This hybrid turbo is designed for the Bmw 318d 2.0 TD with 115 hp. Its specification is based on a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing, with additional modifications depending on the chosen upgrade package.
Designed for for installation plug & play without any modifications to the mounting, it is suitable for the Bmw E46 Series 3 Compact and Touring applications documented below.
This modification primarily affects the compressor wheel in order d to adapt the compression capacity and the air flow rate d. Its operation must remain consistent with the engine management system and the vehicle’s other components.
oversized ’s compressor impeller requires the intake housing to be re-profiled d. This combination aims to alter the compressor’s air displacement capacity d, though it does not, on its own, guarantee a specific power output.
The Stage 3 combines modifications to the compressor side with a oversized turbine wheel and a re-profiled. turbine housing. This configuration alters the aerodynamic balance of the turbocharger and may influence both its flow rate and response time depending on operating conditions d.
A hybrid turbo utilises a turbocharger design adapted for to accommodate internal components that differ from the original configuration d. Depending on the upgrade stage, the modification may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing or even the balancing of the rotor.
The aim is d to adapt the compression capacity and air flow d to the requirements d of an engine upgrade. However, a hybrid turbo is not defined solely by the appearance of its impeller: the geometry, dimensions, machining of the housings and the combination of components are all crucial.
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 rate d. A standard MFS wheel may retain a geometry equivalent to that of the d original.
An MFS wheel Performance is characterised by a geometry tailored to the tuning objective. For this product, the MFS wheel is documented as being lighter, larger and taller than the d original, with an advertised 15 per cent increase in compression capacity. The versions Stage 2 and Stage 3 use a compressor wheel oversized.
A standard MFS impeller can be just as efficient 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 flow rate can contribute to power output when the engine is correctly tuned, though it does not in itself guarantee results.
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 its ability to move air depending on the operating speed.
The result also depends on the housings, the turbine wheel, the boost pressure and the engine set-up. A larger wheel therefore does not automatically guarantee better performance in all conditions and may alter the turbocharger’s response time.
The 360° bearing stop, documented at each production stage, helps to distribute the axial forces exerted on the rotating assembly. It does not, however, d'replace the need for proper lubrication or d'correct installation.
The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses, but does not protect the turbocharger against insufficient lubrication, contamination or incorrect installation.
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 when remapping the ECU.
Depending on the level of tuning, it is also advisable to check or d'adjust the fuel injection, exhaust system, cooling, boost pressure and, if necessary, the transmission. Fitting d'a hybrid turbo does not automatically guarantee a power gain without appropriate tuning.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d installing the turbo.
Check the lubrication system, the oil supply and return lines, and ensure all pipes are clean d.
Check the intake and ensure there are no foreign objects. Prime the system in accordance with the applicable guidelines and follow the manufacturer’s instructions.
A lubrication fault that is not rectified may lead to the turbocharger failing again.
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, mountingYear and engine code where available. 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 specification sheet. An identical engine specification does not always guarantee compatibility.
If you are unsure about the identification or fitment, please contact us before ordering.

A single engine type may have been fitted with several different turbochargers depending on theYear, power output, engine version or technical evolution.. The application alone is therefore not always sufficient for to accurately identify the correct turbo.
Before ordering, note down the part numbers shown on the identification plate d of your old turbocharger. This may be d an OEM part number or d a part number from the turbo manufacturer.
Compare these part numbers with those listed on our product pages.. If in doubt, our team can help you verify the part number you are looking for before you place your order.
A loss of power, an unusual whistling noise, oil consumption d, abnormal smoke or poor engine performance may be linked to a turbocharger fault.
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.
Since 2012, ALFI TURBO has been assisting private individuals and professionals in identifying and replacing turbochargers.
A turbocharger failure may be the result d of another engine problem. Before fitting d a new turbo or Cartridge, identify and rectify the cause of the original fault to d avoid d damaging the new part.
