1992 Acura Integra GS-R Test Drive

New credibility comes by way of the Integra GS-R, an enthusiast’s Integra fitted with the highest specific output, normally aspirated reciprocating engine found in a U.S.-version passenger car today— a peak of 160 bhp from a piddling 1678 cc, or 95 bhp/liter. Honda has taken the Japanese-market 16-valve dohc 1.6-liter inline-4, lengthened its stroke by 4 mm and given it such bits as a forged steel crankshaft, light weight oil-jet-cooled pistons, and a 14-percent-lighter fly wheel that help it rev smoothly to 8000 rpm. All developed under the ever-competitive eye of engineers who engineered the 1.5-liter turbocharged V-6 engines that won 15 of 16 Formula 1 races in 1988.
