I'm neither so it seems as though there must be others no? I'm staying NA until the day comes when my weekend cruiser's engine is old and tired. Then I'll do it the right way by building an engine with parts that are made for boost. Not the cheap easy, fast food McDonalds way...but to each their own. I'll also have many supporting mods to harness the power levels I'll be looking for, ie. suspension trans, LT's etc. One thing for sure it won't be no stinkin 4.6 liter anymorethe only people that stay n/a are people that their mustang is just a way to get to work and people that are absolutely against f/i.
