Approx. performance specs for K-series engines

At the center of the K Series universe lies the K20 engine. This 2.0-liter marvel is available in several variants, each tailored to deliver specific performance traits. The K20A2, often hailed as one of the finest naturally aspirated engines ever made, boasts an impressive 200 horsepower and 142 lb-ft of torque. The K20Z3, on the other hand, emphasizes torque delivery with 197 horsepower and 139 lb-ft of torque. Both engines feature variable valve timing and a high-revving nature that Honda engines are renowned for.

The K20 engine’s internals are equally impressive. Forged pistons, lightweight connecting rods, and a robust crankshaft contribute to its durability and performance potential. A dual overhead cam (DOHC) setup with four valves per cylinder ensures efficient breathing, while Honda’s i-VTEC system optimizes valve timing for both low-end torque and high-end power.
