Toyota Supra JZA80 Specification Details: Engine, Horsepower, Transmission, Body, Oils and Parts

If you were around between the years 1978 and 2002, then you’re probably familiar with the Toyota Supra. It was a Japanese sports car that was manufactured during this timeframe. The body design of the Toyota Supra was inspired by the body of the Toyota Celica. This meant it had much wider and longer dimensions to it.

In late 1993, Toyota released another model of the Toyota Supra called the JZA80. It was also marketed under the name Toyota Supra SZ. The vehicle was fitted with the 2JZ-GTE engine, which is a second-generation model under the JZ engine series. There were two different configurations offered for this series. First, there was the 2JZ-GE model that is the normal engine configuration. Second, there was the 2JE-GTE model that is the turbocharged configuration.

People who care about driving faster would choose the turbocharger configuration over the basic configuration. Since the JZA80 was a sports vehicle, some people liked to use it in races as long as it had a 2JZ-GTE engine with a turbocharged configuration. As for everyone else who just wanted a flashy sports car to drive, they did just fine with the 2JZ-GE engine configuration.

Let’s examine the specifications of the engine, transmission, horsepower, body, parts, and oils of each type of configuration.
