From Acura press: The third-generation Acura Integra (introduced in 1994) features a number of technological innovations that enhance performance and handling and provide high levels of safety, durability, efficiency, comfort and ride quality. The Integra is available as a Sports Coupe or Sports Sedan. For 1999 the Sports Coupe and Sports Sedan come in three trim levels- LS, GS and GS-R.
The Integra has evolved and matured in its three generations. The Integra offers a comprehensive list of standard luxury, comfort and safety features. It features a standard driver's and front passenger's air bag Supplemental Restraint System (SRS) in all models. Additionally, features such as an AM/FM cassette/CD six-speaker music system, a power moon roof, windows, door mirrors and locks, Antilock Braking System (ABS) and a lumbar/height/tilt adjustment for the driver's seat are all standard equipment.
For 1999 Integra models receive updated styling and various feature enhancements. The Integra features two distinct engines. The LS and GS models offer an all-aluminum, 1.8-liter, 16-valve, DOHC, 4-cylinder engine with programmed fuel injection (PGM-FI). This power plant produces 140 horsepower at 6300rpm and 127lb ft of torque at 5200 rpm.
The GS-R features a 1.8-liter engine equipped with the Variable Valve Timing 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 bridge, oil jet piston cooling and a number of other innovations to durability and smoother operation. All this adds up to 170 horsepower and 128 lb ft of torque at 6200 rpm. These impressive figures give it one of the highest specific outputs of any normally aspirated engine sold.
The VTEC system, first pioneered in the Acura NSX, works similar performance magic in the Integra GS-R. As the performance of the NSX has already been amply demonstrated, VTEC is an innovative solution to an age-old automotive engineering problem. It elegantly solves the trade-off between tuning an engine for either high-end horsepower or low-end torque. With VTEC, engineers no longer have to compromise between the two. VTEC-equipped engines can have the best of both, especially when the system works in conjunction with the dual-stage intake manifold.
