Nah...A.D.D....is just a small part of it. I've been planning the 993 conversion for at least a couple of years, and collecting parts for it. I'm leaving the Carrera (aka Fat Bastard) as a CTR replica, and I'll just play with horsepower on it.
The original "Bastard" is the chassis getting the 993 conversion. I've got parts for a 73RS look if I decide one day to swap the 993 parts out. So Bastard will have two personalities, and I can bolt/un-bolt them on the chassis depending on how the mood strikes me

... so maybe not A.D.D....more like schizophrenic.
