1986 Isuzu I mark problems
The Isuzu Gemini is a subcompact car produced by the Japanese automaker Isuzu from 1974 until 2000. The same basic product was built and/or sold under several other names, sometimes by other General Motors brands, in various markets around the world. While the first generation was of a rear-wheel drive design, later versions were all front-wheel-drive, and the last two generations were no more than badge-engineered Honda Domani until the name was retired in 2000.
First generation (1974)
The first Gemini was the Bellett Gemini, first seen in November 1974. It was based on the third-generation Opel Kadett C on the General Motors T-car platform and came in four-door sedan and two-door coupe body styles. The chassis code was PF50, although the later 1.8-liter versions were called PF60 and the diesels PFD60.
In June 1977 the Gemini received its first, light, facelift. The bigger 1817 cc G180 series engine became available, fitted with rectangular headlights rather than the round units used on the 1600. This model offered 110 PS (81 kW), although this output dropped to 105 PS (77 kW) if an automatic transmission was fitted. In November of the same year the 1600 was updated, now with square headlights and an engine with the I·CAS oxidation catalyst ("Isuzu Clean Air System") which could manage the 1978 emissions standards. One year later the Gemini 1800's engine was also upgraded to meet the 1978 emissions standards. Power remained unchanged, and the automatic now offered the same power as cars with manual transmission. The ignition system was now of a transistor less type, and the trunk lid was now opened remotely (not added to the Gemini 1600 until the end of December). The Gemini Black and 1800 Minx were also added, the Minx with a two-tone paintjob and the Black with black paintwork and more sporty yet comfortable equipment including alloy wheels.
In June 1979, the Gemini received a new slant nose with rectangular headlights and a redesigned rear end. The changes were actually more comprehensive than that, also including a redesigned (longer) engine bay and a wider radiator opening for two new engines added in November (the twin cam G180W and the new 4FB1 diesel) which both required wider radiators for more air for cooling.
In Japan, sports models were available originally with the "ZZ" name. Later, ZZ/L (1980), ZZ/R (1981), ZZ/T, and ZZ/E models were added. These were equipped with an Isuzu G180W 8-valve DOHC 1.8-liter engine, most commonly fuel-injected, producing 130 PS (96 kW) at 6400 rpm. These models also came with a shortened remote throw manual shift lever and optional factory LSD differential. There was also a mildly sporting model of the OHC 1800, called the LS/G.
In October 1982 a version of the diesel with Bosch VE electronic fuel injection was also added; this provided 8% more power than the regular version (66 versus 61 PS) and was fitted to the LT-E and LJ-E models. For those who wanted more, a 73 PS (54 kW) turbo diesel appeared a month later. Also featuring electronic fuel injection, this model also received a standard rear anti-roll bar. Counterintuitively, the two more powerful diesels were never available with the coupé bodywork.
The Gemini was complemented in 1981 by the Giugiaro-designed coupé Isuzu Piazza, based on the Gemini's platform, which was introduced in the United States in 1983 as the Isuzu Impulse and in Australia in 1986 as the Holden Piazza. After the front-wheel-drive second generation Gemini appeared in early 1985, the old rear-wheel drive version nonetheless continued to be built. The coupé model was discontinued, and a slimmed down sedan range (including the ZZ and diesel models) continued to be available. This diminished range was produced until February 1987, when the rear-wheel drive Gemini was laid to rest after 768,537 had been built.
