This hybrid turbocharger for for 2.0 CDTI engines is based on an internal modification designed to adapt the compression ratio and the dair flow. Depending on the upgrade package chosen, it is fitted with a high-flow MFS compressor wheel, a 360° thrust bearing and additional modifications to the wheels or housings.
dDocumented applications include the following models: Opel Astra J, Astra J GTC, Insignia and Zafira C Tourer. Installation is designed to require no modification to the original interface, subject to careful verification of the vehicle’s part numbers and configuration.
This modification primarily affects the compressor impeller to dadapt the air flow rate dwhilst maintaining an installation configuration dthat is compatible with the original interface d.
The Stage 2 combines a oversized compressor impeller with a dintake housing, re-profiled. This combination is designed to adapt the air flow and compression to the dimensions of the new impeller.
Stage 3 includes modifications to the compressor and turbine sides. However, the final performance depends on the overall engine configuration, the required pressure and the mapping used.
A hybrid turbo retains an architecture suited to the vehicle whilst incorporating internal modifications. Depending on the modification, these may involve the compressor wheel, the casings, the turbine wheel, the thrust bearing system or the balancing.
The aim is dto adapt the compression capacity and the air flow rate d. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel: the geometry of the components and how they work together determine its behaviour.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone does not guarantee an increase in air flow rate. A standard MFS wheel may retain a geometry equivalent to that of the original d.
For this product, the high-flow MFS wheel is documented as being lighter, larger and taller than the original dwheel, with a claimed 15 per cent higher compression capacity. Depending on the specification, it may also be oversized and fitted with a re-profiled casing.
A standard MFS impeller can be just as effective as an MFS Performance impeller. It is not its appearance that determines its performance, but its geometry and its ability to move more dair. A higher airflow can only be properly utilised with appropriate engine tuning.
The compressor impeller draws in and then compresses the intake air. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour. A suitable geometry can move more dair under certain conditions, but the result also depends on the casings, the turbine, the boost pressure and the engine management system. A larger impeller does not automatically guarantee a better result and may alter the response time.
The 360° thrust bearing, documented across the three stages, helps to distribute the axial forces exerted on the rotating assembly. It does not replace d’proper lubrication or compliance with fitting requirements.
Each specification listed undergo dhigh-speed balancing at 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses on the rotor, without compensating for inadequate lubrication or incorrect installation.
The engine mapping must be adapted for to make the most of the hybrid turbo’s characteristics. Boost pressure management and wastegate adjustment must be carried out during reprogramming. Depending on the modification, the fuel injection, exhaust system, air- d, intake system, clutch or gearbox must also be checked and, if necessary, adjusted.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return d, as well as the cleanliness of all pipes.
Check the inlet for any foreign objects. Carry out priming in accordance with the applicable recommendations and follow the manufacturer’s instructions.
A lubrication fault that is not rectified may result in the turbocharger failing again.
Check the turbo part number d, the original OEM part numbers and the manufacturer’s part number.. Also check the make, model, generation, body style, engine type, power output hp, theYear and the engine code.. A single engine type may be fitted with several different turbo configurations.
⚠️ 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 the part number clearly visible on your original turbo dand your vehicle 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.
