features. The wastegate must be adjusted during the installation and remapping of the ECU.
Depending on the level of preparation, it is also advisable to check the mapping, boost pressure, fuel injection, exhaust system and air cooling d’intake and transmission’. The editing dA hybrid turbo alone does not guarantee a power boost.
⚠️ 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’the oil and the cleanliness of all the pipes’.
Check the intake and ensure there are no foreign objects. Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions. The wastegate must be adjusted during installation and when fine-tuning the map.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
Check the part number engraved or marked on the turbocharger dthe original, then compare the OEM and manufacturer part numbers. Also check the make, model, generation, body style, engine type and power output in hp, the assembly period and the engine code.
The same engine can be fitted with several different turbocharger set-ups. Checking the reference therefore remains the most reliable way of confirming the assignment.
⚠️ 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 full part number of your turbocharger and your vehicle details.

View standard exchange turbochargers →Hybrid turbos are designed for set-ups requiring greater air flow d and higher performance potential than a standard set-up. Specifications depend on the turbo, its tuning and the engine configuration.
View hybrid turbos →The turbo Cartridge, also known as the central turbo cartridge, comprises the main rotating components of the turbocharger. ALFI TURBO has over 6,000 Cartridge for turbo part numbers.
View turbo Cartridge →Our catalogue covers a wide range of d applications fitted with d a turbocharged engine.
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.
