Description

This hybrid turbo for, with the engine codes Opel 2.0 i and 240 hp, is available in three documented tuning levels.. Designed for for installation plug & play on the corresponding models, it is fitted – depending on the tuning stage – with a high-flow MFS compressor wheel, a 360° thrust bearing and appropriate internal modifications.

The specifications listed apply to several versions of the Opel, Astra H and Zafira B. The part number of the original turbo dmust be checked before placing any order.

Available upgrades — Stage 1, Stage 2 and Stage 2+

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

This modification primarily affects the compressor side in order dto adapt the flow rate dto the air. The 360° thrust bearing distributes the axial forces, whilst the rotor balancing is designed to limit vibrations at high speed.

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

The Stage 2 combines a oversized compressor wheel with a reprofiled dintake housing. This modification can increase air flow capacity d, but may also alter the turbocharger’s response depending on the engine configuration.

Stage 2+
Compressor wheel: MFS high-flow oversized
Intake housing d: re-profiled for to accommodate the new impeller oversized
Thrust system: 360° bearing thrust
Balancing: high-speed balancing at 150,000 rpm on a Cimat VSR test bench

This version combines documented modifications to both the compressor and turbine sides of th.. The reprofiling of the housings allows th dto accommodate the oversized impellers, with performance that depends on the engine management system and the overall mechanical configuration.

What is a hybrid turbo?

A hybrid turbo retains an architecture suited to the intended installation whilst incorporating internal modifications. Depending on the upgrade stage, these may involve the compressor and turbine wheels, the casings, the thrust bearing system or the balancing.

The aim is dto adapt the compression capacity and the air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry, dimensions, housings and overall balance are all crucial factors.

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 can retain a geometry equivalent to that of the d’original.

An MFS wheel Performance may feature a geometry specific to the tuning specification. On this product, the wheel shown is made from forged aluminium; it is lighter, wider and taller than the original d, with a claimed 15 per cent higher compression capacity.

A standard MFS impeller can be just as effective as an MFS 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 only be fully utilised with appropriate engine tuning.

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 influence its aerodynamic behaviour. A suitable geometry can move more dair under certain conditions, but a larger impeller does not automatically guarantee better performance and may alter the response time. The result also depends on the casings, the turbine, the boost pressure and the engine tuning.

Reliability and balancing of the hybrid turbo

The documented 360° thrust bearing helps to distribute axial forces. The rotor is balanced at high speed, up to 150,000 rpm on a Cimat VSR test bench, in order to limit vibrations and mechanical stresses. This balancing does not compensate for incorrect installation, inadequate lubrication or the presence dof a foreign object.

Engine remapping and preparation

Adjustments to the mapping and pressure control may be necessary for to make the most of the hybrid turbo’s characteristics. The injection, exhaust, intake air cooling d, transmission and wastegate settings must be checked or adjusted depending on the level of tuning. Simply fitting da hybrid turbo does not, on its own, guarantee a power gain.

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 setting checked. 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 make, model, generation, body style, engine type, power output,Year and engine code.. An identical engine may be fitted with several different turbo set-ups.

⚠️ 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 part number from your turbocharger.
