I personally own a 2.0 turbo and I will argue that a 4cyl turbo is about equivalent to a V8 but I will also argue that a V8 with a power adder, if built right, is one of the finer things in life and I don't think that there is anything that will ever change that. Displacement and wieght are the two factors you look at to make a car fast, and if you don't have the displacement like me you must find something to make up for that, but when you already have a big motor and then boost or juice it is just plain nasty. I really can't stand the import guys that loose to a mustang and then try saying things like "unplug 4 of your spark plugs then lets race"..... that is nothing other than stupidity. Like I said before all cars are different and if a car is respectable then thats what it is straight up.
