Both the Syclone and Typhoon ("SyTy") trucks featured a Mitsubishi TD06-17C/8cm² turbocharger and Garrett Water/Air intercooler attached to a 4.3 L "LB4" V6 engine with forged pistons, main caps, head gaskets, intake manifolds, fuel system, exhaust manifolds, and a 48mm twin-bore throttle body from the 5.7 L GM Small-Block engine. All SyTy's had a GM 700R4 transmission (4L60) 4-speed automatic transmission and a BorgWarner 1372/4472 transfer case splitting torque with 35% forward and 65% to the rear wheels. Both trucks featured all-wheel drive, upgraded brakes, and sport modifications to the standard suspensions. Unlike the Syclone, the Typhoon featured an air-operated self-leveling rear suspension. Output was officially 280 hp (209 kW) and 360 ft·lbf (488 N·m), but some stock Typhoons have been measured at over 300 hp (224 kW) on a dynamometer.

The Typhoon was capable of accelerating from 0-60 mph in 5.3 seconds and could do a quarter-mile run in 14.1 seconds at 95 mph (153 km/h). "Car and Driver" was impressed, comparing the Syclone's performance favorably to the Ferrari 348ts, Chevrolet Corvette, and Nissan 300ZX Turbo. It was a bargain at US$29,970, though the magazine criticized the plasticky interior pieces.

All three trucks were built for GMC by Production Automotive Services of Troy, Michigan. Aside from a handful of prototypes, only 4,697 Typhoons were built by GMC: 2,497 in 1992, and 2,200 in 1993.
