The engine was upgraded to dual overhead cams and four valves per cylinder in 1993.
Due to this and other refinements, this engine produced 211 PS (155 kW; 208 hp) for the regular 1993 Alfa Romeo 164, with 230 PS (169 kW; 227 hp) and 276 N⋅m (204 lbf⋅ft) in the 164 QV with its engine producing 232 PS (171 kW; 229 hp) on the Q4 model which in its final production run in 1996, it got reduced to 228 PS (168 kW; 225 hp) but with increased torque.
The final run of 3.0 V6 engines in the GTV, Spider and 166 range, produced 218–220 PS (160–162 kW; 215–217 hp) in the Euro 3-compliant version.
The engine has a bore and stroke of 93 mm × 72.6 mm (3.66 in × 2.86 in), the same as the two-valve.
