CAMSHAFTS - STAGE 2 Boost/NA Street (Honda/Acura K20A3/K24A1) A USDM only production engine, the K20A3 and similar cylinder head configurations were developed for a performance, yet economical mindset. Although VTEC, it is only featured on the intake camshaft. The K20A3 is found in the 01-03 Civic Si while the K24A1 is in the 01-03 CR-V. The K24A4 is the most popular of them all due to the fact that was used to service the 03-up Accord as well as the 02-03 Element. Because of it's tall deck height (9.114"), the trend will be to take these blocks and use the K20A/K20Z head found in the 06-up Civic, 01-06 RSX-S for more rpm potential and added tuning ability. However there will be plenty of tuners wanting to stay true and run the original K20A3 head.
Designed for high rpm, BC valve springs are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC retainers and spring seats are CNC machined from 6AL4V titanium to exacting tolerances. Use steel retainer for high mileage applications.
