Engine Swap on a V6 2003 Mustang.
Ok, so I'm new at this and was looking for some advise. Im looking to swap out my engine for a 5.4L ford engine. I need to know the details on what all I should change out. Also if anyone here has done it maybe how you've liked it and would recommended it. I'm hoping to do it with in the next 2weeks so I would really appriciate the input. Thank you

WELCOME TO MF'S
I was planning on dropping in a 32 valve motor in place of my 16 valve motor this summer. I was talking to my mechanic yesterday and our conversation got me thinking. If I swap engines I also have to change the ECU to the new engines ECU. The new engines ECU will register as a different vehicle when I do the emissions test. All ford ECU modules have the vehicle's VIN logged into it. My mechanic has swapped engines for guys before but they only ran their mustangs under 5000 miles a year to keep it emissions exempt to avoid this problem. Any thoughts...
