This hybrid turbo for is available for the 2., 2 DTI and 2., 2 TiD engines and is offered in several tuning levels.. Its design plug & play allows for external Installation without modification, whilst the internal modifications vary depending on the tuning stage selected.
It is suitable for the applications Opel and Saab documented below. The MFS compressor wheel Performance, the 360° thrust bearing and high-speed balancing are among the features specified depending on the configuration.
Available configurations — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing: 360° bearing
Balancing: High-speed at 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor impeller in order dto adapt the compression capacity and the air flow rate d. Its operation must remain consistent with engine management and peripheral equipment.
Stage 2
Compressor wheel: MFS high-flow oversized
d’ intake housing: Reprofiled for accommodate the new impeller oversized
Thrust bearing: 360° bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
The Stage 2 combines a oversized compressor impeller with a reprofiled dintake housing. This modification is designed to alter the air displacement capacity dwithout prejudging the final gain, which depends on the engine configuration.
Stage 3
Compressor impeller: MFS high-flow oversized
Intake housing d: Reprofiled for to accommodate the new impeller oversized
Thrust bearing: 360° bearing
Turbine impeller: High-flow oversized
Turbine casing: Reprofiled for ly to accommodate the new impeller oversized
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
This modification is carried out on both the compressor and turbine sides. The oversized impellers and re-profiled housings alter the turbocharger’s behaviour; the result depends in particular on the pressure, the mapping and the engine’s peripheral components.
What is a hybrid turbo?
A hybrid turbo is based on a turbocharger architecture adapted for accommodate internal components that differ from the original dconfiguration. Depending on the upgrade stage, modifications may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing or the balancing.
The aim is d’to adjust the compression capacity and the air flow rate d’. However, a hybrid turbo is not defined solely by the appearance of its impeller: the geometry, the machining of the housings and the balance between the compressor and the turbine are also crucial.
MFS compressor wheel: standard or ‘ 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 flow rate. A standard MFS wheel can retain a geometry equivalent to that of the d’original.
An MFS wheel Performance can feature a geometry tailored to the modification. In this product, the wheel shown is made from forged aluminium; it is lighter, larger and taller than the original d, with a claimed 15 per cent higher compression capacity.
A standard MFS impeller can perform just as well as an MFS Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d’air. A higher airflow can only be fully utilised with appropriate engine tuning.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and blade arrangement all influence its aerodynamic behaviour. The result also depends on the casings, the turbine, the boost pressure and the mapping. A larger impeller therefore does not automatically guarantee better performance and may alter the turbo’s response time.
Reliability and balancing of the hybrid turbocharger
The 360° thrust bearing distributes axial forces around the bearing system. The rotor is balanced at high speeds, up to 150,000 rpm, on a Cimat VSR test bench to minimise vibrations and mechanical stresses. However, this balancing does not compensate for incorrect installation or inadequate lubrication.
Engine remapping and preparation
Adjustments to the mapping and pressure control may be necessary for to make the most of the hybrid turbo’s characteristics. The fuel injection, exhaust, intercooler dintake, clutch or gearbox must also be checked depending on the level of tuning. The wastegate must be adjusted when remapping the ECU. The turbo alone does not guarantee a power gain.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication circuit, as well as the oil supply and return d. Check that the pipes and inlet are clean and free from foreign objects.
Prime the system in accordance with the applicable recommendations and follow the manufacturer’s instructions. A lubrication fault that is not rectified may lead to further turbocharger failure.
How do you identify the correct turbo?
Check the part number marked on the original turbo d, the OEM and manufacturer part numbers, as well as the make, model, generation, engine type, power output, mountingYear and engine code.. An identical engine 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 full part number taken from your turbocharger.
