Each Stage is a one year plan budgeting roughly $1200 each year ($100 a month) on your car's performance. Furthermore, each step in a Stage is something you should be able to accomplish in a typical weekend, or a partial week at worst. Depending on your skills as a Shade tree mechanic, some of this work you may wish to farm out to your Machinist, Exhaust Shop, or Mechanic. NOTHING is so difficult that the average person with basic skills cannot accomplish by himself.
All Emissions are retained in this Buildup and are designed towards passing California Emissions testing. Since California has the toughest testing in the U.S. this buildup should pass any states emissions laws. This does NOT mean however, that it will. You MUST check you local state laws to verify that there are no idiosyncrasies that will cause you to fail. I won't even try to stay on top of each states emissions laws, so I will not guarantee this buildup in ANY state! (Hey things change each year !)
