This hybrid turbo plug & play is designed for VAG 1.8 T engines ranging from 150 to 210 hp. Depending on the selected upgrade package, it features a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing.
The documented applications relate to the Audi A4, Audi A6 and Volkswagen Passat models fitted with the 1.8 T engine. The original turbo part number dmust be checked before placing any order.
Available tuning options — Stage 1, Stage 2 and Stage 2+
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This modification acts on the compressor impeller to d’adapt the flow rate d’air, whilst maintaining the specified Installation without modification.
Stage 2
Compressor impeller: MFS high-flow oversized
Intake casing d: re-profiled for accommodate the new impeller
Thrust bearing: 360° bearing
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 configuration may alter the compressor’s flow rate and response depending on the associated engine tuning.
Stage 2+
Compressor impeller: MFS high-flow oversized
d’ intake housing: re-profiled for accommodate the new impeller
Thrust bearing: 360° bearing
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
The documented specifications for for this variant include the MFS impeller oversized, the re-profiled housing, the 360° thrust bearing and VSR balancing.
What is a hybrid turbocharger?
A hybrid turbo retains an architecture suited to the intended installation whilst incorporating internal modifications. Depending on the specification, these may relate to the compressor impeller, its diameter, the d’intake housing, the thrust bearing system or the rotor balancing.
dThe aim is to adapt the compression capacity and air flow d. However, a hybrid turbo is not defined solely by the appearance of its impeller: its overall geometry and suitability for the engine 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 flow rate. A standard MFS wheel may retain a geometry close to the original.
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 d’air. On this product, the impeller is described as lighter, larger and taller than the d’original, with a claimed 15 per cent higher compression capacity. However, its use depends d’on suitable engine tuning.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the intake air. Its diameter, profile, height, width and blade arrangement influence its aerodynamic behaviour. A suitable geometry can move more dair under certain conditions, but the result also depends on the casings, 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 helps to distribute the axial forces exerted on the rotating assembly. The rotor is balanced at 150,000 rpm on a Cimat VSR test bench to minimise vibrations and mechanical stresses. This balancing does not compensate for incorrect assembly, lubrication faults or the presence dof a foreign object.
Engine remapping and preparation
The mapping and boost pressure must be adjusted for to make the most of the turbo’s characteristics. The wastegate must be adjusted during reprogramming. Depending on the level of tuning, the fuel injection, exhaust system, cooling system, intake and transmission may also need to be checked or adjusted. No power gain can be guaranteed without a coherent engine setup.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before installation. Check the lubrication circuit, the oil supply and return das well as the cleanliness of all lines.
Check the inlet for any 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 damage to the turbocharger.
How do you identify the correct turbo?
Check the part number marked on the original turbo dand compare it with the OEM and manufacturer part numbers in this sheet. Also check the make, model, engine type 1.8 T and power output hp. 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 full part number from your turbo.
