Finally, the turbo selected to provide the required breath is a Garrett T3, helped by an air / air intercooler. Delivering as standard 160 horsepower at 6000 rpm / min and a torque of 21.4 kgm at 3250 rpm / min for a weight of 970 kg, it allows performance worthy references the time as 1000 m DA in 27 "8, 0 to 100 km / h in 6" 4 and 220 km / h peak, plus a kick in the ass rather demon during acceleration.
