what motor is in a 2007 honda civic si
Honda Civic Si The Si was redesigned for the 2006 model year along with all other Civic trims, bringing about significant changes from the previous generation. The car comes with a 2.0-liter K20Z3 i-VTEC engine that produces 197 hp (147 kW; 200 PS) and 139 lbf·ft (188 N·m) of torque, while also including a 6-speed manual transmission with a helical limited slip differential. Forty percent stiffer spring and dampening rates from the non-Si trims and stiffer sway bars have bolstered the Civic Si's handling,[3] with the car achieving 0.90g (8.8 m/s2) of lateral acceleration on the skidpad. It is also the quickest Civic Si off the line, with a factory 0–60 time of 6.7 seconds according to Honda.[4] Some new features include a moonroof, a seven-speaker 360-watt sound system, 17-inch alloy wheels with 215/45R17 Michelin all-season tires, and key-less trunk access.
