The 3.8 is by far a way more fun and sporty driver in stock form. I also find with the 3.8 simple bolt ons can really wake the car up. Cold Air Intake, Exhaust, Headers will dramatically increase the feel as well. As for the 2.0 in it's stock form I've found it to be a little sluggish on the bottom end but up top it seems to pull pretty hard. We'll see once Lindsey gets and intake and exhaust on her 2.0 how well it takes to upgrades.
Also in the future expect a nice supercharger kit for the 3.8 and then you'll be cranking away around 400-450whp!
