Acura Integra Type R
From Acura press: The limited-edition Integra Type R Sports Coupe has been developed to maximize the sporty car's dynamic capabilities and further emphasize Acura's belief that driving is its own reward. There were three primary targets during the development process: performance, handling and control, and an exciting driving experience. Engineering teams, which included racing veterans from the Formula One ranks, incorporated the dynamic essence of true race cars while developing the Type R, and thoroughly carried the "driving pleasure" theme through every stage of development. Not surprisingly, a heavy emphasis was placed on the Type R's performance on the racetrack during development, all in an effort to deliver an exciting car with exceptional acceleration, braking and handling capabilities.
The limited production Type R model first joined the Acura Integra line-up in 1997 and was an overnight sensation. Like its fellow Integra models, the Type R features numerous technological innovations that maximize performance and handling, and provide high levels of safety, durability and efficiency. However, it goes a step further by embodying the spirit and technological achievements demonstrated in Formula One racing. Thus, it is clear that engineers placed a heavy emphasis on the performance characteristics of the Type R during development.
The Integra Type R features an advanced 1.8-liter, 195-horsepower, dual overhead cam, 16-valve inline 4-cylinder engine equipped with the Variable Valve Timing and Lift Electronic Control (VTEC) system pioneered in the Acura NSX.
The engine also features Programmed Fuel Injection (PGM-FI), a highly rigid crankshaft with eight full balance weights, a crankshaft reinforcing bridge, an oil cooling system and oil jet piston cooling, dual-spring intake and exhaust valves, a highly rigid integrated aluminum die-cast engine stiffener, and a number of other technologies to increase performance while maintaining reliability and durability, along with smooth operation.
To get the most out of the engine's added horsepower, the Type R also features a close-ratio, 5-speed manual transmission and a limited slip differential. The development emphasis was placed on dramatically increasing performance at high rpm. This emphasis resulted in an engine with a significantly different character than the Integra GS-R, further reinforcing the Type R's image of a limited production, ultra-high-performance sports coupe.
Putting out 195 horsepower at 8000 rpm, and 130 lbs-ft of torque at 7300 rpm, the Type R engine is one of the most powerful normally aspirated mass-produced automobile engines per liter ever produced (108 horsepower per liter).
