These price ranges are just estimates, and the actual cost of an engine may vary depending on a number of factors, such as the condition of the engine, the demand for that particular engine, and the location where you are buying it.
It is important to note that rotary engines, like the ones found in the Mazda RX-7, can be more complex and expensive to maintain compared to piston engines. If you are considering purchasing an RX-7, it is important to factor in the cost of potential maintenance and repairs when budgeting for the car.
