This hybrid turbo for, with a 1.5 dCi 100 hp engine, features d an internal modification designed to adapt its compression capacity and d air flow. Depending on the upgrade package chosen, it is fitted with a high-flow MFS compressor wheel, a 360° thrust bearing and additional modifications to the casings or the turbine section.
It is specifically designed for the Renault Scénic 2 1.5 dCi 100 from 2003 onwards, subject to checking the part number of the original turbocharger d.
Available upgrades — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Bearing system: 360° thrust bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor wheel in order d to adapt the air flow d. The 360° thrust bearing helps to distribute the axial forces more evenly within the turbocharger.
Stage 2
Compressor wheel: MFS high-flow oversized
d' intake housing: Reprofiled for accommodate the new impeller oversized
Thrust bearing system: 360° thrust bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
The Stage 2 combines a oversized compressor wheel with a reprofiled d intake housing. This configuration is designed to optimise airflow and compression, though it does not, on its own, guarantee a specific power output.
Stage 3
Compressor impeller: MFS high-flow oversized
Casing d: Intake: Reprofiled for to accommodate the new impeller oversized
Thrust bearing system: 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 is carried out on both the compressor and turbine sides. However, the final performance depends on the engine as a whole, the turbocharging management system and the peripheral components.
Hybrid turbo technology
What is a hybrid turbo?
A hybrid turbo is based on a turbocharger architecture adapted 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 balancing.
The aim is d to adapt the compression capacity and the air flow rate d. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel, but by the coherence of the entire mechanical assembly.
MFS compressor wheel: standard or Performance?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This technology primarily describes a manufacturing process and does not, on its own, guarantee an increase in air flow rate d.
A standard MFS impeller may retain a geometry close to the original. An ‘ Performance ’ MFS impeller may feature a geometry adapted to the modification, particularly in terms of its profile or dimensions. On this product, the wheel shown is made of forged aluminium, lighter, wider and taller than the d'original. The technical specification indicates an additional compression capacity of 15 per cent for this configuration.
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 contribute to power output when the engine is correctly tuned.
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 the arrangement of its blades influence its aerodynamic behaviour and its ability to move air.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine set-up. A larger impeller does not automatically guarantee better performance and may alter the response time as well as the optimal operating range d.
Reliability and balancing of the hybrid turbo
The 360° thrust bearing, documented at each production stage, distributes axial forces over a suitable surface. It does not eliminate the need d for correct lubrication or d for proper installation.
The rotor is balanced at high speed, up to 150,000 rpm on a Cimat VSR test bench, to minimise vibrations and mechanical stresses. This balancing does not protect the turbocharger against insufficient 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 wastegate must be adjusted during the ECU remapping.
Depending on the level of tuning, it is also advisable to check or d'adjust' the fuel injection, boost pressure, exhaust system, cooling system, intake system and, if necessary, the clutch or gearbox. The hybrid turbo does not automatically guarantee a power gain without appropriate tuning.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous turbocharger’s failure before installation.
Check the lubrication circuit, the oil supply and return d, as well as the cleanliness of the oil lines.. Also check the intake for any foreign objects.
Prime the turbocharger in accordance with the applicable guidelines and follow the vehicle manufacturer’s instructions.
A lubrication fault that is not rectified may result in 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, engine type 1.5 dCi, power output 100 hp and the period of installation.
An identical engine specification does not always guarantee compatibility, as there may be several different set-ups depending on the vehicle.
⚠️ 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 you are unsure about identification or compatibility, please contact us with the part number clearly visible on your original turbo d.
