1994 Toyota Supra Turbo - Powerhouse Supra

The factory stereo components were kept; however, the head unit was removed to add switches in its place while at the track. For street use, the head unit can be installed within five minutes for added driving pleasure, thanks to the removable switch panel. The roll cage was installed through the factory dashboard, with the required dash bar underneath. All points were tied to the structural frame and gussets were added underneath for added strength. The roll cage was outfitted with a Stroud window net; a Stroud parachute is on call at the rear. The parachute and window net are also removable for street use.

Under the hood, tinwork gives the Supra a custom look, not to mention it makes an excellent work surface for engine repair at the track. Removable panels in the tinwork allow access to the brakes, breather system, ignition system and wiring. An electronic panel was added to the roll cage above the driver seat to control basic functions such as electric fans, ignition system, water pump, MoTec engine management system and lights.

The factory front low beam headlights and rear taillights were maintained, along with turn signals for street use. PHR built custom aluminum seat mounts to secure Sparco EVO 2 seats and the required rear seat braces were added to the rear bar. The factory rear seat was kept in place for cosmetic purposes. The factory interior carpet was removed in favor of lightened black carpeting without noise-deadening material. A MoTec ADL digital dashboard is information central for the Toyota. The ADL dashboard is wired into the car in such a manner that the driver can activate the OEM cruise control switch to view different screens with different parameters. The factory steering column and steering wheel were left in place; however, PHR added a custom manual steering rack in order to remove the power steering unit for weight savings. Five-point safety harnesses were installed to keep the driver and passenger safely planted in the seat in the event of an accident. A Hurst shifter was installed on a removable plate for re-installation of the factory six-speed Getrag transmission for street use if manual gear selection is desired.

The transmission selection was a long decision process. In the end, a custom three-speed was constructed to harness the power. The transmission was enclosed in a titanium case (Ouch, that's gotta be big money!) with custom-designed gears. Everything was designed to propel the small-displacement 3.1-liter engine down the track in less than 9 seconds without the aid of nitrous, no easy task for a 3,200-lb car.

Power is output to a custom designed PHR 3.8-inch diameter carbon-fiber driveshaft fitted with Mark William's driveshaft ends. The factory Toyota rear end was kept, along with Toyota axles; changing the differential and axles would mean putting the car in the Outlaw Class, and swapping would affect street drivability. Therefore, PHR opted to stop the driveline modifications at the rear end, keeping the option open for the future. Shocks consist of Konis and Eibach coils and Ground Control coil-overs.
