USDM Engine Specifications
In the US and Canada, the '94-99 Celica was produced with one of two engines. The ST has the 7A-FE engine, while the GT and the Canadian GT-S have the 5S-FE engine in them. The ST's 7A-FE was modified slightly in 1996 to incorporate OBD II, which is a system to control the engine more completely, so that emissions are better. This change dropped the horsepower by 5 horsepower and increased the torque by 2 lbs.-ft. of torque. The specifications of these engines are below.
