As mentioned, the LBZ Duramax V8 had an SAE-certified output rating of 360 horsepower and 650 pound-feet of torque, which is an improvement of 50 horsepower and 45 pounds of twist compared to the outgoing LLY Duramax.
The LBZ-specific version of the Garrett GT3788VA checks in a hair smaller than the version found on the LLY, but the LBZ is still capable of producing 500 to 530rwhp before it’s out of air.
Is the Duramax LBZ a good engine?
Overall, the Duramax is an extremely reliable engine and is highly capable. Tuned and upgraded LBZ’s will be less reliable without upgraded pistons and rings, but very rarely do either of these cause issues on stuck LBZ’s. The LBZ’s are widely regarded as the best and most reliable Duramax made.
61mm 6 blade compressor wheel. 61mm 10 blade turbine. Electronics included – vane position sensor and vane solenoid.
How much HP does a LBZ Duramax have? – Related Questions
Why is LBZ so desirable?
The LBZ employed a thicker engine block casting, meatier connecting rods, and a higher pressure common-rail fuel system. This gave it more power and reliability versus any other Duramax to that point.

They are in most instances identified by numbers engraved into the flat machined face in the alloy inlet compressor housing. IHI use the Turbo Spec as the turbocharger part number, they usually use 4 characters, usually two letters and two numbers or 4 letters.
Does a bigger turbo increase HP?
The greater the turbo boost pressure, the greater the engine power. Besides, boosting an engine using a turbocharger does not only help to increase the engine’s horsepower but also its torque.
In terms of expenses, two smaller turbochargers are more efficient than one bigger one. However, some engines require twin-turbo kits for better and more efficient operation. This is related to V-type engines. They work much better together with twin turbochargers.
What happens if your turbo is too big?
Each turbocharger is designed to support a specific range of horsepower and engine displacement. If a turbo is too large for your engine, you will have a lot of turbo lag, and if a turbo is too small for your engine you may not reach your horsepower target.
What kills a turbo?
Anytime a turbocharger ingests something — be it dirt, dust, a shop rag or a bolt left in the intake — it can spell disaster. Unfortunately, outside debris making its way across the blades of a compressor wheel (the intake side) accounts for 80 percent of all turbo failures.

Why do turbos whistle?
What causes turbo whistle? Turbo whistle is the sound of the compressor inside the turbocharger speeding up (also known as ‘spooling up’, which is why it kicks in at the boost threshold (when the turbo starts to kick in) as you accelerate up the rev range.
Not all turbocharged cars need premium gas, but it’s a more common requirement among turbos than other kinds of engines, thanks to the way these engines work. The name turbo comes from the turbine these engines use to inject more air into the air-fuel mixture in the combustion chamber.
What mileage do turbos fail?
The life expectancy of a turbocharger can last between 100,000 – 150,000 miles, but this varies based on each driver’s habits. Ensuring you keep an eye on your mileage and driving style will help you to maximise the life of your turbo.
What wears out on a turbo?
Lack of oil and lubrication – the turbo needs a good flow of clean oil to keep it working properly. It can suffer from a build-up of carbon deposits and contaminants that reduce its effectiveness, and can even cause it to completely break down over time.
