Now kids, pay attention...street racing 101 is in session
DSM is an abbreviation for Diamond Star Motors referring to the union between Mitsubishi and Chrylser. The offpsring of that arrangement include such ricer specials as the Mitsubishi Eclipse, Plymouth Laser, Eagle Talon and also the Mitsubishi 3000GT and Dodge Stealth twins.
That 'Vette in that video is not a ZO6 but rather a ~700 HP Lingenfelter Z-51 vette (C-4). It's a 383 stroker motor with god knows what else done to it but that's a standard package from John.
A 13 second car is not "average." It's fairly quick compared to the usual brand of ricer civics and integras (turbo variations aside). A low 13 second car will eat any stock Z-28 or Rustang GT for breakfast, lunch and dinner.
If you're in the 11's or better on street tires, then it's bad ass
