I inherited a trike from my grandfather that was built from the front end of an audi but I'm having trouble pinpointing which exact motor I have to see if a turbo is an option. Any help would be awesome cause its sentimental to me and I would love to make it a drag strip toy to honor my grandfather and a turbo is the only thing I can afford and do myself but if it's not worth it i dont want to destroy it.

 

any updates ?
