Question on an engine swap of a 2000 Mustang?
Not worth your money. If you were to put the supercharged 4.6L from the 03-04 cobra into a v6 body, you would have some issues. First, the v6 tranny would not be able to handle the increase in power from 195HP to ~390HP. So, a trans upgrade is a must. Also, you would have to weld in the new motor mounts because the v6 ones arent in the same places. You would have to swap out the entire rear to handle the extra power as well. The entire exhaust would have to be done. Also, upgraded suspension to handle the extra weight from all those new parts. Plus the fact that the v6 frame probably wont be able to handle the double in power.
Save yourself tons of money and A LOT of time and just buy a cobra
