This for hybrid turbocharger, designed for the 2.2 CRDi engine, features d mechanical modifications intended to adapt the compression ratio and d air flow. It is designed for for a plug & play installation, requiring no d modifications to fit the vehicle, and is fitted with an MFS compressor wheel and a 360° bearing retainer.
The documented application covers the Hyundai Santa Fe 2.2 CRDi with 149 hp. Several tuning levels are available to meet different engine performance objectives, with no predefined final power output.
Available tuning options — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Bearing thrust: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor impeller in order d to adapt the flow rate d to the air, whilst maintaining a configuration designed for for direct installation.
Stage 2
Compressor impeller: MFS high-flow oversized
Intake casing d: re-profiled for accommodate the new impeller oversized
Bearing thrust ring: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
dThe oversizing of the compressor impeller is accompanied by a reprofiling of the intake casing d. This combination aims to increase the air displacement capacity d, with performance that depends on the engine’s configuration and settings.
Stage 3
Compressor wheel: MFS high-flow oversized
d'intake' housing: re-profiled for to accommodate the new impeller oversized
Bearing stop: 360°
Turbine impeller: high-flow oversized
Turbine casing: re-profiled for ly to accommodate the new impeller oversized
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This version combines the modifications to the compressor side with a turbine impeller oversized and a re-profiled turbine housing. The assembly adjusts the gas and air flow capacities, but can also alter the response time and the range d for optimum performance.
What is a hybrid turbo?
A hybrid turbo utilises 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 and the balancing.
The aim is d to adapt the compression capacity and d air flow. However, a hybrid turbo is not defined solely by the appearance of its impeller: the geometry, the combination of components and the engine tuning all play a vital role.
MFS compressor wheel: standard or Performance?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This term describes a manufacturing process and does not, in itself, guarantee an increase in airflow d'air. A standard MFS wheel may retain a geometry equivalent to that d'of the original.
An MFS impeller Performance can be tailored to the build: height, width, profile, diameter or blade arrangement. The specifications for this product describe a forged aluminium impeller, which is lighter, larger and taller than the d original, with a claimed 15 per cent increase in compression capacity.
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. A higher airflow can help to generate more power when the engine tuning is correctly adapted.
Why does the geometry of the blades influence the air flow rate d?
The compressor wheel draws in and then compresses the air sent to the engine. Its diameter, the blade profile, their height, width and arrangement directly influence its aerodynamic behaviour.
A suitably designed geometry can move more air d under certain conditions. The result also depends on the casings, the turbine wheel, the boost pressure and the engine mapping. A larger wheel therefore does not automatically guarantee better performance and may alter the response time.
Reliability and balancing of the hybrid turbo
The documented 360° thrust bearing distributes axial forces over a wide surface area. It helps the bearing system adapt to the stresses of the modification, without eliminating the need d for proper lubrication and d correct installation.
The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR balancing machine. This balancing is intended to minimise vibrations and mechanical stresses, but does not protect against inadequate lubrication, contamination or incorrect installation.
Engine remapping and preparation
The engine management system must be adapted for to make the most of the hybrid turbo’s characteristics. The wastegate must be adjusted during the ECU reprogramming.
Depending on the desired outcome, the fuel injection, boost pressure, exhaust system, intake air cooling d as well as the clutch or gearbox must be checked and, if necessary, adjusted. Simply fitting the turbocharger does not guarantee a power increase.

Fitting instructions
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Before installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return d'oil lines, as well as the cleanliness of all pipes. Check the inlet and ensure 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 part number marked on the original turbo d, then compare the OEM and manufacturer part numbers.. Also check the make, model, generation, body style, engine type, power output at hp, theYear and the engine code where available.
The same engine may be fitted with several different turbocharger configurations. Checking the part numbers therefore remains the most reliable way d to identify the correct configuration.
⚠️ 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 part number clearly visible on your original turbocharger d.
