Honda Integra - First Generation (1986–1989)
DA1 DA3
This vehicle debuted in Japan in 1985 as the Honda Quint Integra before going on sale a year later in North America as part of the then-new Acura lineup. Three and five-door hatchback bodies were available, with a 1.6 L DOHC 16-valve four-cylinder engine powering both. The engine was the vehicle's most publicized feature, as DOHC, multi-valve engines were anything but commonplace in entry-level models at the time. The 5-door hatchback model was also sold in Australia but was rebadged as the Rover 416i. The first generation Integras actually came
with two different engines. Although they shared the same engine code (D16A1), there were a few differences. The engine differed in the years 1986 to 1987 and 1988 to 1989. The two engines are commonly called the "Browntop" and "Blacktop" due to the color of their valve covers. The "browntop" came in 1986 and 1987 Integras while the "blacktop" came in 1988 and 1989 models. The improvements in the "blacktop" engine included lighter rods, domed pistons for slightly higher compression, and an electric advance distributor (the "browntop" came with a vacuum advance distributor). The overall gain in performance was about 5 hp (3.7 kW) for 118 hp (88.0 kW).
