Navigating the turbocharger market is becoming ever harder. The range of options is wide and the differences between individual products may seem minimal at first glance. Sometimes, on the other hand, you may be surprised by a large price disparity. We have prepared a guide for you with all the information you need to make the right choice.
An original turbocharger is the part that was fitted to your vehicle directly in OEM production. The manufacturers of such parts are referred to as OEM (Original Equipment Manufacturer). The largest global OEM turbocharger manufacturers include Garrett, BorgWarner, IHI, Mitsubishi, Holset, Continental, BMTS and ČZ, all these brands are available from us.
OE turbochargers are specifically developed for each car manufacturer to precisely meet the technical and performance parameters of a particular vehicle. The original turbo is tuned to fit a specific engine, has gone through long development and thorough testing. Only original products ensure the optimum performance and driving characteristics designed by the car manufacturer.
OEM manufacturers distribute their turbochargers through three main channels:
At an authorized distributor such as us you can choose from three main variants of original turbochargers. Each variant has its justification and proper use.
A brand-new original turbo directly from the manufacturer. The same part used in OEM production or as an OE spare. Full warranty, full OE quality.
Factory remanufactured directly by the manufacturer (Garrett Original REMAN, Holset REMAN, BorgWarner REMAN). Original parts, OE standards, same warranty as new. The most cost-effective original, sold on exchange for an old core.
Turbochargers for modifications and increased performance, for tuning, motorsport and racing specials. Often with ball bearings, higher boost pressure and optimised compressor geometry.
Journal bearings are typical for ordinary turbochargers. They rely on hydrodynamic lubrication, where an oil film is formed between the rotor and the bearing.
Ball bearings (Ball-Bearing) bring significant advantages for high-performance applications:
Up to 15 % faster spool-up compared to journal bearings. The vehicle will not suffer from "turbo lag".
Friction difference of up to 50 % in favour of ball bearings (according to Garrett).
Less oil needed, lower risk of seal leakage. More resistant to short-term oil-supply interruption at start-up.
Supercharged internal combustion engines are still the most efficient drive unit for motor vehicles. The development of turbochargers over the past decades has come a long way, from a simple assembly of a turbine and compressor housing with a basic bearing unit to sophisticated systems with electronically controlled actuators.
The simplest type of control. The flap diverts exhaust gases past the turbine to prevent the desired boost pressure being exceeded. Controlled by boost pressure from the compressor.
A system of variable vanes or a sliding wall in the turbine housing. It changes flow geometry according to engine RPM, high efficiency across a wide operating range.
Rotary Electronic Actuator and Simple REA, electronic controls with a stepper DC motor for high accuracy and efficiency. Applied to turbos for passenger cars, trucks and mining machines.
A combination of two turbochargers (a small one for low RPM, a large one for higher). Eliminates turbo lag, optimises output across the full RPM range. Typical for more powerful modern engines.
Gradual engagement of multiple turbochargers depending on current engine load. Often combined with ball bearings for extreme performance.
The latest generation of turbochargers with an integrated electric generator. Takes hybrid powertrains and the combustion engine itself to the next level.
Turbocharger labelling follows no unified format. Every manufacturer has its own numbering system and type of label. This is why it is often hard to navigate, and unfortunately sellers of non-original parts mostly profit from it.
You will find it stamped on your turbocharger's label. This number is the key to identifying the specific type, even if there are several different designations for the same part depending on the distribution channel.
Be especially careful with sellers advertising turbos under labels such as "REBUILD GARRETT 751851", "TURBO GARRETT OCTAVIA, 751851" etc. These companies may sell rebuilt parts of very variable quality that have little in common with the original. The main indicator is usually a significantly lower price.
Most turbocharger failures are caused by lubrication-related problems, contaminated engine oil, clogged oil galleries or missed service intervals. Correct installation and first start-up therefore determine the service life of a new turbo.
If the original turbo failed due to an engine problem (dirty oil, clogged galleries, faulty injectors), it is essential to remove the cause first. Otherwise the new turbo will fail for the same reason, and the manufacturer's warranty does not cover faults caused by incorrect installation or operation.
As part of our complete care for supercharged engines, in addition to turbochargers we also offer a supplementary range in the fields of cooling, exhaust-gas recirculation and professional installation. All from original OE manufacturers, in top quality and at favourable aftermarket prices.
Since 2010, when we extended our portfolio with BorgWarner Thermal Systems products, we have been an authorized distributor of viscous clutches and fans for engine cooling. We later extended our cooperation to include the BEHR-HELLA Service brand, together we cover the widest possible portfolio of engine thermal-management solutions.
Our offer includes viscous clutches and fans for all types of trucks and commercial vehicles as well as off-highway machinery. We specialise in the following makes:
A fan with a viscous clutch uses limited slip provided by the temperature-dependent viscosity of the fluid inside the clutch. With Visctronic technology the fluid is bypassed using an electromagnetic valve, thanks to this precise regulation the fans deliver an exact cooling output and save up to 9–10 % of fuel compared with older clutch designs.
Robust workmanship and lightweight construction reduce the parasitic load on the engine's crankshaft, which results in higher engine output.
For agricultural vehicles of the CNH group (Case, New Holland) and AGCO (Fendt, Massey Ferguson, Valtra).
We will help you choose the right fan or clutch for your specific application and advise on installation.
As part of our complete care for supercharged engines we also offer original EGR modules and valves from OE manufacturer BorgWarner (WAHLER brand). All products in OE quality and at very competitive aftermarket prices.
As the name suggests, this is exhaust gas recirculation. Through the EGR valve a portion of the exhaust gases is returned to the engine intake. Such exhaust gases contain a minimum amount of oxygen and thus practically do not take part in combustion.
Their presence reduces the combustion chamber volume and also lowers the mixture temperature. All this contributes to lower emissions. EGR is therefore an increasingly common feature of modern engines that helps to meet strict emission standards.
EGR modules for popular vehicles from the Volkswagen group, Audi, Škoda, Volkswagen, Seat.
A wide range of valves for various types of light commercial vehicles and other applications.
Original modules and valves directly from OE manufacturer BorgWarner (WAHLER), the same as used in OEM production.
Correct installation of a turbocharger is absolutely crucial for the trouble-free further operation of your machine. By following the exact procedure you prevent the risk of repeated damage and preserve the correct engine properties. SPECIAL TURBO exclusively brings a practical and effective solution to this issue, JO TECH installation kits.
The kits are available for passenger cars, light commercial vehicles and now also for selected trucks. They contain all the necessary components in one package, saving you time and money.
A syringe with fully synthetic oil certified for the automotive industry. Pre-lubrication is a manufacturer-prescribed procedure, without it the rotor and bearings will be damaged immediately.
Bolts and nuts with increased strength and special surface treatment, resistant to high temperatures (up to 900 °C at the flange) and to corrosion.
A complete set of all gaskets, turbine flange, oil supply and return. Genuine gaskets cannot be replaced by "liquid" sealant without serious risk of failure.
Starting a turbocharger without proper pre-lubrication leads to immediate destructive damage to the bearings and rotor. The manufacturer will not accept such a fault under warranty.
Using substitutes without adequate strength risks cracking and breaking inside the engine, a costly repair and long downtime.
A very common fault due to material fatigue or use of unapproved bolts (low strength, lack of surface treatment).
For 34 years we have been operating on the market as an authorized distributor and service centre of all turbochargers from Garrett, Holset, BorgWarner (KKK and Schwitzer), Mitsubishi, IHI, Continental, BMTS and ČZ, as well as viscous fans from BorgWarner Thermal Systems and Behr-Hella Service.
