The flow numbers are on CGP somewhere....*use the search Luuuke*. There's many ways to get these cars into the low 12s and some are more expensive than others. If you're looking to do it cheaply N20 or Alky injection will get you there with the least amount of mods. Just save your penny's for a new trans as the stocker won't tolerate to many low 12 passes. If you're looking to do it w/out N20 or Alky you'll at least need an agressive cam, efficient IC and traction mods. I'm sure I've missed a couple things but this is what I can recall off the top of my head.
