I misquoted the cost of a new kit- its a little over 2 G's
As stated though you can find a used kit for less than a grand- or nitrous which is $500 or so for a 150 shot on a carb.
Or the self fabbed turbo setup- which most people can do with some back yard ingenuity and about $1000.
All of these are cost effective and will supply more power than your drivetrain should recieve... So look into buyig a built tranny next and a 12 bolt.
