No Supra has a first gen B58. They are all B58TUs. 2 port vs 6 port has nothing to do with the engine generation.
Edit: oh- @razorlab already said that.
Stock supra doesn't trap 120 anywhere.. That's like 6-8mph faster than any stock supra I've seen. MPH/Trap is a function of horsepower, nothing else. Not driver ability, not 60', nothing. A stock supra doesn't go that fast, especially in 3000 DA, where you had on that day.
