You can put the 2003 bumper on a 2002 car, but you will also need to replace the headlights with those from an 03-05 Neon and replace the hood with that of an 03-05 car.
car surges at stop signs, when i put it in neutral it levels off then put it back in gear it seems to be ok
yes but i think the 2002 and up is different mounts but essentially the same any dual can dodge/plymouth/chrisler dohc is the same as long as its form 2002 and up or 2001 and under

No, the years have to match.
Yes there is no difference in the two years 2001 was a carry over from 2001.
DO NOT PUT A NGC MOTOR (2003-2005) in anything but a NGC car!!! Your motor has a better compression ratio anyway. You will spend a minimum of atleast 1,000 man hours wiring and soldering a standalone engine managment together then a standard swap. Find any year between 96-2002... those will work just fine.
NO
