A Kubota Diesel Swap offers a significant upgrade for classic vehicles like the Willys Jeep. This article details the process of replacing the original engine in a 1949 CJ2A with a Kubota V2203 turbo diesel engine, focusing on the benefits and modifications required for this conversion.
Why Choose a Kubota Diesel Swap?
The Kubota V2203 is a popular choice for Willys Jeep owners seeking increased torque and fuel efficiency. Diesel engines are known for their durability and low-end power, making them ideal for off-roading and challenging terrain. While some purists may object to modifying a classic vehicle, this upgrade prioritizes reliability and performance enhancements for a more capable and enjoyable driving experience. This particular project builds upon previous upgrades, including improved brakes, a 12-volt electrical system, an overdrive unit, seat belts, and an auxiliary fuel tank.
Preparing the Kubota V2203 Engine
The original L-head engine, while still functional, will be replaced with a used Kubota V2203. The engine was acquired and underwent a thorough cleaning and painting process in preparation for installation. A conversion kit, turbo kit, and a later model bell housing were sourced from Overland Diesel to facilitate the swap. The original engine will be available for sale upon removal.
Modifications and Considerations for the Swap
The Kubota diesel swap requires several modifications to ensure proper fit and functionality. The conversion kit from Overland Diesel addresses many of these challenges, providing necessary adapters and components. The project also involves:
- Gauges: The plan is to retain the stock Jeep gauges and incorporate a separate two-gauge panel under the dash. This panel will house a boost gauge and a pyrometer to monitor the turbocharged diesel engine’s performance.
- Heaters: The CJ2A’s dual heaters will be retained to maintain comfortable cabin temperatures.
Next Steps and Future Plans
The next stage of the project involves removing the original L-head engine. Following the engine removal, the Kubota V2203 will be installed using the conversion kit. The project aims to create a more powerful and reliable CJ2A, capable of handling various driving conditions while preserving some of its original charm. This Kubota diesel swap demonstrates how classic vehicles can be modernized for improved performance without sacrificing their unique character.
