Lots of questions about 02 GT or 03 GT

[Bobu]

Ok, in about 6 months I'm getting either a 2002 GT w/ Premium package or a 2003 with same set up.

I've had years of experience with older Ford smallblock V8s ... 289s and 302s ... some experience with the larger FE series (390s, 427s, 428s) .... I have no experience with the new 4.6L modular.

Will be purchasing one as I said in about 6 months. Questions:

What are the easiest and least expensive mods to go with first. I've already decided that I'll have a set of springs installed and a new exhaust ... most likely Bassani with no cats ... either magnaflows or flo-masters behind those. After that I have no idea what works best or doesn't ... and I'm not really interested in a lot of modification that could cause serious warranty issues until the warranty runs out.

Another, what will be the difference if any between the powerplant of the 02 GT and the 03 GT ??
