Mazda MX-5 1990 Workshop Manual

Mazda MX-5 / Miata – Roadster, which appeared in 1989, produced by Mazda. The development was carried out in conjunction with the engineers of Lotus Cars, as a result the car inherited the main features of classic British sports cars (light weight, engine inside the wheelbase, rear-wheel drive, simplicity of design).

1st generation

The first generation was shown on February 10, 1989 at the Chicago Auto Show, with a price tag of US $ 14,000. Production start: May 1989 (USA, Canada); September 1, 1989 (Japan); 1990 (Europe).

The body of the NA was all-metal steel, aluminum hood. He weighed 980 kg. The drag coefficient was specified as 0.38. The suspension was independent, with levers on all four wheels, with a stabilizer bar in front and rear.

MX-5 was delivered with a 1.6 liter engine, 116 hp, the power supply system – distributed injection. This engine, codenamed B6ZE (RS), was specifically designed for the MX-5. He had a lightweight crankshaft, flywheel and aluminum crankcase with cooling fins. Production of the first generation ended in 1997.

2nd generation

The second generation was shown in October 1997, in 1998 went on sale.

The NB continued to use an independent suspension for all four wheels, with larger diameter lateral stabilizers in front and behind, but the wheels, tires and brakes were significantly upgraded: an anti-lock braking system was offered as an option; alloy wheels are currently 14 inches (360 mm) or 15 (380 mm) in diameter and 6 inches (150 mm) in width, depending on the package finish; sports models were equipped with wheels and larger tires – 195 / 50VR15. Sales of the second generation ceased in 2005.

3rd generation

The MX-5 NC was delivered in the USA with a 16-valve 2.0-liter engine, 170 hp, combined with either a 5-speed or 6-speed manual transmission. Australia offered the 2.0 MZR L (120 cu), with a power of 118 kW (158 hp) and 188 Nm (139 lb-ft) and a 6-speed gearbox, where the limited slip differential was standard. In Europe, two engines were offered: 2.0 L (120 cu) the MZR with a capacity of 158 hp (118 kW) and 188 Nm (139 lb · ft), in combination with a 6-speed manual transmission; and a new 1.8 L (110 cu in) MZR, with a capacity of 126 hp (94 kW) and 167 Nm (123 lb · ft), combined with a 5-speed manual transmission.

In 2008, the MX-5 was restyled. Changes were: grille, speaker, fog lights, side sills (moldings), rear bumper and rear lights. Sales of the MX-5 NC ended in 2015.
