The OP was concerned with output, as in power, or HP/TQ of his platform (DSM). I really don't think that would warrent a change in platform, unless you want to upgrade to a newer, smoother, more comfortable, practical, better handling and braking, (uglier?), more expensive car. If power is the concern, the current platform really isn't holding back in my opinion.

And we cannot start a "v8 vs. 4bngr" arguement here.... We all know there really is no replacement for displacement. All the V8 guys with slow cars are too busy polishing their chrome or looking at a JCWhitney catalog...
