This hybrid turbocharger for, designed for the 1.3 CDTI 90 hp engine, is available in three performance levels.. Its design allows for Installation without modification, whilst its internal components are adapted to the chosen performance level in order to adjust the compression ratio and dair flow rate.
It is designed for the applications Opel Astra H, Astra MKV and Corsa D documented below. Consistent tuning of the engine management system and peripherals is required for to make the most of the turbo’s characteristics.
This modification primarily affects the compressor impeller. The documented MFS impeller is lighter, larger and taller than the original one d, with a claimed 15 per cent increase in compression capacity.
The Stage 2 combines a oversized compressor impeller with a reprofiled dintake housing. This modification is designed to correctly accommodate the new impeller and increase the compressor’s air flow d.
Stage 3 modifies the compressor and turbine sides. The resulting performance depends on the overall engine configuration, and increasing the size of the impellers may also alter the response time and the range d’optimal operation.
A hybrid turbo utilises a turbocharger architecture adapted for to accommodate modified internal components. Depending on the upgrade stage, modifications may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing system or balancing.
The aim is dto adapt the compression capacity and air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the parts and how they are combined determine its performance.
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 d. A standard MFS wheel may retain a geometry equivalent to that dof the original.
A standard MFS impeller can be just as shiny as an MFS impeller Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d’air. An Performance impeller may have a profile or dimensions adapted to the tuning objective when such modifications are planned.
The compressor impeller draws in and then compresses the air. Its diameter, profile, height, width and arrangement of its blades all influence its aerodynamic behaviour. The result also depends on the casings, the turbine, the boost pressure and the engine tuning. A larger impeller therefore does not automatically guarantee a better result in all conditions.
The 360° thrust bearing distributes axial forces over a wide surface area. Each stage presented is fitted with one. The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench to minimise vibrations and mechanical stresses. This balancing does not compensate for incorrect fitting or inadequate lubrication.
Operating da hybrid turbo requires appropriate engine management. The mapping, boost pressure, fuel injection, cooling, exhaust and, depending on the configuration, the transmission must be checked or adjusted. The wastegate must be adjusted when remapping the ECU. Fitting the turbo alone does not guarantee a 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 lines d, the cleanliness of the pipes, the inlet and the absence of foreign objects.. Prime the system in accordance with the applicable recommendations and follow the manufacturer’s instructions.. An uncorrected lubrication fault may result in further turbocharger failure.
Check the turbo’s part number d, the original OEM and manufacturer part numbers, as well as the make, model, generation, engine type, power output,Year and engine code.. An identical engine type is not always sufficient to confirm compatibility.
⚠️ 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 specification does not always guarantee compatibility.
If in doubt, please contact us with the part number from 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.
