the best 0-60 times of a usdm 5th gens are gonna be from the si...which is a hatchback with the d16z6 vtec engine. I dont know where cardiff is...europe? but the specs are all different over there. But i believe everywhere but japan you could only get 5th gens with a single over head cam...and the d16z6 was the biggest and had intake vtec. In america you can get an ex sedan or coupe or an si hatch with that engine and obviously the hatch will be the lightest...As for the 5th gens being the fastest, maybe you have heard they are the lightest...which still isnt necessarily true because ive heard you can strip out and 6th gen hatch and it will weigh about the same as a 5th gen. But honestly 5th gens are the way to go, because they are plentiful, easy to come by, have a huge aftermarket thats easy on the wallet and they have wishbone suspension so they are quite agile.
