The Festiva can be made into quite a screamer with a bolt in engine swap from a Capri XR2 Turbo or a 323 GTX. It's called a B6 turbo engine ( I think), and it even bolts to the Festiva's gear box. Look up Fastiva on Google and you should see a few. If you want to see some in their original Korean market, look up the Kia Pride. Yes, it's a car with an engine built by Mazda, a body and assembly by Kia and sold as a Ford. The Capri was also an odd mix of an Australian built car with a Japanese engine sold as a Ford. Oh, and the engine will also fit an Escort GT or a Protege, as they are the same car underneath, and had non turbo versions of that engine stock.
The Geo Storm is essentially a Isuzu Impulse, and those were available with an AWD turbo drivetrain, so it too has possibilities.
