1991 Gmc Syclone problems
The GMC Syclone is a high-performance version of the GMC Sonoma pickup truck. Produced in 1991 by GMC along with Production Automotive Services (PAS)—the same company credited with building the 1989 Pontiac Turbo Trans Am—the GMC Syclone was the fastest production truck for 1991. Following the Syclone's production, the similarly powered 1992–1993 GMC Typhoon SUV was based on the GMC Jimmy platform. Also following the Syclone, the 1992 GMC Sonoma GT truck was offered as a sport package with the looks of a Syclone but without the price and performance of its turbocharged predecessor. Only 806 Sonoma GTs were produced.
Production run
The GMC Syclone, Typhoon, and Sonoma GT were built by GMC and PAS (Production Automotive Services) of Troy, Michigan, and sold through dealerships. At the time it was introduced, the Syclone was the fastest stock pickup truck being produced in the world. Auto magazines compared its acceleration favorably to a variety of sports cars including the Chevrolet Corvette and—in a memorable comparison test in Car and Driver magazine—a Ferrari 348 ts. The Syclone features a 4.3L turbocharged V6 engine with an automatic transmission and an AWD (all-wheel drive) driveline and 4-wheel anti-lock brakes.
Both the Syclone and Typhoon trucks feature a Mitsubishi TD06-17C 8cm² turbocharger and Garrett water/air intercooler attached to a 4.3L LB4 V6 engine featuring upgrades that included hypereutectic pistons, nodular iron main caps, upgraded head gaskets, intake manifolds, exhaust manifolds, and a 48mm twin-bore throttle body from the 5.7L Chevrolet small-block engine. All Syclones and Typhoons used the 4L60 4-speed automatic transmission. A BorgWarner 4472 all-wheel-drive transfer case splits torque with 35% of power going to the front and 65% of power to the rear wheels. Both trucks featured sport modifications to the standard suspensions. The Syclone was the first production truck to receive a 4-wheel anti-lock braking system. With this engine, the Syclone produces 280 hp (209 kW) and 350 lb⋅ft (475 N⋅m) of torque. The Syclone, when new, was capable of accelerating from 0–60 mph (0–97 km/h) in 4.3 seconds and could do a quarter-mile run in 13.4 seconds at 98 mph (158 km/h) according to Car and Driver's comparison test.
The Syclone and Typhoon's gauge cluster is the same one as used in the Pontiac Sunbird Turbo, which was discontinued in 1990, one year before the Syclone was introduced.
The 1991 Syclone was only available in black. For the upcoming 1992 production, a wider range of colors was to be offered; however, the Syclone was cancelled before full production could begin. In total, 2,998 Syclones were built. Out of the 2,998, only three were built in 1992. The first 1992 Syclone was used for DOT crash testing while the remaining two are privately owned.

Outstanding! Straight away it's unbeatable. The only issue is finding parts. I bought a new bit, but GMA has not kept supporting parts. But who cares? Did I mention the exhilarating feeling when you step on the go pedal?
