This hybrid turbo for, with an engine code of Volkswagen, 2., 5 TDI and a power output of 130 hp, is available in three distinct tuning levels.. Each version is fitted with an MFS compressor wheel Performance suited to its tuning stage, a 360° bearing stop and high-speed balancing.
Documented applications include, in particular, the Volkswagen, California T5, Multivan V and Transporter V models fitted with the engine codes listed in this data sheet.
Available upgrades — Stage 1, Stage 2 and Stage 2+
Stage 1
Compressor wheel: MFS high-flow
Dimensions: 36.39 / 49.00 mm
Blade configuration: 11+0, profile Performance
Bearing: 360° thrust
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This set-up is based on an MFS Performance wheel designed to adapt the air flow rate d whilst retaining a configuration intended for for a Installation without modification vehicle. The final performance depends on the engine management system and all associated components.
Stage 2
Compressor wheel: MFS high-flow oversized
Dimensions: 40.10 / 52.19 mm
Blade configuration: 7+7, profile Performance
Casing d Inlet: reprofiled for to the impeller oversized
Bearing: 360° thrust
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
The oversized impeller and the reprofiling of the intake housing d allow d the compression capacity and air flow rate d to be adjusted. This modification may also alter the response time and must be combined with appropriate engine tuning.
Stage 2+
Compressor impeller: MFS high-flow oversized
Dimensions: 41.52 / 56.02 mm
Blade configuration: 11+0, profile Performance
d intake housing: re-profiled for the impeller oversized
Bearing: 360° thrust
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This upgrade uses a larger-diameter impeller and a reprofiled intake housing d. Its effectiveness depends on the engine’s overall configuration and does not, on its own, guarantee superior power or response under all conditions.
What is a hybrid turbo?
A hybrid turbo utilises a turbocharger architecture adapted for to accommodate modified internal components. Depending on the upgrade package, the modifications may involve the compressor wheel, its diameter, the blade geometry, the intake housing d, the thrust bearing system and 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 consistency of its mechanical characteristics.
MFS compressor wheel: standard or Performance?
MFS stands for ‘Milled From Solid’: the impeller is machined from a solid block. This manufacturing process alone does not guarantee an increase in air flow rate d. A standard MFS impeller may retain a geometry equivalent to that d of the original.
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. On the set-ups presented here, the dimensions and blade configurations vary depending on the stage.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air. Its diameter, profile, height, width and blade arrangement all influence its aerodynamic behaviour. A suitably designed geometry can move more d air under certain conditions, but the result also depends on the casings, the turbine, the boost pressure and the engine tuning. A larger impeller does not automatically guarantee better performance 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. The rotor is balanced at 150,000 rpm on a Cimat VSR test bench to minimise vibrations and mechanical stresses. However, this balancing does not compensate for inadequate lubrication or incorrect installation.
Engine remapping and preparation
Adjustments to the engine management system may be necessary for to make the most of the hybrid turbo’s characteristics. The mapping, boost pressure, fuel injection, air cooling d, the intake, exhaust and transmission must be checked according to the level of tuning.. The wastegate must be adjusted during fitting and remapping.. No power gain is automatic without the correct configuration.

Fitting instructions
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return d as well as the cleanliness of the oil lines. Check the intake for any foreign objects, then prime the system in accordance with the applicable recommendations. Follow the manufacturer’s instructions and have the wastegate adjusted during fitting and remapping. A lubrication fault that is not rectified may lead to the turbocharger failing again.
How do you identify the correct turbo?
Check the turbo part number d, the original, OEM and manufacturer part numbers, as well as the model, generation, body style, engine type, power output, production period 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 part number from your turbocharger.
