TurboRX-6 turbine

I&D Automotive Technologies — « Investigate & Development » — built this PS13 Silvia as the second of a pair of full-turbine S13s aimed at outright Tsukuba lap time. A Tomei 2.2-litre SR20 on an RX-6 turbine makes 600 ps, carried by doubled spot welds, a widened track, fuel moved out of the rear overhang and aerodynamics worked out in detail.
