Stephen Floyd’s Single Turbocharged Gotta Have It Green 2003 Mustang Cobra
Gotta Have a Terminator
Every year at Mustang Week there are certain cars everyone remembers. At the end of each day conversations turn to asking your friends if they saw the such-and-such Mustang in the color they have never seen and with the wheels everyone wishes they had. We know because we are the same way. Another good thing about Mustang Week is if you see a car early in the week, there is a good chance you will see it later as well.
In the case of this Cobra, if memory serves, we initially saw the car at the Meet-N-Greet but couldn’t find the owner. Then we saw the car again later in the week and took to social media for help. Through our network of Mustang friends we were able to contact the owner and arrange for the photo shoot you see here.
Stephen Floyd has owned and built several Mustangs in his time, among them an aluminum-headed Fox with a Vortech back in the late 1990s, and a 1996 Mystic Cobra that made 632 rwhp back in 2001. His 2004 Mystichrome made it onto the pages of this magazine in the May 2005 issue (“Six-Speed SlaughterFest”). He has owned numerous Terminators and a 2014 Shelby GT500. He knows how to build them.
This particular Cobra he bought from a friend of a friend. The car had a stock engine, but with twin turbochargers, cheap seats, and, according to Floyd, “The ugliest wheels ever.” Floyd set about disassembling the car to get it ready for its reintroduction. Once he had the car taken apart, he sent it over to Taylor’s Paint & Body in Rocky Mount, Virginia. The body itself was left alone, save for removing the antenna, but the color was going to be a dramatic change from the factory Dark Shadow Gray. Though Floyd says he is not a fan of bright cars, Taylor’s applied several coats of BASF Gotta Have It Green to the Cobra before it left the paint booth.
Once Floyd had the car back in his possession, he set about reassembling the car, but with a few changes to go along with the fresh paint. Of course the wheels had to change, since Floyd obviously wasn’t a fan of the ones that came on the car. To put even more of his own fingerprint on the car, he added Weld V-Series wheels up front with Mickey Thompson Sportsman tires, and Champion beadlock wheels out back with ET Street radials.
Yeah, this Cobra looks amazing, but Floyd didn’t build it to be a show queen. “I built the car to race,” he says. “I have had several low six-second eighth-mile cars, but I look forward to taking this one quite a bit further.”
To make sure that was possible, everything underneath is ready to race. Up front are a QA1 tubular K-member and A-arms, Strange Engineering 10-way adjustable struts, a Flaming River manual steering rack, and Maximum Motorsports caster/camber plates. Out back is a solid-axle 8.8 with 9-inch ends, Moser 31-spline axles, and a Detroit Locker differential. For rear suspension, Team Z was called upon for its adjustable upper and lower control arms and antiroll bar. Viking double-adjustable shocks reside out back, while other chassis improvements include subframe connectors and reinforced torque boxes. Stock Cobra brakes with Baer Eradispeed rotors live up front, while Wilwood discs live out back, all fed brake fluid via a Wilwood master cylinder and proportioning valve.
To help Floyd take the car quite a bit further is a built Four-Valve engine starting with a Teksid aluminum block with a steel crank, Manley billet I-beam connecting rods, and Diamond Racing pistons. A Melling 10227 oil pump with billet gears feeds the beast, while a DSS aluminum stud girdle helps keep everything sturdy. A Moroso aluminum oil pan keeps that lifeblood contained and ready. A pair of stock heads was sent to Fox Lake Power Products for a full CNC port job. Also up top are Ferrea valves and Comp Cams 106500 camshafts. The crown jewel of the engine is a Hogan’s sheetmetal intake with an Accufab single-blade throttle-body, and Billet Atomizer 225 fuel injectors, which are fed via a Fore Innovations triple pump that featuring Walbro 465s.
The turbo of Floyd’s choice is a BorgWarner 82mm single. The handiwork of Mark Gongloff from Halfast Fab can be seen through the intake tubing. Floyd sourced Holley for one of its Dominator EFI systems and Smart Coils. Peter Harrell is the one on the keyboard, handling the car’s tune. Behind the built Four-Valve modular are a Lentech 4R70W transmission with the company’s valve body and converter, a Hurst Quarter Stick shifter, and a B&M cooler. An aluminum driveshaft sends power to the back.
Though Floyd built the car to race, with a full interior and A/C, he says it is not uncommon to take the family out on the weekends. “However, once the tune is dialed in I plan to start racing it as time allows.”
As of this writing, time hasn’t been on Floyd’s side, but soon enough this Gotta Have It Green Terminator will be hurting feelings at the track.
