Toyota built the 1988 Supra around a 3.0L inline-six in two forms — the 7M-GE and the 7M-GTE — paired with an automatic or one of two manual gearboxes, the W58 or the R154. Those combinations do not share one set of numbers, so the engine code and the gearbox matter as much as the model year when you are working on the car.
