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.
