After having been founded in 1936, by Cliff Garrett, the Garrett Corporation (Garret Advancing Motion Genuine Equipment Turbochargers) grew to become the world’s largest turbocharger manufacturer. Since its inception, with its involvement in racing, Garrett has led the way in engine boosting design and development while using the racing environment as a testing ground and research laboratory for its ever improving and advanced design concepts.

If you have not noticed, Garrett Turbochargers strongly promotes the importance of original, genuine equipment and for good reason. They have delved into researching failed, copycat turbochargers and discovered interesting data. Recent product analyses in comparisons between original equipment Garrett turbos and copy, remanufactured, non-original equipment turbos found that the Garrett original quality turbos deliver better value in performance, fuel efficiency, reliability and longevity.

Given all the effort Garrett put into quality comparison, you can take their mantra to heart when they say, “Insist on Garrett.”

Garrett further says…

When it’s time to replace your turbocharger, don’t take risks. When your turbocharger is spinning at 300,000 rpm, and operating up to 1050 degrees Celsius, almost the same isn’t good enough.

Consistent Performance, Consistent Calibration & Consistent Value With Garrett Turbochargers

Garrett says, “Accept no substitute“, and they mean it. With Garrett turbos you get consistent performance, consistent calibration and consistent value while dodging the risks associated with settling for the substandard quality of copy turbos. The concern with copy turbos is that they can fail within hours after having been installed. That is not good. Bearing problems are the most common shortfall of copy turbochargers and turbine-housing-to-center-housing connecting bolts weaken, leading to mechanical damage while allowing fuel and oil leaks which can contaminate catalytic converters and diesel particulate filter (DPF) systems. Important reasons for accepting no substitutes, for sure!

Garrett Turbocharger Repair, Replacement & Install

If you are running a copy turbo and have noticed you are experiencing problems, Cummins Automotive & Diesel Service can look at your engine and turbo system to determine if you are at risk for future, more serious complications. Cummins Automotive & Diesel Service can perform system checks to look for possible conflicts your copy turbo has with your engine’s management system.

Cummins Automotive & Diesel Service can test to see if you have increased or too high a level of emissions, air flow that is too low or pressure that is too low. These can be contributing factors to why you may have noticed poor response and poor, overall performance.

If you have noticed excessively high temperatures, you may or may not know that this can lead to damage of both the turbo and the engine. Cummins Automotive & Diesel Service can analyse your fuel/air mixture to see if the system is running with an overly high diesel fuel/air mixture, a leading cause of excessive operating temperatures.

If you have experienced compressor wheel bursting, turbine wheel bursting or turbo overspeeding, you may have pressure that is out of optimal range. Cummins Automotive & Diesel Service can check your turbo pressure readings which can reveal the proper repair or service needed so your engine and turbo can be repaired according to manufacturer recommendations or your turbo can be replaced with a new turbo installation before further damage is sustained by the engine and turbocharger.

Excessive boost pressure can cause physical damage to the engine. Cummins Automotive & Diesel Service can check your boost pressure. If it is out of range, they can either service and repair your existing turbocharger or install a replacement, original quality Garrett turbo.

Independent Lab Turbocharger Testing Results

See the Garrett turbocharger, independent testing results in PDF document format.

Did you know Independent laboratory tests have shown as much as a 40% performance gap between genuine Garrett aftermarket turbos and copy turbos? It is true. 2016 independent lab testing, conducted at Millbrook Proving Ground in the United Kingdom, showed results revealing significant differences between Garrett genuine, original equipment (OE) fit turbos and copy turbos. It compared Garrett, original brand to German, Spanish and Chinese brand copy turbos.

The results are worth standing up and paying attention to from both a performance perspective and an emissions perspective. Engines using copy turbochargers had low-end torque that was diminished by an amount of between 15% and 40%. CO2 emissions from copy turbochargers were nearly 3% greater. Nitrogen Oxide (NOx) emissions from engines using copy turbochargers were between 8% and 28% higher.

If you are running a copy turbo, you can run the risk of decreased performance and increased emissions. Less low-end torque requires an engine to work at a higher band at lower speeds which means, in the initial acceleration phase, it will use more fuel. Copy turbos put you at risk of higher fuel expenses. Couple that with higher CO2 and NOx emissions and you are not only paying more to move down the road, but you are making the environment pay more for your vehicle to move down the road and you risk the possibility of failing an emissions test which can result in being denied the right to drive on public roads.

Let Cummins Automotive & Diesel Service take a look at your turbocharger. If your turbo is contributing to an engine and fuel system that is delivering low performance or high emissions, Cummins Automotive can install a Garrett quality turbo.

Take advantage of Garrett original quality, original equipment. Drive with the knowledge and peace of mind that you are driving with a turbo of world class assembly quality which statistically provides four times the whole life value of copies. Your turbo will provide outstanding reliability with precision, OE parts that are of an industry standard and intricate calibration that are designed to contain compressor wheel bursts and turbine wheel bursts.

A Garrett Turbo For Every Application

Garrett turbo has a turbocharger for nearly every size of diesel and gasoline light vehicle engine from 0.6 liter power units to 6.7 liters. Garret’s turbochargers for heavy duty applications, including heavy trucks and off-highway equipment, produce boost for engines with power ratings from 60hp to a mighty 4000hp.

The Garrett turbocharger designs take in over 3,500 models, from their free floating and wastegate turbos to their exclusive Variable Nozzle Turbine (VNT) technology, Variable Geometry Turbo and Two Stage systems. Many turbo models include advanced actuation systems for integrating the turbo control with the vehicle’s ECU.

The Garrett turbo systems, including the Variable Geometry Turbo (VNT) configuration, Wastegate designs and the Two Stage design, leverage engineering accomplishments in aerodynamics, bearing materials and electric actuation to set high marks for performance and reliability.

Garrett Downsized High Temperature Variable Geometry Technology (VNT) Turbochargers For Diesel Engines

Garrett’s variable geometry VNT technology has been applied to more than 70 million diesel engines in the last three decades. The turbo design helps fleet managers and truck operators boost car and light commercial vehicle engine performance, increase fuel efficiency, reduce emissions and enhance drivability.

With VNT turbochargers, engine efficiency can be optimized because their platforms are designed to operate at the higher temperature of 870°C rather than the conventional 830°C whereby it converts the thermodynamic energy in the exhaust gas to boost engine performance, deliver more power and provide better responsiveness while also improving fuel efficiency and reducing NOx emissions. These innovations in aerodynamics and super efficient bearings allows the Garrett VNT turbos to deliver a 5% improvement in low-end torque which improves acceleration and effectively recirculates exhaust gas.

This is an industry win-win that provides daily drivers, truck operators, fleet managers and marine and construction operators the ability to meet stringent emissions standards and benefit from superb performance.

Garrett Small Wastegate Turbochargers For Diesel Engines

Garret’s small wastegate turbos provide improved aerodynamics, fuel efficiency and emissions control while maintaining unparalleled performance. The wastegate design zeroes in on low-end torque and transient response with a lighter overall weight. The small wastegate turbo is designed for diesel engine sizes 0.8 Liters to 3 Liters and corresponding power ratings ranging from 30kW to 120kW.

Garrett Two Stage Turbochargers For Diesel Engines

Garrett Two Stage Parallel Turbochargers For Diesel Engines

For diesel engines sized 2.0 Liters and bigger, the Garrett Two-Stage parallel turbo system configures two turbos, working in sequence, to deliver significant gains in power and torque.

Garrett Two Stage Serial Turbochargers For Diesel Engines

Garrett’s Two Stage serial turbo for diesel engines compounds the benefits of turbocharging by using two turbos configured in series. Two turbochargers arranged in series helps improve transient performance, offers better low-speed torque and optimizes fuel efficiency for daily drivers and fleet or truck operators. This technology allows engines to be downsized while increasing performance which is an overall savings for drivers and operators.

The Two Stage serial turbochargers are used with an array of engine sizes from single Liter vehicles to 64 Liter mining equipment engines. The majority of Two Stage turbos are installed on autos and trucks with engine sizes of 1.6 Liters to 3 Liters.

Turbo Diagnostics Before Turbocharger Replacement

Most turbocharger problems result from a handful of causes. Cummins Automotive & Diesel Service knows how to recognize the symptoms of these issues and link them with causes that will help you save downtime and money.

If you think your vehicle has a damaged turbo or a problem related to the turbocharger, Cummins Automotive & Diesel Service recommends carrying out diagnostic testing before replacing a turbo because turbocharger damage can often be a symptom of an underlying problem rather than the cause itself.

Cummins Automotive & Diesel Service will complete a diagnostic check before replacing your turbocharger. This can save you money because symptoms such as a lack of power, noisy performance, excessive smoke or excessive oil consumption could result from many other causes such as restricted or plugged air filters, faulty fuel injectors, a lubrication problem or a damaged exhaust system.

Engine Performance Symptoms May Indicate Problems Other Than Turbo Problems

Lack Of Power

If your truck or auto lacks power, Cummins Automotive & Diesel Service can check the condition of the filter, hoses and pipes, can check the fuel injection system for correct adjustment and condition and can check that the exhaust system, the catalyst and the diesel particulate filter (DPF) are not blocked or damaged.

Noisy Performance

If your truck, tractor, pickup or car is operating with more noise than is normal (noisy performance), Cummins Automotive & Diesel Service can check for loose or damaged pipework and support brackets while verifying that the connections are good and properly sealed and can check for possible leaks or cracks in the intercooler.

Excessive Smoke Or Excessive Oil Consumption

If your tractor trailer, semi truck, pickup, construction machinery or car is showing excessive smoke or excessive oil consumption, Cummins Automotive & Diesel Service can check the air filters for restricted or blocked airways, can check to determine whether or not the oil in the engine complies with the vehicle manufacturer’s recommended oil specifications, can check that the oil drain pipe is clean and free of restrictions, can test for excessive pressure in the engine crankcase, can check the function of the engine breather system, can check the condition of hoses and joints and can check for oil or carbon deposits on the exhaust manifolds or in the turbine; both of which are signs of a lubrication problems in the engine block.

Diagnostic Troubleshooting Can Determine Reasons For Turbocharger Damage When There Is No Obvious Cause

If your turbocharger has sustained damage and you cannot determine an obvious cause, Cummins Automotive Diesel & Service have quality specialists who can carry out extensive troubleshooting. With diagnostic troubleshooting, the Cummins Automotive technician may be able to determine if your turbocharger damage was caused by foreign objects, lack of lubrication, oil contamination or by overspeeding and excessive temperatures.

Foreign Objects Can Be A Cause Of Turbocharger Damage

The technician can troubleshoot compressor or turbine wheel damage to determine if it was caused by small objects, at high speed, entering the turbine or compressor housing, leading to an imbalance that can damage the compression wheel or the nozzle assembly of the turbo.

Lack Of Lubrication Can Be A Cause Of Turbocharger Damage

The Cummins Automotive & Diesel Service technician can troubleshoot turbo fatigue cracking and material transfer to determine if it was caused by metal friction from bearing material transfer and high temperatures resulting from oil inlet supply restrictions, misaligned gaskets, liquid gasket failure or poor quality lubricants.

Oil Contamination Can Be A Cause Of Turbocharger Damage

The technician can troubleshoot turbo bearing system damage that can be caused by a high concentration of carbon suspended in oil, can troubleshoot bearing system damage caused by extended oil change intervals or neglected maintenance. If you recently had a major engine overhaul, the Cummins Automotive & Diesel Service technician can troubleshoot turbo bearing system damage to determine if it was caused by a steel shot that was suspended in the oil. The technician may find worn or scored bearings, bearing material that has transferred to the shaft, or steel and other metal particles in the oil, all of which can be causes of shaft scoring and disintegration impacts.

Overspeed & Excessive Temperature Can Be A Cause Of Turbocharger Damage

The Cummins Automotive & Diesel Service technician can troubleshoot turbo damage to determine if it was caused by overspeeding and excessive temperatures. The technician may determine the turbo has operated at a level beyond its vehicle manufacturer specs and designed parameters. Poor maintenance, maintenance neglect, engine malfunction or performance upgrades that push operating levels beyond component or engine specifications can push turbo rotating speeds beyond its designed operating limit, which can cause fatigue or failure of the compressor wheel and turbine wheel.
