These smaller accessory pulleys necessitated a shorter serpentine belt. The water pump pulley also decreased in diameter by the same amount in order to preserve the ratio of pump speed, and thus coolant flow.

Accessories - The crankshaft pulley diameter decreased by 14% (as compared to the GT) in order to under-drive the alternator, A/C, and smog pump, all to increase power.

A specially calibrated X3Z EEC-IV engine control unit runs the system.

Air/Fuel Delivery - The increased airflow and fuel consumption of the Cobra required these upgraded components: Larger (compared to the GT) 24 lb/hr fuel injectors, 2.75" (70.0 mm) MAF meter, 2.56" (65.0 mm) throttle body, and matching EGR plate handle the increased breathing of the motor.

Camshaft - The cam is of the hydraulic roller type (same as the GT).

Part Numbers: F3ZZ-9424-C (upper manifold) and F3ZZ-9424-D (lower).

The lower manifold was identical to the GT-40 manifold used by Ford Racing it redirects airflow to a rectangular port configuration as needed by the cylinder heads.

Intake Manifold - The Cobra upper manifold was unique to the 1993 Cobra and had a 2.75" (70.0mm) diameter round throttle body opening, diverting air into (8) round staggered ports, each 1.64" (41.7 mm) diameter.

The valves are actuated by Cobra-specific 1.7 ratio roller rockers, constructed of aluminum and produced for Ford by Crane Cams. They were milled for 62.5 cc combustion chambers.

Cylinder Heads - GT-40 "High Flow" Cast Iron heads were installed.

To this, Ford SVT engineers added the following performance items: The 1993 SVT Cobra's short block (cylinder block, crankshaft, rods, and pistons) was carried over from the GT model. The engineering number is usually what is stamped/cast on the part itself (the fourth character is E for engine parts, F for electronics, and C for chassis).

In many cases, Ford has two separate numbers for each part, the Ford production number (the fourth character is a Z), and an engineering number. This was accomplished with model-specific springs and sway bars.įord part numbers are listed below. Cobra models received a softer, more compliant ride compared to the GT model. The drivetrain received an upgraded transmission, rear disc brakes, and for the first time on a factory Mustang, 17-inch unidirectional wheels. Acceleration from zero to 60 mph (97 km/h) took 5.9 seconds. According to Road & Track, this could send a Cobra through the 1/4 mile in 14.5 seconds at a trap speed of 98 mph (158 km/h). The upgrades were beneath the bodywork and featuring a 302 cu in (4.9 L) V8 engine, producing 235 bhp (238 PS 175 kW) at 4,600 rpm and 280 lb⋅ft (380 N⋅m) of torque at 4,000 rpm. The exterior of the 1993 SVT Cobra was similar to that year's GT model with differences explained below. It was the premier vehicle of Ford's newly established SVT division, designed to showcase SVT's four hallmarks of performance, substance, exclusivity, and value. The 1993 Ford Mustang SVT Cobra was launched during the 1992 Chicago Auto Show.
