A monster car fitted with a nearly stock-spec GT engine. It also has a triple-plate clutch and a six-speed dog-engagement gearbox, yet it can handle quarter-mile starts as well as street driving and cruising along the bay. At a drag start it easily spins to around 10,000 rpm in first gear; from 5,600 to 8,000 rpm it reportedly stays above 500 hp—an outrageous SR-powered tune. In September 1997, when the S14 was becoming the main Silvia, this car became the only S13 with an SR engine to reach 320 km/h.
