Only two of Toyota’s sports models—the Soarer in the rear of the Z20 and the Supra A70—were equipped with the 3.0-liter turbo 7M-GTE engine, which was assembled at a factory in Japan between 1986 and 1992. This engine was available in racing versions with up to 580 horsepower under the 7M-GTEU designation.
The engines 5M-EU, 5M-GE, and 7M-GE are also part of the M family.
The engine was mounted on:
- Toyota Soarer 2 (Z20) in 1986 – 1991;
- Toyota Supra 3 (A70) in 1986 – 1992.

Disadvantages of the 7M-GTE engine
A cylinder head gasket failure near the sixth cylinder is a common engine issue.
Grinding a metal package’s mating surface is one way to solve the problem.
Additionally, the inadequate performance of the oil pump reduces the engine resource.
The antiquated and erratic ignition system is another flaw.
The valves must be adjusted using a variety of washers every 50,000 kilometers.
