I donno... I've seen some bad ass deisels. It's never really about what you have it's about how much money you can throw at it. I had a buddy with a turbo gsr integra crush a viper, and I've had my ass handed to me by a cummins in my gf's 09 si. Which I couldn't keep up with until recently. Yea it doesn't really "feel" fast except in first gear when you crack vtech, but it revs like a freakin street bike and doesn't weigh anything. A modded deisel with 12 1300 ft lb's isn't going to have a problem pullin an 8000 pound truck around. But I guess it's all about weight gears and power, just need a good combo..
