Toyota M Engine - 7M-GTE

The turbocharged 7M-GTE was produced from 1986 to 1992. Output was 173 kW (232 hp) at 5600 rpm and 325 N·m (240 ft·lb) at 4000 rpm for most 5 psi (0.34 bar) versions. It was Toyota's top performance engine until it was replaced by the 1JZ-GTE.

A special 7M-GTEU version, with a modified CT26 high-flow turbocharger and large volume intercooler, pushed output to 267 hp (199 kW) at 5600 rpm and 358 N·m (264 ft·lb) at 4400 rpm. This was used only in the racing homologation Toyota Supra Turbo A road and race cars. The Turbo A models also measured air based on manifold pressure rather than using an air flow meter, had a larger intercooler, larger throttle body, optimized CT-26 turbo, and various other differences. It was the fastest Japanese car at the time. The homologation was for the Group A series. The Group A Supra with a 7M-GTE and CT26 turbo produced 433 kW (580 bhp).
