Yeah....having a great platform to start with , but i dont know what i want !!

Srt 2.4 with. 60 mm turbo and meth injection. Manual trans from a Jeep Liberty and IRS from a mustang cobra/Lincoln mkiii. Keep the mopar front suspension with bigger T bars, reinforced LCA, and reinforced core support.

450 WHP, manual trans, independent rear suspension. With the short wheelbase and all the weight savings from the 4 cyl, I bet it would be incredibly well balanced and fun as hell.
