This hybrid turbocharger is designed for for the following engine specifications: Nissan 2.5 DI documented at. Its specification combines a high-flow MFS compressor wheel, a 360° bearing stop and high-speed balancing, with additional modifications depending on the chosen package.
Its design plug & play allows for external Installation without modification. The documented fitments cover several versions of the Nissan Navara and Pathfinder.
Available configurations — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing system: 360° thrust bearing
Balancing: High-speed at 150,000 rpm on a Cimat VSR test bench
This design enhances compression capacity and air flow d thanks to the high-flow MFS impeller, whilst retaining a configuration designed for direct integration.
Stage 2
Compressor impeller: MFS high-flow oversized
d ’ intake housing: Reprofiled for ccommodate the new impeller oversized
Thrust bearing system: 360° thrust bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
Stage 2 is fitted with a compressor impeller oversized and a reprofiled intake casing d. This combination aims to adapt the air passage d to the impeller’s new geometry, without prejudging the engine’s final power output.
Stage 3
Compressor impeller: MFS high-flow oversized
Intake casing d: Reprofiled for to accommodate the new impeller oversized
Thrust bearing system: 360° thrust bearing
Turbine impeller: High-flow oversized
Turbine casing: Reprofiled for ly to accommodate the new impeller oversized
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
Stage 3 modifies the compressor and turbine sides. Resizing the impellers and re-profiling the housings can alter the air flow rate d, the turbo’s behaviour and its response time depending on the engine configuration.
What is a hybrid turbo?
A hybrid turbo is based on a turbocharger architecture designed for to accommodate internal components that differ from the d original configuration. Depending on the upgrade stage, 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 the d air flow. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel, but by its overall geometry and mechanical modifications.
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 airflow d. A standard MFS wheel may retain a geometry equivalent to that d of the original.
An MFS wheel Performance has a geometry tailored to the tuning objective. On this product, the wheel shown is made of forged aluminium; it is lighter, larger and taller than the d original. It is specified for to provide 15 per cent additional compression.
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 contribute to power output with the appropriate engine tuning, though it does not, on its own, 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 volume d of air displaced under certain operating conditions.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine set-up. A larger impeller does not automatically guarantee better performance and may alter the response time as well as the range d of optimal operation.
Reliability and balancing of the hybrid turbocharger
The documented 360° thrust bearing helps to distribute the axial forces exerted on the rotating assembly. It does not, however, replace d'proper lubrication, d'careful installation and compliance with the operating conditions d'the turbocharger.
The rotor undergoes d high-speed balancing at 150,000 rpm on a Cimat VSR test bench to minimise vibrations and mechanical stresses. This balancing does not protect against incorrect installation, inadequate lubrication or the presence d of a foreign object.
Engine remapping and preparation
Operating d'a hybrid turbo requires appropriate engine management. The mapping, boost pressure and wastegate setting must be checked during remapping. Depending on the level of tuning, the fuel injection, exhaust system, intake air cooling d, clutch or gearbox may also require checking or adjustment. The turbo alone does not guarantee a power gain.

Fitting advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication circuit, as well as the oil supply and return d. Check that the pipes are clean, the inlet and that there are no 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 turbocharger failure.
How do you identify the correct turbo?
Check the turbo’s part number d, the original, OEM and manufacturer part numbers, as well as the make, model, engine type, power output,Year and engine code.. An identical engine type does not always guarantee compatibility between two 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 specification sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, please contact us with the part number found on your turbocharger.
