The fourth-generation Supra's engine is incredibly durable, proven by the fact that Hikari has used a stock bottom end for the race car. The shop was rather vague on the cylinder head work (telling us only that it was "top secret"), but we do know that it has HKS camshafts and AEM adjustable cam gears. Hanging off the exhaust ports is a Turbonetics T04-S04 turbo. Its support pieces include an HKS Racing wastegate and blow-off valve. Air is drawn through a Pipper X air cleaner and routed through a modified HKS intercooler. Exhaust gases exit via a 4-inch straight pipe. Additional fuel is provided by Bosch fuel pumps, RC Engineering injectors, and an SX fuel pressure regulator. Lording over the fuel and turbo systems is a Motec fuel management system. To solve the cooling problems encountered in the 1998 race season, Hikari has installed a Fluidyne four-core radiator and an oil cooler. Solid motor mounts lower the engine for an improved center of gravity and the transmission has been given a Tilton/HKS twin-disc clutch and a C's shifter.
About the only remaining mods are a MOMO racing seat, steering wheel, and pedals. To see how Hikari Works Racing's Supra does in 1999, tune your TV to the Speedvision network-all World Challenge races will be broadcast this year. You can find the most up-to-date racing schedule by checking SCCA's Web site: www.scca.com. Now, if you'll excuse me, I have to go pick up Heidi in my clapped-out Toyota Starlet.
