does it require a retune/tune after the swap?

I would think its not absolutely required....

the MAF will adjust for air flow etc etc, the timing tables probably arent much different from a npi to a pi motor as long as you dont make any drastic changes to the motor

Oh.. ok I gotcha.

Ok both cars are 5 speeds. And yea I am going with the 04 tranny too. That's the main reason for the swap I just put another motor in and found out the tranny needs work so I am just going to do a full swap motor and tranny to the 04 pi motor. I am new on here I've not really found out how to search for stuff yet. I've googled it and not really found any answers the best I found was that someone said they had to change some sincers but never said what sincers.

I called today I am going to go and get my ecu flashed to get the most out of the 04 motor. I was told I can get it done for $95.00 not too bad then tune with all the add ons.

I would think the swap should be pretty much direct other than swapping over your 96 timing cover and accessories... manual trans should work fine since its mechanical.

I would just pick up sct handheld tuner if I were you...maybe find one used for cheap so you can always upgrade to a custom tune in the future. They are usually loaded with generic tunes and you can run a 93 octane tune to pick up some power as well.

yea I know I am going to have to tune it I have alot of add ons I am going to take off my motor now and add to the 04 and when its out I am thinking about adding some long tube headers before it gos in too. When it gos in I am going to take it and flash the ecu and then get the tuner and do that. Well thanks for the help. If you can think of anything else I need or should know just let me know thanks again.

when putting the longtubes in, you will have to lay them in position before putting the motor in, then bolt them up afterwards, and it will still be annoying as hell and will require 2 people

Really ? Well I never would of guessed that but thanks for the tip. This is my first mustang I had that I'm doing anything to so I'm learning as I go. But that's for that info. Is there a good way to do the right side there not much room there ?

You will probably need to leave the motor lifted up some to get to all of the bolts. And if I remember right, the drivers side has 1 nut that you have to put on as you slide the header onto the bolts cause the bolt ends up touching the header after it is tightened completely up, but my buddy had BBKs, not sure if other headers are different. They will probably take a few hours to do, and a set of ratcheting wrenches will save you a LOT of time
