THE addition of a small IHI turbocharger boosts the 1.8-litre DOHC 16-valve engine's power output from 85kW at 5800rpm to 115kW at 5600rpm, and its torque from 154Nm at 4800rpm to 237Nm at 3600rpm. Along with the turbocharger comes heat shields, a dedicated front exhaust pipe and manifold, an intercooler and piping. The engine's control unit and fuel injectors have also been replaced with components engineered to suit turbocharged operation. Other modifications include revised spark plugs and the addition of an oil separator. The Sportivo requires premium unleaded fuel.
