Can the Mazda3 1.5 be upgraded to 2.0?
1 Answers
The Mazda3 1.5 manual transmission can be upgraded to a 2.0 engine. The transmission does not need to be replaced, as the transmissions for both models are interchangeable and identical. Introduction to Displacement: Displacement, a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. The space volume through which the piston moves from top dead center to bottom dead center is called the cylinder displacement; if the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Importance of Engine Displacement: Engine displacement is one of the most important structural parameters, representing the size of the engine more accurately than bore diameter and the number of cylinders. Many performance indicators of the engine are closely related to displacement. Generally, a larger displacement means the engine releases more energy per unit time (converting the chemical energy of fuel into mechanical energy), resulting in better "power performance." It's like comparing a teenage boy to a healthy adult—the adult is naturally more efficient at physical labor. Therefore, off-road vehicles and sports cars typically have relatively larger displacements.
