Hybrid Turbo 2.2 TDCI 150/155 hp – BK3Q-6K682-PC, 787556
Description
This hybrid turbocharger, designed for a 2.2 TDCI engine producing 150 or 155 hp, features d an internal configuration tailored to the selected performance level. Its configuration is specified as plug & play, whilst the mechanical modifications are carried out inside the turbocharger.
The tuning packages on offer combine a high-flow MFS compressor wheel, a 360° bearing stop and high-speed balancing on a Cimat VSR bench. Higher-level tuning packages include modifications to the wheels and housings.
Available upgrades — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing: 360° thrust bearing
Balancing: 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor section in order d to adapt the compression capacity and the air flow rate d. It retains the specific characteristics of the Stage 1 without applying the machining operations reserved for subsequent stages.
Stage 2
Compressor impeller: MFS high-flow oversized
d' intake housing: re-profiled for to accommodate the new impeller oversized
Thrust bearing: 360° thrust bearing
Balancing: 150,000 rpm on a Cimat VSR test bench
The Stage 2 combines a oversized compressor impeller with a d intake housing, re-profiled. This modification is designed to correctly accommodate the new geometry and utilise its flow potential; however, no final power figure can be deduced from this modification alone.
Stage 3
Compressor impeller: MFS high-flow oversized
Casing d Inlet: re-profiled for to accommodate the new impeller oversized
Thrust bearing: 360° thrust bearing
Turbine impeller: high-flow oversized
Turbine casing: re-profiled for ly to accommodate the new impeller oversized
Balancing: 150,000 rpm on a Cimat VSR test bench
The Stage 3 is fitted on both the compressor and turbine sides. The oversized impellers require the respective housings to be re-profiled. This configuration may alter the turbo’s flow rate and behaviour; its operation depends on the overall engine set-up.
What is a hybrid turbo?
A hybrid turbo is based on a turbocharger architecture adapted for to accommodate internal components that differ from the d original configuration. Depending on the stage of the upgrade, the modifications may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system and balancing.
The aim is d to adapt the compression capacity and air flow d to the requirements of the modification. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the wheels, the machining of the housings and the overall coherence of the unit are decisive.
MFS compressor wheel: standard or ‘ Performance ’?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This is d ‘a manufacturing process which, on its own, does not guarantee an increase in d air flow. A standard MFS wheel may retain a geometry equivalent to that d of the original.
On this product, the high-flow MFS impeller is described as a forged aluminium impeller, which is lighter, larger and taller than the d'original, with an advertised 15 per cent increase in compression capacity. Depending on the upgrade package chosen, it can also be oversized and fitted with a re-profiled housing.
A standard MFS impeller can be just as shiny as an MFS ‘ Performance ’ impeller. It is not its appearance that determines its performance, but its geometry and its ability to move more d air. A higher airflow can contribute to an increase in power when the engine tuning is correctly adapted, though it does not in itself guarantee results.
Why does the geometry of the blades influence the air flow rate d?
The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour and the amount d of air it can move under certain conditions.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine management system. A larger impeller therefore does not automatically guarantee a better result and may alter the response time as well as the range d of optimal operation.
Reliability and balancing of the hybrid turbo
The 360° bearing stop, featured on the three documented stages, helps to distribute axial forces around the axis. It does not eliminate the need d for proper lubrication or compliance with fitting conditions.
Each unit undergoes d'high-speed balancing at 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses on the rotor, but it does not protect the turbocharger against insufficient lubrication, contamination or incorrect installation.
Engine remapping and tuning
The engine management system must be adapted for to make the most of this hybrid turbo’s characteristics. The mapping, boost pressure, fuel injection, exhaust and cooling systems must be checked or adjusted depending on the level of tuning.
The wastegate must be adjusted when remapping the ECU. The clutch, gearbox and other stressed components must also be checked depending on the vehicle and the desired outcome. No final power output can be guaranteed without a coherent engine configuration.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Before fitting, 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 all pipes.
Check the inlet and ensure that no foreign objects can reach the compressor. Carry out priming in accordance with the applicable recommendations and follow the manufacturer’s instructions.
A lubrication fault that is not rectified may result in the turbocharger failing again.
How do you identify the correct turbo?
Check the part number engraved or marked on the original turbo d, then compare it with the OEM and manufacturer part numbers in this data sheet.. Also check the make, model, generation, body style, engine type, power output at hp, theYear and the engine code where available.
An identical engine specification does not always guarantee compatibility: there may be several different configurations depending on the vehicle and its production period.
⚠️ 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 legible part number of your original turbo d and the precise vehicle details.
