shallower oil pan, and round intake runners. 1983–1985.5 Supra 5M-GE had 0- to 5-volt output AFM's and TCCS. 1984–1985.5 Supra 5M-GE had 7-rib serpentine accessory drive belts, 60 amp alternator, round-tooth camshaft belts, 9.2:1 compression ratio, knock sensor, deeper oil pan, and D-shaped intake runners. 6M-GE Toyota increased the 5M-GE's stroke to to create the 6M-GE. This necessitated the fitment of larger diameter intake runners versus . Only produced in 12-valve (2 valves per cylinder) DOHC/fuel-injected versions, it was available as the 6M-GE and Japan-spec 6M-GEU from 1984 through 1987. The 6M engine used the same crank, machined to accept a different torsional damper, as the 1986–1989 7M-GE and 7M-GTE engines; this fact is witnessed by the designation "6M" stamped on the counterweight of the crank on the earlier 1986–1988 7M engines. Output was at 5,600 rpm and at 4,400 rpm. The 6M-GEU is usually the lower powered variant of 6M engines, due to more restrictive exhaust and increased emissions-control hardware. Even though it was never offered in US-market vehicles, it is sometimes imported from countries where it was available and transplanted into US-market Celica Supras and MX63 and MX73 Cressidas, since it is externally identical to the 5M-GE. Applications (calendar years): Toyota Crown Toyota Soarer (MZ12) 7M-GE The Toyota 7M-GE introduced in the early months of 1986 is a 24-valve (4 valves per cylinder) DOHC/fuel-injected engine. The valves are spaced at a performance-oriented 50° angle. Cylinder bore and stroke is . The 7M-GE was produced from 1986 through 1992. Output was at 6,000 rpm and at 3,600 rpm.

Output was at 5,600 rpm and at 3,200 rpm for most versions. It was Toyota's top performance engine until it was replaced by the JZ-series engines. Toyota produced a variant of the existing Japanese-market 7M-GTEU which featured a modified CT26 high-flow turbocharger and large volume intercooler, pushed output to at 5,600 rpm and at 4,400 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
