History
Porsche made its first and most significant modifications to the 930 in 1978, increasing the engine bore by 2mm (0.08in) to a total displacement of 3,300cc with the addition of an air-to-air intercooler. . With air-charged cooling, the intercooler helped to increase power up to 300 hp and 412 Nm but above all to maintain high reliability. The rear « whale tail » spoiler has been re-profiled and slightly raised to make room for the intercooler.

The suspension benefited from new anti-roll bars, stiffer shock absorbers and larger diameter rear torsion bars. Porsche has also upgraded the brakes with units similar to those used on the racing 917s. While the increase in displacement and the addition of an intercooler increased power and torque, these changes also increased the weight of the vehicle, particularly the engine, which contributed to a substantial change in the car’s handling from the previous 3.0. – liter models.
