Im finanly about to pay my car off and with about 130k plus on the motor Im thinking that it would be a good idea to get a new motor. I've done some searching on the forum to find out how easy it would be to swap out my regular duratec to an SVT engine. I was suprise to see that 99% of members recomended going with a 3.0L, because it was easier and probably cheaper vs a svt 2.5L. However I have a few questions,

1st if I go with a 3.0 does it mean I don't have to swap the computer? (that would be great because the whole key, door locks, and ingnition would be a pain)

2nd if were going 3.0 would the 3.0 duratec from the mazda 6 work? I know this would mean swaping out the computer, key, locks, the whole nine but if Im gonna swap might as well go big.

3rd if I go with a 3.0 (mazdas or fords) can I still put the Street Flight trubo kit on it cause that's something I plan on doing in the future?

I know my little novel is knida long but I want to make sure that I plan this out well, because I want to do this rigth. Any input would be great, I surrender myself to the Contour Gurus.

1)use the stock PCM
2)No.
3)Yes.

You would not be able to use the Mazda6 3.0L due to the Sequential Valve Timing, the ECU is also CAN-protocol. S-VT requires signals from the ECU to activate oil control valves to advance or retard the intake cams a good number of degrees.
