The Honda K series have cast iron sleeves as opposed to the FRM cylinders found only in a roadster that is named for its what?
Honda K engine The Honda K series engine is a four-cylinder four-stroke engine introduced in 2001. The 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-series & F-series engines, as opposed to the FRM cylinders found in the H-series and newer F series engines found only in the Honda S2000.
Toyota FZ engine The Toyota FZ engine was a 24-valve, 4.5L DOHC straight-6 internal combustion engine manufactured by Toyota to replace the F-series engine. It was used primarily in SUVs because of its large displacement, smoothness, ruggedness and torque.
