This hybrid turbo for engine 1.9 TDI 150 hp is available in three levels of preparation. Depending on the course chosen, he receives an MFS compressor wheel Performance high flow rate, a 360° bearing stop and high-speed balancing carried out on a Cimat VSR test bench.
The documented assignments relate in particular to Audi A3, Seat Ibiza, León and Toledo, as well as the Volkswagen Bora, Golf IV and Jetta 4. The benchmark for turbochargers dThe origin must be verified before any order is placed.
Available products — Stage 1, Stage 2 and Stage 2+
Stage 1
Compressor wheel: MFS Performance high-speed
Dimensions: 36.39 / 49.00 mm
Blade configuration: 11+0
Bearing stop: 360°
Balancing: high speed at 150,000 rpm on a Cimat VSR test bench
This kit includes an MFS wheel Performance high flow rate with a 360° stop. Its geometry is designed to adapt the range of movement d’compressor air, although no precise increase in power can be deduced from these characteristics alone’.
Stage 2
Compressor wheel: MFS Performance high-speed oversized
Dimensions: 40.10 / 52.19 mm
Blade configuration: 7+7
Carter d’Admission:’ reprofiled for to receive the wheel oversized
Bearing stop: 360°
Balancing: high speed at 150,000 rpm on a Cimat VSR test bench
The Stage 2 is based on a larger wheel and a redesign of the casing d’admission’. This modification is designed to accommodate the new geometry correctly and may affect the flow rate d’air and the turbocharger’s response.
Stage 2+
Compressor wheel: MFS Performance high-speed oversized
Dimensions: 41.52 / 56.02 mm
Blade configuration: 11+0
Carter d’Admission:’ reprofiled for to receive the wheel oversized
Bearing stop: 360°
Balancing: high speed at 150,000 rpm on a Cimat VSR test bench
The Stage 2+ uses an MFS wheel Performance oversized and a casing d’re-profiled intake’. Increasing the dimensions may improve flow capacity under certain conditions, but it may also affect response time and requires a consistent motor configuration.
What is a hybrid turbo ?
A hybrid turbo retains a suitable turbocharger design for to receive internal components or machined parts that differ from the specification d’origin’. Depending on the modification, changes may relate to the compressor impeller, its geometry, its dimensions, the casings, the turbine impeller, the thrust bearing system or the balancing.
The aim is d’adjust the compression capacity and flow rate’ d’air for a specific engine setting’. A hybrid turbocharger is therefore not defined solely by the appearance of its impeller: the overall mechanical integrity remains essential.
MFS compressor wheel: standard or Performance ? ?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This term describes the manufacturing process, but does not in itself guarantee an increase in throughput dair. A standard MFS wheel can retain a geometry equivalent to that d’origin’.
An MFS wheel Performance may adopt a geometry specific to the intended purpose, in particular a different profile, diameter or blade configuration, where these elements are documented.
A standard MFS wheel can be just as shiny as an MFS wheel Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more dair. A higher flow rate can help to generate more power with the right engine tuning, although this does not in itself guarantee a performance gain.
Why does the geometry of the blades affect the flow rate? d’air ?
The compressor wheel draws in and then compresses the air fed to the engine. Its diameter, profile, height, width and the arrangement of its blades influence the aerodynamic behaviour of the compressor. The right geometry can move more dair within certain operating ranges.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine tuning. A larger wheel does not automatically guarantee better performance and may affect response time.
Reliability and balancing of the hybrid turbocharger
The 360° stop fitted to all three stages helps to distribute the axial forces acting on the rotating assembly. However, it does not exempt one from d’proper lubrication nor d’a compliant installation’.
Every preparation benefits from d’high-speed balancing at 150,000 rpm on a Cimat VSR test bench’. This procedure is designed to minimise vibrations and mechanical stresses on the rotor, but does not protect against contamination or faults d’oil or incorrect installation.
Engine remapping and tuning
The engine management system needs to be adjusted for make the most of the hybrid turbo’s features. Mapping, boost pressure, fuel injection, air cooling dThe intake, exhaust and, depending on the vehicle, the clutch or gearbox must be checked. The wastegate must be adjusted during the installation and remapping of the ECU. No increase in power happens automatically without proper preparation.

Assembly instructions
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Before installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the supply and the return doil, the cleanliness of the pipes, and the intake, as well as the absence of foreign objects.
Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions. The engine management system and the wastegate must be set in accordance with the selected stage.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
How do you choose the right turbo ?
Check the part number on the turbocharger d’origin, OEM and manufacturer part numbers, as well as the make, model, generation, engine type, power output, theYear installation and engine code. An identical motor does not always guarantee full compatibility.
⚠️ Check your turbo’s part numbers
Before placing your order, Compare the part number on your turbocharger d'origin' using the references given in this fact sheet. Having the same motor does not always guarantee compatibility.
If you are in any doubt, please contact us with the full part number from your turbocharger.
