Description

This hybrid turbo for, powered by a 2.0 VCDI engine, is available in three distinct tuning levels.. Depending on the tuning package chosen, the modifications relate to the MFS compressor wheel Performance, the casings and the turbine wheel, featuring a 360° bearing thrust ring and documented high-speed balancing.

The available configurations relate to the Chevrolet Cruze Diesel from 2009 in versions 123, 125 and 150 hp. Compatibility must always be confirmed using the original turbocharger part number d.

Available upgrades — Stage 1, Stage 2 and Stage 3

Stage 1
Compressor wheel: MFS high-flow
Bearing thrust: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench

This configuration uses an MFS compressor impeller designed to adapt the air flow rate d whilst retaining the mechanical configuration documented for for this stage. The 360° thrust bearing helps to distribute the axial forces applied to the rotor more evenly.

Stage 2
Compressor impeller: MFS high-flow oversized
d intake housing: re-profiled for accommodate the new impeller
Bearing thrust ring: 360°
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench

Stage 2 combines a oversized compressor impeller with a reprofiled housing d'admission. This modification is designed to correctly accommodate the new impeller and to increase the compressor’s air displacement capacity d.

Stage 3
Compressor impeller: MFS high-flow oversized
d intake housing: re-profiled for to accommodate the new impeller
Bearing thrust ring: 360°
Turbine impeller: high flow oversized
Turbine casing: re-profiled for ly to accommodate the new impeller
Balancing: high-speed at 150,000 rpm on a Cimat VSR test bench

This preparation includes modifications to both the compressor and turbine sides. The re-profiling of both housings allows d'the oversized impellers documented here to be fitted. The final performance, however, depends on the overall engine configuration and its settings.

What is a hybrid turbo?

A hybrid turbo is based on a turbocharger architecture adapted to accommodate modified internal components. Depending on the upgrade stage, the modifications may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system and the balancing of the rotor.

The aim is d to adapt the compression capacity and air flow rate d to the requirements d of an engine upgrade. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel: the aerodynamic profiles, dimensions and adaptation of the casings are also crucial.

MFS compressor wheel: standard or ‘ Performance ’?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This technology describes the manufacturing process and does not, on its own, guarantee an increase in air flow rate d. A standard MFS wheel can retain a geometry equivalent to that of the d original.

An MFS wheel Performance can be given a geometry tailored to the intended modification. For this product, the wheel is described as being made of forged aluminium, lighter, larger and taller than the d original, with a claimed 15 per cent increase in compression capacity. Its exact dimensions are not specified.

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. A higher airflow can help to generate more power when the engine management system and peripheral equipment are suitably configured.

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 operating conditions.

The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure, as well as the engine set-up. A larger impeller does not automatically guarantee better performance and may alter the response time or the range d'within which the turbo operates optimally.

Reliability and balancing of the hybrid turbo

The 360° thrust bearing, featured in the three documented stages, distributes axial forces over a wide surface area. It helps the bearing adapt to the stresses of the tuning without making the turbocharger insensitive to poor lubrication or incorrect fitting.

Each stage undergo 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 during operation.

Engine remapping and tuning

The engine management system must be adapted for to make full use of the characteristics d of a hybrid turbo. The wastegate must be adjusted during the ECU remapping.

Depending on the level of tuning, the fuel injection, exhaust system, intake air cooling d, boost pressure, clutch or gearbox may also require checking or adjustment.. Fitting the turbo alone does not guarantee a power increase.

Installation advice

⚠️ WARNING — IMPORTANT BEFORE INSTALLATION

Identify and rectify the cause of the previous fault. It is essential to check the lubrication circuit as well as the oil supply and return d.

Check that the pipes and the inlet are clean and free from foreign objects. Carry out priming in accordance with the applicable recommendations and follow the vehicle manufacturer’s instructions.

Failure to rectify a lubrication fault may result in further damage to the turbocharger.

How do you identify the correct turbo?

Check the part number marked on the original turbo d and 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, as there may be several different set-ups for for the same vehicle.

⚠️ 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 you are unsure about your fitment, please contact us with the part number from your turbocharger.

However, a fault that appears to be turbo-related may also stem d from a lubrication issue, d from contaminated oil, d from a foreign object, from the intake or exhaust systems, or d from another engine peripheral component.

It is therefore important to investigate the cause of the fault before fitting a new turbo or a new Cartridge.
