Even if it was not the favorite target of the 80s tuners, the Ferrari 308/328 nevertheless underwent some quite radical transformations by the various Koenigs, Zender, Laurenz and so on. Koenig was one of the very rare to put his hand to the 328, with a twin-turbo kit that increased the power to about 450 horsepower. The 328 Koenig had a modified bodywork, the molds of which still exist at the German workshop.
