![]() Magic Engine 1.1.3 Series Of TheThe K-series engines are equipped with DOHC valvetrains and use roller rockers to reduce friction. The engines use a coil-on-plug, distributorless ignition system with a coil for each spark plug. 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 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. ![]() 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. At high rpm, both intake valves open fully to improve engine breathing. 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. 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. Combustion Fuel system Fuel injection Management ECU Fuel type Petrol Cooling system Water-cooled Piston Oil Squirters (K24A) Output Power output See left for specific application. Dimensions Dry weight 403lbs (with gearbox), 275lbs (without gearbox). Then the JDM K20A type-R engine block would be returned to the production assembly line to complete the engine building process. Combustion Turbocharger 1 (Except K20C2) Fuel system Direct fuel injection Management ECU Fuel type Gasoline Cooling system Water-cooled Output Power output See left for specific application. This modified version produces 272 hp and 280 lb-ft of torque. Thus, reducing the 2006 Acura RSX Type S rating from 210 hp (160 kW) to 201 hp (150 kW) on paper. The K20Z3 has Hondas traditional performance VTEC (as found on previous generation of engines) on the intake and the exhaust cams. Variable cam timing technology is included on the intake but not the exhaust cams. The added timing control corresponds to the added i in i-VTEC. Maximum boost pressure is 13.5psi. The engine includes i-VTEC and VTC technologies and comes mated to a version of Hondas 5-speed automatic with SH-AWD (note: SH-AWD was standard from 2007-2009 and optional from 2010-2012). ![]()
