E5T
The flagship turbocharged, fuel-injected and non-intercooled variant of the E5 was the E5T. Released in 1983 and available only in Japan, the E5T utilized an IHI-supplied VJ1 turbocharger running approximately 0.5 bar (7 psi) to produce as much as 115 hp (85 kW) and 119 ft.lbf (162 Nm). Other notable advancements included an integrated knock sensor (supplied by Mitsubishi) and multi-point fuel injection as standard.
