The S2000 isn't a great car for drag racing. Stock ones have trouble breaking into the 13's, one with i/h/e is not going to run a 12.5. Additionally you would need a full 1/4 mile for the S2000 to catch up the the Firebird as it would get killed off the line. Badly.

The guy with the S2000 needs to sell it for not appreciating its amazing chassis and be banished to an '87 Mustang with a cigarette-burned interior.

He's definitely talking out of his ass about that dyno.
