The 12-valve Cummins engine enjoys legendary status among diesel enthusiasts. Known for its robust build, impressive torque, and relative simplicity, it's a favorite for everything from heavy-duty trucks to custom projects. But finding a new 12-valve can be tricky. Enter the world of crate motors – pre-assembled engines ready for installation. This article explores the nuances of 12-valve Cummins crate motors, addressing common questions and helping you understand what to expect.
What is a 12-Valve Cummins Crate Motor?
A 12-valve Cummins crate motor is a completely assembled engine, ready to drop into your vehicle or project. Unlike sourcing used parts and rebuilding an engine, a crate motor offers the convenience of a brand-new, factory-tested powerplant. These engines typically include all major components like the block, cylinder head, crankshaft, pistons, connecting rods, and fuel system. The exact components included can vary depending on the supplier and the specific crate motor configuration.
Are 12-Valve Cummins Crate Motors Still Available?
While Cummins doesn't directly offer new 12-valve crate engines, several reputable suppliers rebuild and sell reconditioned or "crate-style" versions. These are typically built using a combination of new and refurbished parts, meticulously inspected and assembled to exacting standards. Finding a genuinely "new" 12-valve crate motor is uncommon due to the engine's age and the discontinuation of its production.
What are the Advantages of Using a 12-Valve Cummins Crate Motor?
Using a 12-valve Cummins crate motor offers several significant advantages:
- Reliability: The 12-valve's renowned durability is a primary draw. A crate motor leverages this inherent strength with the added benefit of a thorough rebuild, minimizing the risk of unforeseen mechanical failures.
- Convenience: Instead of sourcing individual parts and spending time and effort on a complex rebuild, a crate motor provides a streamlined installation process, significantly saving time and labor costs.
- Performance: A properly built crate motor offers consistent performance, eliminating the variability associated with used engines that may have unknown wear or modifications.
- Warranty: Many reputable suppliers offer warranties on their crate motors, offering peace of mind.
Where Can I Buy a 12-Valve Cummins Crate Motor?
Several companies specialize in supplying rebuilt and reconditioned 12-valve Cummins engines. It's crucial to research thoroughly and choose a reputable supplier with a proven track record and positive customer reviews. Always inquire about warranties, specifications, and the source of the components used in the crate motor.
How Much Does a 12-Valve Cummins Crate Motor Cost?
The price of a 12-valve Cummins crate motor varies widely depending on the engine's condition, modifications (if any), and the supplier. Expect to invest a considerable sum compared to purchasing a used engine, but the convenience, reliability, and potential warranty often justify the higher cost.
What are the Different Variations of 12-Valve Cummins Crate Motors?
While all are based on the same fundamental design, variations exist. These may include differences in displacement (e.g., 5.9L, 6.7L), horsepower and torque ratings, and specific components included. Some suppliers may offer custom configurations to meet specific customer requirements. Clarify the exact specifications before purchasing.
What is the typical horsepower and torque output of a 12-Valve Cummins crate motor?
The horsepower and torque figures for a 12-valve crate motor can vary depending on the specific engine's modifications and condition. Stock 12-valve engines typically range from approximately 160 to 230 horsepower and significantly more torque. However, heavily modified crate motors can exceed these figures. Always confirm the output specifications with the supplier.
This comprehensive guide helps potential buyers navigate the world of 12-valve Cummins crate motors. Remember that thorough research and selecting a reputable supplier are crucial for a successful project. The legendary reliability and power of this engine, packaged in a convenient crate motor format, make it a tempting option for many projects.
