The act of installing a chevrolet LS series V8 engine into a
car, normally Mazda RX-7s and Ford Mustangs. Usually frowned on by
internet "
car guys", despite the fact they make lots of power and are cheap.
"Oh my
God, an LS swap??? That's so unoriginal, you've ruined that RX-7! You've utterly destroyed the spirit of the
car!!!" 12 year old, who doesn't own a
car, on a forum.
