In 1984 Ford’s Special Vehicle Operations, only a few years old, created the Mustang SVO. It featured a unique front fascia with a revised headlight layout, a dual-wing rear spoiler and a functional, off-center hood scoop. That scoop fed a turbocharged 2.3-liter four with an output of 175 horsepower—the same as the high-output version of that year’s venerable 5.0 V-8.

More than just a new engine and new look, the Mustang SVO also received some chassis upgrades, including larger sway bars, Koni gas shocks, four-wheel disc brakes, and 16-inch wheels wrapped in Goodyear Gatorback radial tires. The cabin of the Mustang SVO featured Recaro bucket seats, leather-wrapped steering wheel, Hurst shifter and additional gauges for water temp, oil pressure, and turbo boost.

The base engine in the Fox body Ford Mustang continued to be the 2.3-liter inline-4, making 88hp. A mid-range 3.8-liter V-6 made 120hp. A Turbo GT featured the forced-induction 2.3-liter, making 145hp. Two 5.0 V-8 engines were offered. The standard output was 160hp, while the high-output version made 175hp.

To commemorate 20 years of the Ford Mustang, a 20th Anniversary Edition was created. Offered with either the 5.0 or Turbo, it was painted Oxford White with a Canyon Red interior. Along the side ran a “GT350” decal, and was available in fastback or convertible variants.

1984 also marked the first year of the Saleen Mustang. It featured aggressive aerodynamic ground effects and heavily revised suspension, but would not see any serious engine modifications. If you’re looking for a Saleen Mustang, later models had more seriously tweaked performance.
