there a lot of adapterplates available for those bugs , there was one company here that made them to fit a alfa romeo alfasud engine to the gearbox , thats a flat 4 watercooled engine that realy likes to rev
........ come to think of it a subaru impreza has a flat 4 watercooled too only a LOT more powerfull and with a huge turbo
there was a rendering made of the beetle in the english streetmachine magazine wish looked realy cool , the dimentions dont quite match the originals though (the doors are higher under the windows the sill sits lower )
now theres a challenge in sheetmetal
