2003 engine into 2006 Hyundai Accent

I was informed that they would interchange from 2001 up to 2006. Everything looks exactly the same with the exception of the ignition system coils versus the coil packs. All sensors match up, Everything. I am about to install the 2003 engine into the 2006 body in the morning, unless there really isnt anyway to rewire this ignition problem to work for me. They are the same engine, but I am not a professional, and would respect your opinion, although you are the only one that tells me that it wont work. Please save me a ton of work as I will stop with the install I planned on in the early morning if this is really not going to work for me. I will give you any more info that you need. Thank you very much for the help. I Finally got the locked up motor out, and have been prepping for the install, but havent begun it yet. If possible, I can be reached at 4807979197, name is Bill, thank you so much for the advice, all is on hold now.

Advice taken, thank you for saving me alot of work. Im going to do exactly that. Just in time too, Thank you so much.
