Hybrid Turbo Volkswagen Crafter 109 and 136 – 03L253014A, 803955 2.0 TDI hp hp
Description
This hybrid turbo is designed for the Volkswagen Crafter 2.0 TDI with 109 hp and 136 hp. . The kit combines a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing, with additional modifications depending on the selected upgrade package.
Designed for to Installation without modification the original dassembly, it must be paired with a compatible engine configuration and suitable electronic control unit.
Available specifications — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Bearing: 360° thrust
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This configuration primarily affects the compressor side in order dto adjust the compression capacity and the air flow rate d.
Stage 2
Compressor impeller: MFS high-flow oversized
dInlet casing: reprofiled for accommodate the new impeller
Bearing: 360° thrust bearing
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
The reprofiling of the casing enables dto accommodate the impeller oversized. This modification may alter the flow rate and behaviour of the compressor depending on the engine configuration.
Stage 3
Compressor impeller: MFS high-flow oversized
d’ intake housing: re-profiled for accommodate the new impeller
Bearing: 360° thrust bearing
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 modification applies to both the compressor and turbine sides. The larger size should be selected based on the intended use, the desired performance and any planned peripheral adaptations.
What is a hybrid turbo?
A hybrid turbo utilises a turbocharger architecture adapted for accommodate modified internal components. Depending on the stage, the modification may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing system and balancing.
The aim is dto adapt the compression capacity and air flow rate d. A hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the components and how they work together 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 air flow rate. An MFS wheel Performance can be given a geometry tailored to the tuning objective, particularly in terms of the profile or dimensions of the blades.
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.
Why does the geometry of the blades influence the airflow d?
The diameter of the impeller, the profile, height, width and arrangement of the blades all influence the intake and compression of air. The result also depends on the casings, the turbine, the boost pressure and the engine tuning. A larger impeller therefore does not automatically guarantee a better result and may alter the response time.
Reliability and balancing of the hybrid turbo
The 360° thrust bearing distributes axial forces over a wide surface area. Balancing the rotor at 150,000 rpm on a Cimat VSR test bench helps to limit vibrations and mechanical stresses, though it does not compensate for poor installation or inadequate lubrication.
Engine remapping and preparation
Adjustments to the mapping and boost management may be necessary. The fuel injection, exhaust, air cooling d’intake, clutch or transmission must also be checked depending on the level of preparation. The wastegate must be adjusted when remapping the ECU.

Installation advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return lines d, then check that the pipes and inlet are clean and free from 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 turbo’s part number d, the original OEM and manufacturer part numbers, as well as the make, model, engine type, power output, production period 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 data sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, please contact us with the part number found on your turbocharger.
