GMC Typhoon

The GMC Typhoon was a high-performance version of the GMC Jimmy SUV. Produced in 1992 and 1993, the Typhoon was based on the 1991 GMC Jimmy SUV.

Both the GMC Syclone and Typhoon (SyTy) trucks featured a Mitsubishi TD06-17C/8cm2 turbocharger and Garrett Water/Air intercooler attached to a 4.3L 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 5.7L GM Small-Block engine. All SyTy's had a GM 700R4 transmission (4L60) 4-speed automatic transmission and a BorgWarner 1372(Syclone)/4472(Typhoon) 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 280hp (209kW) and 360ft·lbf (488N·m), but some stock Typhoons have been measured at over 300hp (224kW) on a dynamometer.
