I have an 05 pathfinder SE off road and an 09 Frontier SE CC and I finally got around to racing them and the truck won from a stop but the pathfider tore it up from a roll everytime. The pathfinder is bone stock and the truck only has a K&N intake. I was under the impression that they were the same drive train and the difference in the HP rating was because of fuel grades. Just curious if its the tranny or rear end or what??
