In motorsports- a garf motor is an engine put together with JUNK/poor quality parts and components.
Usually such engines run very poorly, yet the owner thinks they're the "cat's ass"
"Stevie and I put together this motor one time with parts out of a garbage can- what a garf motor that was!"

"Every time Larry and I go to the drag-strip, there are a bunch of white-trash dudes with garf motors!"

"Look at that hill billy with his Mustang and garf motor..."
