Acura Integra GS-R Sedan

From Acura press: The GS-R Sports Coupe and Sports Sedan feature an all-new, 1.8 liter, DOHC, 4-cylinder, 170-horsepower, VTEC-equipped engine, mated to an upgraded S-speed manual transmission. GS-R models also feature wider, larger-diameter 6.0 JJ x 15-inch alloy wheels and 195/55 R15 V-rated tires.

The GS-R model features an all-new engine that shares virtually no components with the 1993 Integra GS-R engine. The 1797 cc engine is equipped with the Variable Valve Timing and Lift Electronic Control (VTEC) system pioneered in the Acura NSX. It also features Programmed Fuel Injection (PGM-FI), a dual-stage intake system, a knock sensor, a crankshaft reinforcing bridge, oil jet piston cooling and a number of other innovations to improve reliability and durability, and to provide smoother operation. All this adds up to 170 horsepower at 7600 rpm and 128 lbs-ft of torque at 6200 rpm. These impressive figures give it one of the highest specific output of any normally aspirated engine sold in the U.S., and its relatively long stroke and high redline give it the highest piston speed of any automobile engine in the world, even faster than the latest Formula One engines.
