If you are on your P's, then to stay legal your car can't have any mods.
A rotary in a Datto would be considered a fairly serious mod by even the most stupid cop.
As you aren't licensed to drive such a car, your insurance would be immediately void, and if you should hurt anyone while driving, you'll be paying their medical bills for the rest of your life.
I might sound like a killjoy, but I'm sure your parents don't want you to screw up your life just for a few burnouts and traffic light races.
Buy a trailer, build a track car, and drag it around in a 6 cylinder falcodore.
