Welcome abord.
The 660 isn't fuel injected, and the PC3 is for the fuel injected 700 (686).
If you're wanting a dependable build, go with the 686 kit, and run pump gas.
If you're just going to use it on trails, etc, drop a new piston in, new grind on the cam, and rejet. Very reliable, and a nice snappy punch over the factory specs.
The 2003 Raptor SE was black with the red frame.
