The 2017 Civic kind R is features the most an effective engine ever available in a Honda production automobile in America. The type R"s 2.0-liter 16-valve i-VTEC® DOHC direct-injected, turbocharged powerplant developments performance on lot of fronts through a optimal output the 306 horsepower at 6500 rpm and also 295 lb.-ft. The torque in between 2,500 and also 4,500 rpm. The Civic kind R is the pure pinnacle of civic performance, and ranks together the fastest Honda production auto ever available in America, through a track top speed of roughly 170 mph.
The 2.0-liter turbocharged engine is make by Honda the America Mfg. In ~ its Anna, Ohio engine plant using domestic and also globally sourced parts. Completed engines room shipped come Honda of the U.K. Manufacturing in Swindon, England, where the kind R is manufactured. Particularly engineered for straight injection and turbocharging, v an ultra-lightweight forged steel crankshaft and also forged steel connecting rods, the type R powerplant is draft to offer maximum torque output in the mid-rpm variety to provide instantly accessible power.
Offered solely with a 6-speed manual transmission, the high-strength gearbox provides a short-throw transition action and also closely spaced ratios tailored to fit the 2.0-liter turbo"s power delivery. A driver-selectable rev-matching attribute smooths high power upshifts and also downshifts, and also to help put the power to the ground, a helical limited-slip prior differential is standard.

Engine Architecture and Features
Turbocharged i-VTEC 2.0-Liter In-Line 4 Cylinder Assembled in Honda"s Anna, Ohio engine plant, the Civic form R"s DOHC 2.0-liter engine is the most an effective engine ever readily available in a manufacturing Honda in America. With 33-percent better displacement 보다 the various other turbocharged engines offered in the public family, the type R powerplant is engineered to deliver boost of 101 horsepower and 103 lb.-ft. Of talk when compared to the next most powerful Civic, the civic Si Coupe and also Civic Si Sedan. With straight injection, low-inertia high-flow mono scroll turbo mechanism with electrical waste-gate and a best of 23.2 psi that turbocharger boost, the form R powerplant establishes the horsepower and torque that a far larger, typically aspirated engine.

Cylinder Block and Crankshaft The Civic type R’s 2.0-liter inline 4-cylinder engine has actually a lightweight die-cast aluminum block through reinforced key bearing hat to minimization weight. Centrifugally actors iron cylinder sleeves administer long-lasting durability. In the attention of engine responsiveness, a specially developed, at sight lightweight forged-steel crankshaft is used specifically in the Civic kind R. Each newspaper on the crankshaft is micropolished to alleviate operating friction.
Pistons and Connecting Rods The 2.0-liter engine’s pistons have “cavity-shaped” crowns that help maintain secure combustion and also contribute to boosted efficiency. The lightweight pistons have a very closely optimized skirt design to minimize reciprocating weight, which minimizes vibration and increases operation efficiency. The pistons are cooled by oil jets directed at the underside of every piston crown and feature an interior “cooling gallery” prefer Honda Formula 1 engines the is draft to alleviate temperature in the piston ring area. Ion-plated piston rings aid reduce friction for higher operating efficiency. Unique super lightweight, high-strength steel connecting rods are heat-forged in one piece and also then “crack separated” to develop a lighter and stronger rod v an optimally equipment bearing cap.
