From what I've read in magazines, the trans your car currently has comes with an extremely short 1st gear and can handle maybe 300 lf-ft of torque. The recent thread showing a hillbilly slipper clutch may be of interest. Swaps to some other T5 might also be worth looking into.
I hate to say this because I like the concept of the 3.8 with a 5 speed in that car, but I would think for a grand or so you could have a rebuilt automatic that would be a good fit for your goals with this car.
