N/A Engines right??, NOT TURBO, i don't think is "THE BEST", but one of the bests for sure, there's some Engines from the integras Type "r"' and type "s" but let's don't forget the prelude TYPE "S" tough (220HP?), there's the S2K engine wich comes with 240 HP and 2.2l in it's very last version (2004). I think that the prelude in the late 90's yes was indeed one of the best N/A engines .. and still one of the Best engines availables .. even in this years.
