Not just an economic engine that people modified for performance but one that could flex it’s muscles stock as well as take care of the environment.

There are several other Euro DC5 applications as well as JDM ones that may vary specifics, but Honda didn’t want it’s new DOHC to be a one-trick pony. The later models of the 200’s have included the newer K20Z1 and K20Z3, found in the 2005-06 RSX Type S and Civic Si (FG and FA) which both keep compression around 11.0:1 puts down 210 and 196 respectively. The other more swapped K20 is the K20A3, found in the 2002-06 Base RSX and the Civic Si that has a compression ratio of 9.8:1 and with 160 horsepower. K20A2 is the engine that many USDM EP3 owners swap into their vehicles, and because they are found in the 2002-04 RSX Type S there’s plenty available in the US. There are many upgrades to this engine, from the chromoly flywheel and oil squirters to help cool pistons. The K20A is the engine in the 2001-2006 JDM Inegra DC5 and Civic Type R’s EP3 raised the bar with 220 hp and a compression ratio of 11.5:1. Power and torque varies from each motor, while the K20A3 compression checks in at 9.5:1 – 9.8:1, there are many other versions much more suited for performance. There are several versions of the K20 engine, with the 2.0 liter ranging from the K20A, K20A3, K20A4, K20A6. Need a JDM K20 Swap guide, then check here. It took some time for enthusiasts to start swapping these engines or importing JDM units for their donor cars, but the swap has become very straightforward today. This i-VTEC system has evolved over the past 10 years, but the original K20 engine was equipped with 165hp and was cutting edge for it’s time. Not only does the i-VTEC system combat pumping losses, but because the valves open later the combustion rate is increased due to duration. By controlling the throttle electronically and opening the intake valves faster and later during the combustion cycle, Honda’s system decreases pumping losses. These are priced at £114.42 including VAT 15%.During part throttle operation this valve control system sets the pin in the rocker arms, retarding the closure of intake valves. Secondly, a MUGEN designed wiring loom connector kit built to link the essential sensors to a non standard loom suitable for an aftermarket motorsport ECU. Prices for the throttle bodies start at £339.25 including VAT. Two optional extras are available from MUGEN to enable easy fitment of the K20A engine into motorsport prepared vehicles.įirstly a MUGEN cable operated mechanical throttle body in 60, 62 and 64mm diameters, which is designed to replace the original Honda drive by wire unit. The engines are available now from principal MUGEN parts stockist Torque Developments International Plc, priced at £5462.50 including VAT 15%. These new JDM specification K20A I-VTEC engines are labelled ‘For Motorsport Use Only’ and are supplied minus the drive by wire throttle body and wiring loom on sealed, secured and palletised boxes.
