I believe Ruf had a big impact on the tuners in Japan. It seems like those new modded ones are a modern interpretation of this model from the 70's ? It is one of the first RUF converted 911's with a huge turbo. I am not sure if it started as a turbo or whether a regular Carrera was converted. It has never been restored (full of rock chips and comes with a riveted rear fenders), but supposedly still good for 180 MPH.
