Yours is the same 2.4L motor as the SRT-4 and PT Cruiser Turbo, just without the turbo and higher compression and this and that. See, there's more than you think to your motor. The 6g72 V6 isn't that great by itself bro, ask the guys who have them. They even turbo that motor or supercharge it, so swapping that motor into your chasis is counterproductive IMO.
You can also keep your motor and get a turbo for it, but you would have to either modify a header with a turbo flange and wastegate or find the turbo 2.4L header and intake manifold. There may even be a "kit" for it...I don't know enough about your motor though, other than a guy with an Avenger using one and getting parts from the other two vehicles to turbo it = 2.4L turbo Avenger.
*edit*
Here's some
good info on the 2.4L
