They did 3 different engines in that shape, the 2.5 1JZ-GTE, a 3.0 2JZ-GE and a 4.0
The 3.0 was apparently the one to have as basically the motor was the same as the Supra, although the size was the same, the stroke had been increased and bore reduced to give the car more torque than outright power to suit the type of car it was and the auto box they where fitted with.
In Japan the car is known as the Toyota Soarer, its on in Europe and US its known as Lexus (Luxury Export US
).
