Brian Crower is known for making high quality camshafts that make power without breaking the bank. There is no other cam manufacturer on the market that gives you more value for your dollar, and the parts just work. We use them in our own cars and we encourage our customers to use them as well.
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.
