One of the keys to the Supra's performance puzzle is boost. In order to make reliable power and net prime-time e.t.s having a quick spooling turbo with efficient compressor and turbine wheels is critical. The earlier you can realize maximum boost pressure the longer you have full-power being applied to the tarmac. At the same boost level a more efficient compressor wheel creates more power than a less efficient wheel because the efficient wheel does not heat air as much when it compresses it. On the turbine side efficiency means moving air through the housing with as little back-up to the exhaust valves as possible. The Paisley Supra is pressurized by twin HKS GT3037 turbos with Paisley-spec housings and other "tricks" performed to both the hot and cold side of the turbo. "When we sell twin-turbo kits we incorporate some of our tweaks to get the most out of the kit," says Craig. A HKS stainless-steel manifold positions the turbos and maximum boost is regulated to 26 psi via twin HKS wastegates and twin HKS boost controllers. Since Paisley Automotive has such a close working relationship with HKS the Supra was used as a R&D testbed and the two units, an EVC IV and EVC EZ, were comparison tested. The charge air is chilled in a massive air-to-air front-mount intercooler. For added pep a modest 30-horse, single-fogger NOS nitrous system has been plumbed in to mist extra power on the top end. The ignition has been fortified for forced induction and nitrous with a HKS Twin Power Ignition Ampifier and HKS plugs.

Surprisingly, the 2JZ-GTE inline six runs factory stock internals. The valves and combustion chambers are also stock. The only additions in the valvetrain are HKS 264-degree bumpsticks and adjustable cam gears. The Paisley Supra is pressurized by twin HKS GT3037 turbos with Paisley-spec housings and other "tricks" performed to both the hot and cold side of the turbo. A HKS stainless-steel manifold positions the turbos and maximum boost is regulated to 26 psi via twin HKS wastegates and twin HKS boost controllers.
Working with a stock-based engine it is critical that one makes as much use of the power being generated as possible. To properly harness and transfer the Supra's power to the pavement the Paisley crew decided to go take the next step. "C&F Racecars in Pleasant Valley, New York are the premier chassis builders in the Tri-State area and they delivered us a car that has performed flawlessly from Day One," says Craig. "The car drives straight and handles great. We delivered the car to C&F with the intention of going back half. Once the Supra was back at our shop we were looking at it and decided that the big rotors had to go in order to fit the skinny front tires I wanted to use. We decided to run the cage to the top of the framerail and make mounting pads for aftermarket struts on the cage. The original steering rack was replaced with a Wilwood unit and custom fully-adjustable control arms were mounted in place of the factory-issue units." The chassis, which is certified to 7.5 seconds, runs high-performance suspension components to bring it all together. Up front, Strange adjustable shocks and springs are on call while the rear features Koni coilovers and a four-link suspension that locates a prepped Ford 9-inch rearend. A custom C&F fabricated two-inch sway bar keeps the car pointed down the strip. A pair of 14.5x33 Goodyear slicks are wrapped around Weld Racing 15x14 AlumaStar alloys to provide the final link in the traction chain. To look the part, the body has been accented with a Bee Racing rear wing and Wings West front lip spoiler.

Craig pilots the Supra from a Butler lightweight racing seat and he's surrounded by a C&F Racecars-built cage that's approved to 7.5 seconds. The fact that the engine management system is a programmed stock ECU and HKS piggyback computers instead of a big-buck stand-alone system is testimony to the car's mission statement. That statement supports using aftermarket components to prove that a high degree of performance can be extracted from a stock-based powerplant for a reasonable cost. Paisley hopes to attract more people to the sport of import drag racing. A high-tech carbon-composite NOS bottle rides shotgun and provides a mist of go juice on the top end.
