Default Dropping 03 GT engine in my 98 GT

Ok got a motor coming tomorrow, its out of a 2003 mustang GT, with only 47k miles on it.

I dont have time to search and get a list of what i need to swap the motor in my 98 GT. Does anyone have a list or some links of this..maybe with a write up? I need to know what parts i need to change to make this motor work.

So if anyone has anything, please link asap. I really appreciate it.

Ohh and the new motor is missing a starter, alternator, and a compressor..will the ones on my 98 GT work? thanks so much.

its just like swapping the long block in. its no big deal. all your accessories will work. you will need to get a tune to get the most available power out it.
the pi swap was the best thing i've done.

the clutch is up to you but yours will work with the new motor if thats the question.

i did headers and a new clutch in mine since i was already in there.

Thanks for the help, i think im just going to replace the whole clutch while its all apart, since my throw out bearing started squeaking before the motor blew.

I wish i could afford headers right now, it would be the perfect time.

Sweetness, got the motor coming tomorrow and gonna put it in on saturday, hopefully have it up and running by sunday. Gonna stick with the old clutch, its only 1.5 years old. No one has a new one in stock and im not waiting 5 days for one to get here..so im just gonna replace the throw out bearing.

Im pretty excited, just dont know how much of a difference there will be.
