models, including five-lug wheel bolts. Alpina models The Alpina C1, C2, B3 and B6 models were based on the E30. Special models 320is For Portugal and Italy only, due to considerably higher taxes for cars with engines exceeding 2000 cc, a special model was created: the 320is. The four-door version appeared in the dealers' showrooms in September 1987 while the two-door followed in March 1988. Production of the 320is continued until 1991. This model was equipped with a version of the S14 engine from the M3, with stroke reduced to . This engine produced at 6900 rpm and at 4,900 rpm. The 320is shared the same dogleg Getrag 265 gearbox of the non-US M3 while it had a limited slip differential with the same 25% lock up rate but with a shorter differential ratio of 3.46:1. All the 320is models were left hand drive and without a catalytic converter. Sports suspension was fitted to all two-door models, and to four-doors produced from September 1989. The interior of the 320is was identical to that of other 3 Series models, except an M3 instrument cluster (which features an oil temperature gauge instead of a fuel economy gauge) was used. The 320is was sold for three years, with 1,206 four-doors and 2,542 two-doors produced. M325i In New Zealand, where the M3 was never sold by BMW, the local importer created a sporting version of the sedan called M325i. About 100 such cars were imported beginning in late 1986 until at least 1990. Fitted with the standard non-catalyzed 2.5 litre engine they benefited from a Motorsport tuned suspension, the M-Technic body package, 15-inch BBS cross-spoke wheels with wide, low profile (225/50) tyres, and a limited-slip differential. The M325i is quite similar to the British market 325i Sport, also developed as a response to the absence of a right-hand-drive M3. 333i BMW South Africa's Motorsport division created the 333i in 1985 by fitting the 3.2 L M30 "big six" engine to a two-door E30. The resulting 333i was a success in South African saloon car racing. These cars were built with help from Alpina in Buchloe, Germany. Due to the space constraints caused by the large M30 engine, the buyer was forced to choose between air conditioning (highly desirable in South Africa) and power steering. Cars with power steering are distinguished by having foglights, cars with air-conditioning instead had ducts providing fresh air for the
