There were two major changes to the car that happened between 1987 and 1991. The early models, known as the "Zenki" (前期) generation, were introduced in 1987. The engines in this generation were less powerful compared to the later versions, with the naturally-aspirated 4A-GE producing and of torque, the same power figures as the first generation 4A-GE in net output. The supercharged 4A-GZE on the other hand produces and of torque, the same power figures as the engine found in the supercharged Toyota MR2. The 4A-GE engines in this generation were late "bigport" versions, denoted by the red-and-black lettering on the cam covers. These engines (aside from the 4A-GZE) retained the T-VIS intake system from the early "bigport" versions found in the previous AE86 models, among other minor changes. Other distinct features on the Zenki models included different front bumpers for the Levin's front end, having a different design with a small upper grille that extends to both ends of the bumper. The Trueno had a front bumper design similar to the preceding facelifted AE86, and had combo lights near the headlights and bumpers.
