The base engine produced 110hp at 4700 rpm and 130 foot/pounds of torque at 3000 rpm. The more energetic GT powerplant added a Mitsubishi/IHI turbocharger and an intercooler to the intake tract, as well as a knock sensor and electronic boost control to the engine-control system. The entire arrangement was calibrated to provide midrange output; the maximum boost pressure rises to 9.3 psi in the vicinity of 3000 rpm, tapering down to 7.3 psi elsewhere.
