This hybrid turbocharger, designed for the Suzuki Grand Vitara I 2.0D with a 109 hp engine, features dan internal modification aimed at optimising the dair flow and the behaviour of the turbocharger. It is designed plug & play to be fitted without any modifications to the doriginal system.
The tuning packages on offer include a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing, with additional modifications depending on the package chosen.
Available upgrades — 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 bench
This modification primarily affects the compressor impeller in order dto adapt the air displacement capacity dwhilst retaining a configuration designed for for direct integration.
Stage 2
Compressor wheel: MFS high-flow oversized
dIntake casing: reprofiled for accommodate the new impeller
Thrust bearing: 360° thrust bearing
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR test bench
Stage 2 combines a oversized compressor impeller with a reprofiled housing d’admission. This modification is designed to enable the new impeller to operate and to alter the compressor’s flow capacity.
Stage 3
Compressor impeller: MFS high-flow oversized
dintake casing: re-profiled for accommodate the new impeller
Turbine impeller: high flow oversized
Turbine housing: re-profiled for ly to accommodate the new impeller
Thrust bearing: 360° thrust bearing
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR test bench
Stage 3 is fitted on both the compressor and turbine sides of the. The sizing of the impellers and the re-profiling of the housings alter the flow conditions and may also influence the turbo’s response time.
What is a hybrid turbocharger?
A hybrid turbo is based on an existing design that has been adapted for accommodate modified internal components. Depending on the stage, the modifications may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system or the rotor balancing.
The aim is dadapt the compression capacity and air flow dto the requirements of the engine tuning. A hybrid turbo is not defined solely by the appearance of its compressor wheel: its geometry, the machining carried out and the overall coherence of the unit are decisive.
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 air flow d. A standard MFS wheel may retain a geometry close to the original.
An MFS impeller Performance can be given a geometry tailored to the tuning objective. A standard MFS impeller can be just as polished 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.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air admitted by 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 engine calibration. A larger impeller therefore does not automatically guarantee better performance and may alter the response time.
Reliability and balancing of the hybrid turbocharger
The 360° stop helps to distribute the axial forces exerted on the rotating assembly. The rotor is balanced at high speed, up to 150,000 rpm on a Cimat VSR test bench, in order to limit vibrations and mechanical stresses. However, this balancing does not compensate for incorrect installation or inadequate lubrication.
Engine remapping and preparation
Adjustments to the engine mapping and boost pressure management may be necessary for to make the most of the hybrid turbo’s characteristics. Depending on the level of tuning, the fuel injection, exhaust system, cooling system, the clutch or the transmission may also need to be checked. The wastegate must be adjusted when the ECU is remapped. No power gain is automatic without a coherent configuration.

Installation advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
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 the pipes. Check the inlet for foreign objects, then prime the system in accordance with the applicable recommendations. 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 part number dof the original unit, the OEM and manufacturer part numbers, as well as the model, generation, body style, engine type, power output, years of manufacture 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 specification sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, please contact us with the full part number taken from your turbocharger.
