A collection of components designed to overhaul and restore a specific type of air-cooled engine to its original or improved condition. The numerical designation within the phrase refers to the engine’s displacement, expressed in cubic centimeters, after the rebuild is complete. This implies an increase in engine size from its factory configuration. Such kits generally include pistons, cylinders, piston rings, gaskets, bearings, and other necessary hardware required for the reconstruction process.
The practice of increasing the displacement of this particular engine type is commonplace in the automotive modification community, offering enhanced performance capabilities. The larger displacement typically results in a noticeable improvement in torque and horsepower, beneficial for increased acceleration and overall driving experience. Furthermore, its popularity stems from a rich history of aftermarket support and readily available resources for enthusiasts and professional mechanics alike. The components within such collections are often selected to provide a balanced and reliable upgrade, ensuring longevity and efficient operation.
