no the gts has a 2zz motor the gt has a 1zz, the 2zz can also be found in the matrix and the lotus, the 1zz if found in the corolla. there is about a 60hp difference between the motor on the dyno i've seen as much as 80hp difference. if your have ever driven an rsx type s it feels about the same as the gts celica. the auto gt if about as slow as it gets tho. i own and have built several celica's and i can tell you they are not all slush box's
