This thread was inspired by the "favorite engine" thread. It's a good question, but I thought I'd narrow it down a little...
So... what's your favorite 4-cylinder car or engine?
My answer:
Porsche 968 Turbo S
-305 hp
-369 lb-ft of torque (that's no typo!)
0-60 in 4.5 seconds, top speed at least 175mph!
