But just how much horsepower can a stock Duramax handle? In this FAQ-style blog post, we’ll answer that question and address some other commonly asked questions about Duramax engines.

How often do Duramax injectors go bad

Duramax injectors are built to be robust and durable, but like any mechanical component, they can wear out over time. On average, Duramax injectors can last between 100,000 and 200,000 miles before needing to be replaced. However, proper maintenance and quality fuel can extend their lifespan. So, take care of your Duramax, and those injectors will keep chugging along!

How much do injectors cost for a Duramax

Replacing injectors can be an expensive endeavor. On average, the cost of a single Duramax injector ranges from $200 to $500, depending on the model year and whether you’re buying an OEM or aftermarket injector. If multiple injectors are failing, the cost can multiply quickly. It’s essential to keep this in mind when budgeting for Duramax ownership.

How much horsepower can a stock Allison 1000 handle

The Allison 1000 transmission, paired with the Duramax engine, is known for its strength and reliability. In stock form, this transmission can handle up to 350 horsepower and 700 lb-ft of torque. However, it’s worth noting that pushing the limits of a stock transmission for an extended period may lead to premature wear and failure. So, if you’re contemplating going beyond stock power levels, it’s wise to consider upgrading your transmission for optimal performance and longevity.

How much horsepower does a 2002 Duramax have

Ah, the legendary 2002 Duramax! This model year is equipped with the LB7 engine, famous for its power and reliability. Straight from the factory, the 2002 Duramax delivers an impressive 300 horsepower and a whopping 520 lb-ft of torque. It’s no wonder why this engine has earned such a dedicated following over the years.

What is high mileage for a Duramax

Duramax engines are built to last, so high mileage is not unusual for these beasts. In fact, anything over 200,000 miles is considered high mileage for a Duramax. However, with proper maintenance, some owners have managed to push their engines well beyond the 300,000-mile mark. Remember, regular oil changes, fuel filter replacements, and other scheduled maintenance are key to keeping your Duramax running smoothly for the long haul.

Is LMM or LML better

When it comes to comparing Duramax engines, the LMM and LML are both powerhouses in their own right. The LMM engine, introduced in 2007, offers excellent reliability and fuel efficiency. On the other hand, the LML engine, which made its debut in 2011, boasts improved power and emissions control. Ultimately, the choice between the LMM and LML comes down to personal preference and specific needs. Both engines have their strengths, so you can’t go wrong with either one!

What year Duramax has injector problems

The 2001 to 2004 model years of the Duramax engine, also known as the LB7, have gained a reputation for injector problems. This issue was primarily due to design flaws that resulted in potential water contamination and, consequently, injector failure. However, it’s essential to note that GM extended the warranty on LB7 injectors to cover this issue, providing some peace of mind to owners. Overall, later model years of the Duramax engine have addressed and resolved the injector problem, so rest assured that newer models have improved reliability.

So, how much horsepower can a stock Duramax handle? In most cases, a stock Duramax can comfortably handle around 300 to 350 horsepower. However, it’s worth remembering that pushing your engine to its limits for extended periods may cause premature wear and decrease overall reliability. If you’re looking to increase your Duramax’s performance, consider exploring aftermarket upgrades or consulting with experts who can guide you in maximizing both power and durability. And remember, taking care of regular maintenance is crucial to keeping your Duramax happy and healthy for miles to come!
