The Ford Festiva was an unimpressive economy car, to say the least. It was small, good on gas for the time, and not sporty at all. Until Jay Leno's custom team, Chuck Beck and Rick Titus, got their hands on it and swapped out the engine for a Yamaha SHO V6 and mounted it in the rear. In this little samurai, it's all about power-to-weight. And nitrous.
