From the rumors going around right now, the top motor available in the Dart will be the 2.4l in the r/t. I'm sure they'll do a SRT-4 version, but I doubt they would put the v6 in it. Judging by Dodge's track record with small cars (omni, neon) I doubt that after the aftermarket gets ahold of it, you'll even need a v6. People did some really impressive things with the Neons.
