Ultimately, the "best" engine for racing will depend on your specific needs and preferences. If you are looking for a high-revving, naturally aspirated engine that is easy to modify and produce more power from, the B18C is a good choice. If you are looking for a larger and more powerful engine with low-end torque and strong midrange power, the B20B is a good choice.
