A 6-velocity gearbox also will come standard. And if that’s not sufficient, an update was unveiled in December ’01 bringing 384Nm, another update arrived in late ’02 bringing 394Nm and Yet one more update in late ’04 introduced an enormous 412Nm. A slightly greater intercooler, a twin-scroll turbo, aluminium pistons and various interior mods are integrated in these working improvements. The present STi (with its substantially new nose) generates 422Nm of torque and, even now, peak electricity is deceptively detailed at 206kW. The twin-turbo Legacy vary continued nicely in the new millennium. Irrespective of a static compression ratio increase to 9:1, the existing B4 RSK sedan and GT-B wagon ongoing to produce 206kW/343Nm in manual guise. There were no changes towards the auto trans engine (rated at 191kW/319Nm) right up until the dual-turbo engine was axed in 2003.
