This is a tuned 2150cc engine, model K20A. It uses a Toda Racing 2.15 kit. M&M HONDA assembles the engine with high precision, based on the technology it has cultivated over many years and its unique philosophy of extracting the best engine performance. The engine's feel is significantly improved, and the crisp throttle response unique to naturally aspirated engines is restored! During the work process, dummy heads are used for boring and honing, ensuring precise clearances and allowing for more precise assembly. Furthermore, the engine assembly room is thoroughly temperature-controlled, contributing to the precise assembly of each component.
It is introduced in Ameblo's "M&M HONDA's Honda Honki".
