For Martin McGuire of Downers Grove, Illinois, the GMC Syclone was the truck of his dreams. Martin told us, "I fell in love with the Syclone in 1991, and my goal was to build the baddest S-10 ever." To accomplish that goal, Martin had to first acquire the correct vehicle. In August of 2001, he took one step closer to his goal after pulling the trigger on a 1992 GMC Sonoma GT. Being one of only 806 built, this truck was already unique, but Martin wanted to make it a true one-of-a-kind with performance the GM engineers could only dream about.

The first thing Martin needed to do was bring the truck down in height. Competition Fabrication, in Maple Park, Illinois, was in charge of the altitude adjustment. The first thing was to shed the frame of the body so that the frame could be modified. With added strength and rigidity being the end goal, the front half of the frame was boxed and tubular crossmembers were welded in. Next, the factory front suspension components were swapped out for a set of Ridetech upper and lower control arms, Belltech lowering spindles, and dual-adjustable Shockwaves. For the rear setup, a custom four-link was fabricated and installed along with another pair of Ridetech Shockwaves. To control body roll, Belltech front and rear sway bars were installed. Proper rolling stock is vital to match the design theme of any build, and Martin chose a set of custom-painted Billet Specialties SLG20 18x8-inch and 20x10-inch wheels wrapped in BFGoodrich KDW2 rubber. The brake system was completely upgraded to a full Wilwood system including a dual-reservoir master cylinder, Wilwood 14-inch rotors, and Superlite calipers on all four corners. The next thing Marty had to do was make the truck faster than the factory 4.3L Sonoma GT could ever propel the truck.

Absolutely stunning, Recovery Room bathed the interior in tan leather and added a prototype feel to the truck by paying close attention to the details, like incorporating the headrests into the rollbar. Four-point harnesses ensure Martin stays put when muscling the truck around a track.

Calling on the help of Stan Martin of Rogers, Arkansas, the newly bored 4.7L Bow Tie block was assembled with a new Crower rotating assembly with forged 9:1 pistons and Crane camshaft. ARP bolts ensure the entire engine stays intact with all of the boost being thrown at it. A Cloyes timing chain kit keeps everything spinning in time while new lifters, rockers, and valves were installed in the aluminum Pontiac 449 heads. For even more power, Martin had a pair of Precision Turbo GT3255E turbos and tubing fabricated, installed and wrapped in DEI heat wrap. The compressed air from the twin-turbos feeds into a custom sheetmetal intercooler, through the 75mm Wilson throttle body and into the Hogan sheetmetal intake. A Billet Specialties serpentine belt kit adds a touch of show to all of the go inside the engine compartment. The power is transferred to the ground via a 4L80E, which was rebuilt by Mark Bowler of Bowler Transmissions, in Lawrenceville, Illinois. This sends the power to the Currie 9-inch rearend with 3.70 gears and a True Trac. After updating the Sonoma's stance and go-fast velocity, the next order of business was to completely makeover the exterior.
