These are gaining a following in the import scene, but also among hot rodders and kit car enthusiasts, because they can be put in longitudinal rear wheel drive layouts.Ĥ03lbs (with gearbox), 275lbs (without gearbox)Ģ000–2006 Honda Stream ( JDM) (RN3, FWD) Ģ001–2006 Honda Integra Type S ( JDM) Ģ002–2008 Honda Accord ( JDM) (CL7-CM1, FWD) Ģ002–2008 Honda Accord ( JDM) (CL8, AWD) Ģ002–2004 Honda Integra Type R ( AUDM/ NZDM)

A modified K20C engine is used in motorsport, as the Sports Car Club of America Formula 3 and 4 series that run in North America both use a K20C engine, with the Formula 4 engine not having a turbocharger. In engines such as the K20A2 found in the Acura RSX Type-S, the VTEC system operates on both the intake and exhaust valves, allowing both to benefit from multiple cam profiles. At high engine speeds, both intake valves open fully to improve engine breathing.
The VTEC system on engines like the K20A3 only operate on the intake cam at low rpm only one intake valve is fully opened, the other opening just slightly to create a swirl effect in the combustion chamber for improved fuel atomization.
Two versions of the Honda i-VTEC system can be found on a K-series engine, and both versions can come with variable timing control (VTC) on the intake cam. K20 uses the short block with a deck height of 212 mm (8.3 in) where K23 and K24 block has a deck height of 231.5 mm (9.1 in). Similar to B series, the K-series car engines have two short blocks with the same design the only difference between them being the deck height. The cylinders have cast iron sleeves similar to the B- and F-series engines, as opposed to the FRM cylinders found in the H- and newer F-series engines found only in the Honda S2000. This system forgoes the use of a conventional distributor-based ignition timing system in favor of a computer-controlled system that allows the ECU to control ignition timings based on various sensor inputs.
The engines use a coil-on-plug, distributorless ignition system with a coil for each spark plug. The K-series engines are equipped with DOHC valvetrains and use roller rockers on the cylinder head to reduce friction. The Honda K-series engine is a line of four-cylinder four-stroke car engine introduced in 2001. Components of the i-VTEC system can be seen.
