Hybrid Turbo 1.4 D-4D 90 hp – 17201-0N051, 780709
Description
This hybrid turbo, designed for a 1.4 D-4D engine producing 90 hp, is available in several tuning levels. It is designed to be fitted without any modifications to the original d mounting, whilst its internal components are adapted according to the selected tuning stage.
The documented tuning packages combine a high-flow MFS compressor wheel, a 360° thrust bearing and high-speed balancing. The higher-spec packages add oversized wheels and re-profiling of the relevant housings.
Available set-ups — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrustbearing: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor wheel in order d to adjust the compression capacity and d air flow, whilst retaining the original turbo d mounting configuration for.
Stage 2
Compressor wheel: MFS high-flow oversized
Intake housing d: re-profiled for to accommodate the new impeller
Thrustbearing: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
The oversized impeller requires the intake housing to be re-profiled d. This combination may promote a higher air flow d, but its performance also depends on the engine management system and the overall configuration.
Stage 3
Compressor wheel: MFS high-flow oversized
Intake housing d: re-profiled for to accommodate the new impeller
Thrustbearing: 360°
Turbine impeller: high-flow oversized
Turbine casing: reprofiled for ly to accommodate the new impeller
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This level combines modifications to the compressor side with a turbine impeller oversized and a reprofiled turbine housing. These changes may affect flow rate and response time; they must be integrated into a coherent engine tuning programme.
Understanding hybrid tuning
What is a hybrid turbo?
A hybrid turbo features an architecture designed for accommodate internal modifications. Depending on the tuning package, these may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system or balancing. The aim is d to adapt the compression capacity and air flow rate d without reducing the tuning to merely the visual appearance of the components.
MFS compressor impeller: standard or ‘ Performance ’?
MFS stands for ‘Milled From Solid’, i.e. a wheel machined from a solid block. This manufacturing process does not, on its own, guarantee an increase in air flow rate. A standard MFS wheel may retain a geometry equivalent to the original, whilst a Performance wheel may adopt a geometry tailored to the tuning objective.
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 only with appropriate engine tuning.
Why does the blade geometry influence the air flow rate d?
The impeller diameter, the profile, height, width and arrangement of the blades all influence air intake and compression. The result also depends on the housings, the turbine wheel, the boost pressure and the mapping. A larger wheel therefore does not automatically guarantee a better result 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. Balancing the rotor at 150,000 rpm on a Cimat VSR test bench aims to minimise vibrations and mechanical stresses. However, it does not compensate for incorrect installation or inadequate lubrication.
Engine remapping and preparation
Adjustments to the mapping and boost pressure management are necessary for to make full use of the turbo’s characteristics. The fuel injection, exhaust, cooling, intake and transmission must also be checked depending on the level of tuning. The wastegate must be adjusted when remapping the ECU.

Fitting instructions
⚠️ 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. Ensure the pipes are clean, 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 part number marked on the turbo d the original, OEM and manufacturer part numbers, as well as the model, generation, body style, engine type, power output,Year and engine code. An identical engine type is not always sufficient to confirm 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 details you have noted from your turbo.
