Actually with a good driver and a manual trans, the base(3000GT)/ES can run mid-high 14's (as proven by WICKEDDREW and some other guys who have run 14.7s, drew ran a 14.4 *correct me if I'm wrong* with his only mod being a K&N, figure it adds 5 horsepower, so he could have ran a 14.5-6 stock.).. as for the SOHC, I haven't really seen any quarter mile times from them, but i'd say high 15's wouldn't be too hard to hit. They may have less horsepower, but I don't think they weigh 3200.. I think it's around 3000 maybe. The SOHCs have one thing that helps them a lot, and that's the torque. People have said that from 0-60 the SOHC keeps up with the DOHC despite the 60 hp difference, but after that the DOHC walks away... needless to say I believe that both cars could get up to 150.. the DOHC getting there much quicker I'm sure.. the gearing and power is there. And if you don't believe the people who have stated they've gotten 150 in their N/As, then that's your problem
