A stage 5 Z with $2k into it can run mid 12's, but a stage X + NOS Z w/$10k into it runs 12.0's. Doesn't make ANY SENSE. You know what's completely off the subject, but really gets me? A BPU Supra, which in the Supra world is like uquivalent to a stage 3 TTZ, can run high 11's, no NOS. GOD DAMN, THAT'S what I call taking well to mods.
