K20A / K20Z

The newest engine in the Honda tuning community. The "K Series" is Honda's mass produced version of the roller rocker valve train assembly found in the S2000. Less friction, more rpm potential, faster action cam profiles...this engine has untapped potential. First introduced in the JDM Integra Type-R in 2001, this engine put out a respectable 220HP @ 8000 rpm straight from the factory (DC5). The K20A also sees service in the JDM Civic Type-R, using the same compression and cam profiles. The first USDM production model was the K20A2 found in the 02-04 RSX-S. Other engines featuring the same head configuration include the K24A2 (TSX) that features a 9.114" deck height, the K20Z1 in the 05-06 RSX-S that includes various JDM Type-R add-ons like cams, throttle bodies, higher compression and Honda's answer to the tuning crowd, the K20Z3 found in the 2006-up Civic Si.

BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm applications. The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finis...
