I would not suggest any type of power adder for the 3.8 v6. The cylinder heads are prone to warping and blowing headgaskets when stock! Supposedly Ford fixed it a few years ago, but many are still having problems with them. If it is a weekend toy, yeah, forge ahead and explore new ground. If its your daily driver (hope so since its a 2002) you would be much better off selling the car and buying a V8.
