ok. I'll add to his question then. Can you throw a turbo on a 2002 3.8L Mustang without voiding the warranty? If yes, can it be done with used or junkyard parts? Are there any other inexpensive ways to get a little boost in power on the 3.8L without voiding the warranty? I was thinking maybe performance fuel injectors but idk if they even make a noticeable difference... Idk, I'm an old school engine guy. Can't do a 4-barrel carb on this sucker lol.
