This hybrid turbo is designed for use with the following engines Kia Sorento 2.5 CRDi 170 hp. Depending on the upgrade package chosen, the modification comprises a high-flow MFS compressor wheel, a 360° bearing stop and appropriate internal modifications.
The three documented levels allow you to choose a configuration comprising modifications to the compressor side and, for the Stage 3, to the turbine side. Each tuning package includes d high-speed balancing at 150,000 rpm on a Cimat VSR test bench.
Available configurations — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor impeller: MFS high-flow
Bearing stop: 360°
Balancing: 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor wheel’s ability to move air. Its final performance depends on the engine’s configuration and its management system.
Stage 2
Compressor wheel: MFS high-flow oversized
d intake housing: Reprofiled for to accommodate the new impeller oversized
Bearing thrust: 360°
Balancing: 150,000 rpm on a Cimat VSR test bench
Stage 2 combines a oversized compressor wheel with a reprofiled d intake housing. This modification is designed to alter the compression capacity and air flow rate d, without making any assumptions about the final result on the engine.
Stage 3
Compressor impeller: MFS high-flow oversized
d intake housing: Reprofiled for to accommodate the new impeller oversized
Bearing thrust ring: 360°
Turbine impeller: High-flow oversized
Turbine housing: Reprofiled for ly to accommodate the new impeller oversized
Balancing: 150,000 rpm on a Cimat VSR test bench
This configuration includes modifications to both the compressor and turbine sides. Oversizing may affect flow rate and response time; the result depends on the overall engine preparation.
What is a hybrid turbo?
A hybrid turbo utilises a turbocharger architecture adapted for to accommodate modified internal components. Depending on the stage, the modification 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 air flow rate d. A hybrid turbo is not defined solely by the appearance of its impeller: the geometry of the components and how they are combined are 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 can 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. Depending on its design, an impeller Performance may have a profile or dimensions suited to the set-up. A higher flow rate can help generate more power with appropriate engine management, though this does not guarantee a specific gain.
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 blade arrangement influence its aerodynamic behaviour. A suitable geometry can move more d air under certain conditions, but the result also depends on the housings, the turbine, the boost pressure and the engine tuning. A larger impeller therefore does not automatically guarantee better performance and may alter the response time.
Reliability and balancing of the hybrid turbocharger
The documented 360° bearing stop helps to distribute axial forces. Rotor balancing limits vibrations and mechanical stresses: all three stages are balanced at 150,000 rpm on a Cimat VSR test bench. However, this balancing does not compensate for incorrect installation or inadequate lubrication.
Engine remapping and preparation
To make the most of the characteristics d of a hybrid turbo, it may be necessary to adjust the mapping, boost pressure and fuel supply. The intercooler, the exhaust, the clutch or the transmission may also need to be checked, depending on the vehicle and the level of tuning. Fitting d a hybrid turbo does not automatically 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, the inlet and that there are no 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 turbo’s part number d, the original OEM and manufacturer part numbers, as well as the make, model, engine type, power output,Year and engine code.. An identical engine type does not always guarantee 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 product sheet. An identical engine specification does not always guarantee compatibility.
If you are unsure about the identification, please contact us before placing your order.
