This hybrid turbo for engine options Opel 2.0 i is available in three different preparation levels. Depending on the course chosen, he receives an MFS compressor wheel Performance high flow rate, a 360° bearing stop and high-speed balancing on a Cimat VSR test bench.
The applications documented include, in particular, the Opel Astra, Speedster, Vectra, VX 220 and Zafira, with power outputs ranging from 170 to 220 hp. Compatibility must be confirmed using the turbo’s part number d’origin’.
Available products — Stage 1, Stage 2 and Stage 2+
Stage 1
Compressor wheel: MFS Performance high-speed
Dimensions: 38.10 / 50.96 mm
Blade configuration: 4+4
Bearing stop: 360°
Balancing: high speed at 150,000 revolutions per minute on a Cimat VSR test bench
This setup uses an MFS wheel Performance whose geometry is designed for adjust the travel capacity dcompressor air. Its ultimate performance depends on the engine configuration and the management of the boost.
Stage 2
Compressor wheel: MFS Performance high-speed oversized
Dimensions: 42.00 / 56.08 mm
Blade configuration: 11+0
Carter d’Admission:’ reprofiled for to accommodate the wheel oversized
Bearing stop: 360°
Balancing: high speed at 150,000 revolutions per minute on a Cimat VSR test bench
The larger diameter of the wheel requires the casing to be re-profiled d’admission’. This combination aims to adapt the airflow to the new geometry, although it cannot, on its own, guarantee a specific engine power output.
Stage 2+
Compressor wheel: MFS Performance high-speed oversized
Dimensions: 50.00 / 62.50 mm
Blade configuration: 10+0
Carter d’Admission:’ reprofiled for to accommodate the wheel oversized
Bearing stop: 360°
Balancing: high speed at 150,000 revolutions per minute on a Cimat VSR test bench
This design uses a larger-diameter impeller and a specific blade configuration. Such a change may affect the flow rate dair flow, response time and the turbocharger’s optimum operating range.
What is a hybrid turbo ?
A hybrid turbo is based on a specially adapted turbocharger design for to receive internal components that differ from the configuration d’origin’. Modifications may relate to the compressor impeller, its dimensions and geometry, the casings, the turbine impeller, the thrust bearing system or the balancing process.
The aim is d’adjust the compression capacity and flow rate’ d’air in a given preparation’. A hybrid turbo is therefore not defined solely by the appearance of its impeller, and a larger impeller is not automatically preferable in all conditions.
MFS compressor wheel: standard or Performance ? ?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This designation 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 Depending on the design, it may use a blade diameter, profile or 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 higher flow rate can help to increase power output when the engine has been properly tuned.
Why does the geometry of the blades affect the flow rate? d’air ?
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 its aerodynamic behaviour and its ability to move air under different operating conditions.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine tuning. An increase in size may affect the response time and range doptimal use.
Reliability and balancing of the hybrid turbocharger
The 360° stop, as documented in the three training courses, distributes the axial forces across the entire circular surface. It helps to adapt the bearing to operational stresses, without making the turbocharger insensitive to faults in assembly or lubrication.
Every preparation benefits from d’high-speed balancing at 150,000 revolutions per minute on a Cimat VSR test bench’. The aim of this operation is to minimise vibrations and mechanical stresses on the rotor.
Engine remapping and tuning
Appropriate engine management may be required for make the most of the hybrid turbo’s features. Mapping, boost pressure and wastegate adjustment must be checked during installation and remapping.
Depending on the level of preparation, the fuel system, exhaust, cooling system, intake, clutch or transmission may also need to be checked or adjusted. The hybrid turbo alone does not guarantee a power boost.

Assembly instructions
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Before installation, it is essential to investigate and rectify the cause of the previous fault. 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 turbocharger spool-up in accordance with the relevant guidelines and follow the manufacturer’s instructions.
The wastegate and engine management system must be adjusted in line with the chosen set-up. Systems d’injection, dThe exhaust and cooling systems must also be checked and adjusted if necessary.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
How do you choose the right turbo ?
Make a note of the reference number engraved or printed on the plate dTurbo identification dthe original, then compare it with the OEM and manufacturer’s part numbers listed on this sheet. Also check the make, model, generation, engine type and power output in hp, theYear installation details and, where available, the engine code.
The same engine can be fitted with several different turbocharger set-ups. Simply matching the model or engine capacity is therefore not always sufficient 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 with the full part number of your turbocharger d’origin’.
