This hybrid turbo for, designed for the 2.0 T engine producing 175, hp, can be fitted plug & play without any modifications to the original assembly d. . The available upgrades combine a high-flow MFS compressor wheel, a 360° bearing stop and high-speed balancing.
Documented applications include the Saab 9.3 and 9.5 from 2002 onwards, as well as the Signum model listed in the original specification d.
Available preparations — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing: 360° thrust bearing
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor impeller in order d to adapt the compression capacity and the air flow rate d. The documented MFS geometry is lighter, larger and taller than the original d, with a claimed 15 per cent increase in compression capacity.
Stage 2
Compressor wheel: MFS high-flow oversized
d' intake housing: re-profiled for accommodate the new impeller oversized
Thrust bearing: 360° thrust 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 d intake casing. This modification is designed to correctly accommodate the new impeller and optimise its aerodynamic performance, without prejudging the engine’s final power output.
Stage 3
Compressor impeller: MFS high-flow oversized
Casing d Inlet: re-profiled for to accommodate the new impeller oversized
Thrust bearing: 360° thrust 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 alters both the compressor and turbine sides. The resulting performance depends on the overall configuration, in particular the engine management system, boost pressure and the intake d and exhaust d circuits.
What is a hybrid turbo?
A hybrid turbo is based on a turbocharger architecture adapted for to accommodate internal components that differ from the original configuration d'. 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 adapt the compression capacity and the air flow d. However, a hybrid turbo is not defined solely by the appearance of its impeller: the compatibility between the impellers, the housings and the engine tuning remains 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 airflow d. A standard MFS wheel may retain a geometry equivalent to that d of 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. With appropriate engine tuning, a higher airflow can help to develop more power, without any automatic gain or guaranteed final power output.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour. A suitable geometry can move more d'air under certain conditions, but the result also depends on the casings, the turbine wheel, the boost pressure and the mapping. A larger wheel can also alter the response time and the range d'of optimal.
Reliability and balancing of the hybrid turbo
The documented 360° thrust bearing helps to distribute axial forces. The rotor undergoes d'high-speed balancing at 150,000 rpm on a Cimat VSR test bench to minimise vibrations and mechanical stresses. This balancing does not compensate for a lack of lubrication, contamination or incorrect installation.
Engine remapping and preparation
The engine management system must be adapted for to make full use of the hybrid turbo’s characteristics. The mapping, boost pressure and wastegate settings must be checked during remapping. Depending on the modification, the fuel injection, exhaust system, air d'intake cooling, clutch or transmission may also require checking or adjustment.

Fitting instructions
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Before fitting, 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 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 the turbocharger failing again.
How do you identify the correct turbo?
Check the part number marked on the original turbo d and compare it with the OEM and manufacturer part numbers in this data sheet. Also check the make, model, generation, body style, engine type 2.0 T, power output of 175 hp, the period of installation and the engine code where available.
An identical engine specification does not always guarantee turbocharger 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 full part number found on your turbocharger.
