Hybrid Turbo Fiat Ducato 2 3 120 – 504340182, 49135-05132. MJTD hp
Description
This hybrid turbo is designed for the Fiat, Ducato 2., 3 MJTD 120 from 2006 onwards. Depending on the upgrade package chosen, the modification is based on a high-flow MFS compressor wheel, a 360° bearing stop and appropriate internal modifications.
The configurations on offer allow you to select a level of tuning consistent with your engine project, without claiming any undocumented final power figures.
Available tuning packages — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: high-flow MFS
Bearing: 360° thrust
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor section in order d to adjust the compression capacity and the d air flow rate of the turbo.
Stage 2
Compressor wheel: high-flow MFS oversized
Intake casing d: re-profiled for accommodate the new impeller oversized
Bearing: 360° thrust
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
Reprofiling of the casing allows d to accommodate the compressor impeller oversized. This configuration may alter the air flow rate d and the compressor’s behaviour depending on the engine settings.
Stage 3
Compressor impeller: high-flow MFS oversized
d'intake housing: re-profiled for to accommodate the new impeller oversized
Bearing: 360° thrust bearing
Turbine impeller: high-flow oversized
Turbine casing: re-profiled for ly to accommodate the new impeller oversized
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR test bench
This modification applies to both the compressor and turbine sides. The oversized impellers and re-profiled housings must be combined with engine tuning appropriate to the intended use.
What is a hybrid turbo?
A hybrid turbo retains a turbocharger architecture suitable for accommodate modified internal components. Depending on the stage, the modification may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system and balancing.
The aim is d to adapt the compression capacity and air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the wheels and the overall coherence of the unit 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 impeller may retain a geometry equivalent to the original. An MFS impeller Performance may be given a geometry adapted to the modification, particularly in terms of profile or dimensions, provided these modifications are documented.
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. A higher airflow can contribute to an increase in power only with appropriate engine tuning.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and compresses the air sent to the engine. Its diameter, profile, height, width and blade arrangement all influence its aerodynamic behaviour. The result also depends on the housings, the turbine, the boost pressure and the engine management system. 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° thrust bearing, documented across the three stages, distributes axial forces over a wide surface area. It helps the bearing adapt to the stresses of the modification, without making the turbo immune to faults in assembly or lubrication.
The rotor is balanced at high speed, up to 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses on the rotating assembly.
Engine remapping and tuning
The engine mapping and wastegate settings must be adjusted for to make the most of the turbo’s characteristics. Depending on the level of tuning, the fuel injection, exhaust system, cooling, boost pressure management and the transmission may also require checking or adjustment. The hybrid turbo alone does not guarantee a power gain.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d installing the turbo. Check the lubrication system, the oil supply and return d, as well as the cleanliness of the pipes.
Check the intake 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 of the original turbo d and compare it with the OEM and manufacturer part numbers in this datasheet. Also check the make, model, engine type, power output (120 hp), installation period and, if available, the 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 part number from your original turbo d.
