Question:  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?

Context paragraphs:
Cast iron: Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%.  Its usefulness derives from its relatively low melting temperature.  The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing.

John Wilkinson (industrialist): John "Iron-Mad" Wilkinson (1728 – 14 July 1808) was an English industrialist who pioneered the manufacture of cast iron and the use of cast-iron goods during the Industrial Revolution.  He was the inventor of a precision boring machine that could bore cast iron cylinders, such as those used in steam engines of James Watt.  His boring machine has been called the first machine tool.  He also developed a blowing device for blast furnaces that allowed higher temperatures, increasing their efficiency.

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.

Plasma transferred wire arc thermal spraying: Plasma transferred wire arc (PTWA) thermal spraying is a thermal spraying process that deposits a coating on the internal surface of a cylindrical surface, or external surface of any geometry.  It is predominantly known for its use in coating the cylinder bores of an engine, enabling the use of aluminum engine blocks without the need for heavy cast iron sleeves.  A single conductive wire is used as "feedstock" for the system.  A supersonic plasma jet melts the wire, atomizes it and propels it onto the substrate.  The plasma jet is formed by a transferred arc between a non-consumable cathode and the wire.  After atomization, forced gas transports the stream of molten droplets onto the bore wall.  The particles flatten when they impinge on the surface of the substrate, due to their high kinetic energy.  The particles rapidly solidify upon contact and can form both crystalline and amorphus phases.  There is also the possibility to produce multi-layer coatings.  The stacked particles make up a highly wear-resistant coating.  All conductive wires up to and including 0.0625" (1.6mm) can be used as feedstock material, including "cored" wires.  PTWA can be used to apply a coating to the wear surface of engine or transmission components to replace a bushing or bearing.  For example, using PTWA to coat the bearing surface of a connecting rod offers a number of benefits including reductions in weight, cost, friction potential, and stress in the connecting rod.

Honda S2000: The Honda S2000 was a roadster that was manufactured by Japanese automaker Honda from 1999 to 2009.  First shown as a concept car at the Tokyo Motor Show in 1995, the production version was launched in April 1999 to celebrate the company's 50th anniversary.  The S2000 is named for its engine displacement of two liters, carrying on in the tradition of the S500, S600, and S800 roadsters of the 1960s.

Chevrolet 2300 engine: The 2300 is a 2287 cc inline-four engine produced by the Chevrolet division of General Motors for the 1971 to 1977 model years of the Chevrolet Vega and Chevrolet Monza.  It featured a die-cast aluminum-alloy cylinder block.  The high-tech block features an alloy with 17 percent silicon.  During the machining process, the cylinders were etched leaving the pure silicon particles exposed providing the piston wear surface, eliminating the need for iron cylinder liners.  The block has cast iron main caps and a cast iron crankshaft.  The engine's cylinder head is cast iron for lower cost, structural integrity and longer camshaft bearing life.  The valvetrain features a direct-acting single overhead camshaft design.

Gray iron: Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure.  It is named after the gray color of the fracture it forms, which is due to the presence of graphite.  It is the most common cast iron and the most widely used cast material based on weight.

Ductile iron: Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis.  While most varieties of cast iron are brittle, ductile iron has much more impact and fatigue resistance, due to its "nodular graphite" inclusions.

Cast iron pipe: Cast iron pipe is a pipe which has had historic use as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 19th and 20th centuries.  It comprises predominantly a gray cast iron tube and was frequently used uncoated, although later coatings and linings reduced corrosion and improve hydraulics.  Cast iron pipe was superseded by ductile iron pipe, which is a direct development, with most existing manufacturing plants transitioning to the new material during the 1970s and 1980s.  Little cast iron pipe is currently manufactured.

John Cragg: John Cragg (1767 – 17 July 1854) was an English ironmaster who ran a foundry in Liverpool, Merseyside, England.  He was born in Warrington (then in the historic county of Lancashire, now in the ceremonial county of Cheshire).  His business was the Merseyside Iron Foundry, which was located in Tithebarn Street, Liverpool.  Cragg was an enthusiast in the use of prefabricated ironwork in the structure of buildings, and in the early 19th century became interested in building churches.  He had been discussing building a church in Toxteth Park, Liverpool, and in 1809 plans had been drawn up for this by J. M. Gandy.  This church was never built, but in 1812 Cragg met Thomas Rickman, and together they designed the three churches in Liverpool incorporating Cragg's cast iron elements.  The first of these was St George's Church, Everton (1813–14).  The exterior of this church is largely in stone, but the framework of its interior, including the galleries, and the window tracery are in cast iron.  The ceilings consist of slate slabs supported by cast iron rafters, which are decorated with cast iron tracery.  The second church resulting from this collaboration was St Michael's Church, Aigburth (1813–15), Here, in addition to the cast iron framework of the interior, and the window tracery, the parapets, battlements, pinnacles, hoodmoulds, the dado, and other details are also in cast iron.  The area around the church, known as St Michael's Hamlet contains five villas containing many cast iron features.  The third cast iron church was St Philip's Church (1815–16) in Hardman Street, Liverpool, which was closed in 1882 and demolished.  Some cast iron fragments have been incorporated in the fabric of the block of buildings now occupying the site of the churchyard.  Cragg did not marry.  He died on 17 July 1854, aged 87, and was buried in St James Cemetery, Liverpool.
