Stopping power is provided by AP Racing Big Brake kit, with 14.25-inch rotors in front and 13s in the rear. The 19-inch CCW wheels mount Michelin Pilot Sport 2 tires
Spent gases are expelled through a set of Stainless Works long-tube headers with 1.75-inch primaries and 3-inch collectors. They exit through a custom DuSold stainless steel X-style pipe with a pair of 3-inch Magnaflow mufflers. Horsepower has been dyno’d at 600 at the wheels, estimated at 725 at the crankshaft, using 93- octane fuel.
Backing this formidable powerplant is the stock T56 six-speed transmission, featuring a JHP Pro series billet shifter, McLeod RXT Street twin-disc clutch, and an aluminum flywheel. The stock IRS differential has been strengthened with a Harrop Sports differential cover, and BMR 300M axle stubs and CV axle shafts. Likewise, a custom DuSold strut tower brace, a set of BMR weld-in subframe connectors, and a skid plate were also added to enhance torsional stiffness and protect the differential.
The front and rear suspensions have been upgraded with a Pedders Track II system, which includes custom front and rear springs, shocks and swaybars. Though the specs on the system have not been released by the manufacturer, we do know that the swaybars are larger and significantly stiffer than the production units.

A Pioneer AVIC-X930BT in-dash navigation AV receiver with DVD playback, built-in Bluetooth, and 6.1-inch WVGA touchscreen display is used. The signal goes through a JL Audio HD900/5, five-channel system amplifier that produces 900 watts with variable front and rear crossover capability. It drives eight DLS 61⁄2 Ultimate Nordica component speakers and two sub-woofers.
An AP Racing six-piston Big Brake front kit with 14.25-inch cross-drilled and slotted two-piece rotors, and the matching AP Racing four-piston Big Brake rear kit with 13.00-inch cross-drilled and slotted two-piece rotors necessitated the use of 19-inch CCW forged one-piece wheels, which mount Michelin Pilot Sport 2 tires. The fronts are 245/35ZR19s on 9-inch-wide wheels, while the rears are 285/30ZR19s on 11-inch-wide wheels.
DuSold also handled the installation of the carbon fiber Banshee hood and the paintwork. The hood received Phantom Black PPG base/clear on the nostrils and extractors, as did the front and rear fascias. The grilles were painted satin black, as was the decklid, which also received a Reflective Concepts black arrowhead. David also retrofitted Jaguar XJS washers onto the wiper arms, so no holes had to be drilled in the carbon fiber hood.
With the project completed for now, Martin hit the road in his Goat. He reports, “It runs like a hamster on a wheel with a JATO pack strapped to its back, and it handles like a slot car!”
Does that mean he is finished with his GTO? Nope. Martin is looking toward the next phase of the build, which will likely include more power in the way of a 427-inch LSX with a TVS 2300 series supercharger. That should put the horsepower into four-digit territory. The question is, will that be enough for Martin?

A Magnuson MP112 supercharger and air-to-liquid intercooler are teamed up with a custom methanol injection system to maintain reasonable charge temperatures, while generating 17 psi of boost. A custom blower cam and 1.7:1 Yella Terra rockers operate the valves and Stainless Works headers route the spent gases away. A Ron Davis aluminum radiator with integral oil cooler and braided lines to the oil filter adapter keeps temps down on the road.
After gutting the interior,...
After gutting the interior, DynaMat insulation was installed before reinstalling seats, door panels, pillar panels and headliner, which now feature suede inserts. There are also custom fabricated electro-luminescent doorsill plates with milled lenses and red LED indirect lighting. An iPod connection is wired into the center console.
Other underhood enhancements...
Other underhood enhancements include a Kenne Bell Boost-a-Pump set to 50 percent, which increases voltage of fuel pump to 20.0. Custom computer calibration dyno tuning was handled by Patrick at Quality Motor-sports in Lewisville, Texas.
Not only does the area behind...
Not only does the area behind the grille mount the heat exchanger for the air-to-liquid intercooler, there is also a custom TIG-welded aluminum methanol injection tank, built by DuSold Enterprises. It holds 2.5 gallons, and the pump motor is located in the sump. Note the vertical fill tube accessible on the top of the core support.
