This hybrid turbocharger for, with the following specifications: Bmw 2.0 D and 163 hp, is available in three performance levels.. Each version is fitted with a high-flow MFS compressor wheel Performance, a 360° bearing stop and high-speed balancing on a Cimat VSR test bench.
It is designed for the Bmw Series 1, Series 3 and Series 5 applications listed in this data sheet. Its design plug & play allows for external Installation without modification on compatible applications, subject to verification of the original turbocharger part number d.
Available conversions — Stage 1, Stage 2 and Stage 2+
Stage 1
Compressor wheel: MFS Performance high-flow
Dimensions: 38.35 / 51.00 mm
Blade configuration: 11+0
Bearing stop: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
This set-up utilises an MFS Performance impeller designed for dapt the air flow rate dof the compressor. Its final performance depends on the engine management system and all associated components.
Stage 2
Compressor impeller: MFS Performance high flow rate oversized
Dimensions: 43.01 / 56.02 mm
Blade configuration: 6+6
dintake housing: re-profiled for ly to accommodate the new impeller
Bearing thrust: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
The Stage 2 combines a oversized impeller with a dintake casing, reprofiled. These modifications are designed to optimise airflow and compression, though they do not, on their own, guarantee a specific power output.
Stage 2+
Compressor impeller: MFS Performance high-flow oversized
Dimensions: 56.00 / 60.62 mm
Blade configuration: 6+6
dintake housing: re-profiled for ccommodate the new impeller
Bearing stop: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench
The Stage 2+ is fitted with a larger impeller and a modified intake dhousing. An increase in size may alter the available flow rate, response time and the range dat which the turbocharger operates optimally.
What is a hybrid turbo?
A hybrid turbo retains a turbocharger architecture designed for accommodate modified internal components. Depending on the stage, the modification may involve the compressor wheel, its dimensions and the geometry of its blades, as well as the machining of the housing designed to house it.
The aim is dto adapt the compression capacity and air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its impeller: the balance between the compressor, the turbine, the housings, the boost pressure and the engine management system remains 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 d. A standard MFS wheel can retain a geometry equivalent to that dof 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 this product, the dimensions and blade configurations vary depending on the package selected. Higher airflow can contribute to power output with the appropriate engine tuning, though this does not guarantee results.
Why does the blade geometry 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. 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 mapping. 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° bearing stop documented across the three stages helps to distribute the axial forces to which the rotating assembly is subjected. It does not eliminate the need d’for proper lubrication or d’for correct installation.
Each engine build benefits dfrom 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 does not protect against contamination, a fault din the oil or incorrect installation.
Engine remapping and preparation
Adjustments to the engine mapping and boost pressure management may be necessary for to make the most of the hybrid turbo’s characteristics. Depending on the level of tuning, the fuel injection, exhaust system, intake air cooling d, clutch or gearbox must also be checked. The wastegate must be adjusted during fitting and remapping. No power gain is automatic without a coherent configuration.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d’installing the turbo.
dCheck the lubrication system, the oil supply and return lines, and ensure all pipes are clean. Also check the intake for any foreign objects.
Carry out the priming procedure in accordance with the applicable recommendations and follow the manufacturer’s instructions. The wastegate setting and mapping must be adapted to the chosen set-up.
Unresolved lubrication issues may lead to further turbocharger failure.
How do you identify the correct turbo?
Check the part number marked on the original turbo d, then compare it with the OEM and manufacturer part numbers in this datasheet.. Also check the make, model, generation, body style, engine type 2.0 D , power output 163 hp and theYear. . 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 does not always guarantee compatibility.
If you are unsure about the identification or the appropriate tuning stage for your set-up, please contact us with the full part number of your turbo.
