For any different engine you're throwing in you're gonna need an ECU tune or swap I would look up the specs of both engines and try to find diagrams if you can, it will usually say what connectors each engine uses. Where there is a will there is a way and these are similar engines so it should be easier than something crazy like an ls4 conversion. If you haven't already it's always good to add some handling upgrades before you go for a swap coil overs and sway bars will make your car even faster in most applications because they improve your ability to control the car. Best of luck and sorry I can't answer the question directly.
