you need to put your 2003 fuel rail and fuel injectors on the 02 motor and I believe thats it.

THis man is correct..just did the swap from a 02 eco to a 03 but wanted the 03 rail so changed the injectors and rail and computer. So for the 03-02 motor just swap the rail and injectors.

There's a 03 around here that runs perfectly fine with 02 motor, fuel rail and injectors... its not necessary to swap those things
