The 12-valve Cummins engine has earned legendary status among diesel enthusiasts, known for its robust build, impressive torque, and remarkable longevity. But finding a brand-new 12-valve isn't as simple as walking into a dealership. This is where the allure of 12-valve Cummins crate motors comes in. These pre-assembled engines offer a shortcut to the power and reliability this iconic engine provides, perfect for rebuilds, swaps, and custom projects. This article delves deep into everything you need to know about 12-valve Cummins crate motors.
What is a 12-Valve Cummins Crate Motor?
A 12-valve Cummins crate motor is a completely assembled engine, ready for installation. Unlike buying parts individually and assembling the engine yourself, a crate motor arrives as a single unit, tested and ready to go. This significantly simplifies the process, reducing the time and expertise required for installation. These engines often come with varying horsepower and torque ratings, depending on the specific model and modifications.
Where Can I Find a 12-Valve Cummins Crate Motor?
Unfortunately, finding genuine, brand-new 12-valve Cummins crate motors directly from Cummins is difficult, if not impossible. Cummins' focus has shifted to newer engine models. However, numerous reputable engine rebuilders and parts suppliers offer remanufactured or rebuilt 12-valve Cummins engines that are essentially equivalent to crate motors. These are typically sourced from used engines that are meticulously disassembled, inspected, and rebuilt using high-quality parts. Thorough research is crucial to identify a trustworthy supplier with a proven track record.
What are the Benefits of Using a 12-Valve Cummins Crate Motor?
- Time Savings: The biggest advantage is the significant time saved compared to sourcing individual parts and rebuilding an engine.
- Reliability: Remanufactured engines undergo rigorous testing, ensuring reliability and reducing the risk of premature failure.
- Warranty: Reputable suppliers often provide warranties on their remanufactured engines, offering peace of mind.
- Consistent Performance: A crate motor offers consistent performance characteristics, unlike engines assembled from various used parts of uncertain quality.
- Ease of Installation: A completely assembled engine simplifies the installation process, especially for those without extensive mechanical experience.
What Horsepower and Torque Can I Expect?
The horsepower and torque output of a 12-valve Cummins crate motor will vary depending on the specific model and any modifications. Stock 12-valve engines typically produced between 160 and 230 horsepower and substantial torque in the 400-600 lb-ft range, depending on the year and application. However, with modifications, these numbers can be significantly increased. It's crucial to clarify the exact specifications with the supplier before purchasing.
What are the Common Applications for 12-Valve Cummins Crate Motors?
12-valve Cummins engines are highly versatile and popular for several applications:
- Truck Swaps: A frequent use is swapping a worn-out engine in a pickup truck or heavy-duty vehicle.
- Custom Vehicle Builds: These engines are favored in custom builds, offering a powerful and reliable foundation.
- Marine Applications: Their robust nature makes them suitable for marine applications.
- Industrial Equipment: Their reliability and power make them a good fit for various industrial applications.
How Much Does a 12-Valve Cummins Crate Motor Cost?
The cost of a remanufactured 12-valve Cummins engine varies significantly based on the condition of the core engine used, the level of rebuild (major vs. minor), any added modifications, and the supplier. Expect to invest a substantial amount, ranging from several thousand dollars to upwards of $10,000 or more, depending on the specifics.
What Should I Look for When Buying a 12-Valve Cummins Crate Motor?
- Reputation of the Supplier: Choose a reputable supplier with positive reviews and a proven track record.
- Warranty: Ensure the supplier offers a comprehensive warranty.
- Specifications: Confirm the engine's exact horsepower, torque, and specifications.
- Testing: Inquire about the testing procedures performed on the remanufactured engine.
- Parts Used: Ask about the quality and origin of the parts used in the rebuild.
The 12-valve Cummins engine remains a highly sought-after powerplant, and while finding a new crate motor directly from the manufacturer is unlikely, many quality options exist through reputable rebuilders. Careful research and due diligence are essential to secure a reliable and powerful engine for your project. Remember to always check with your chosen supplier for the most up-to-date information on availability and pricing.
