There really isn't one, but by shedding some weight of the car, spare, tools, lighter airbox, various plastics in the engine bay (Dan can help with that), lighter wheels, ecu-reflashed is around ~$700 but Dan thinks it's a bad idea, and he's the guru. Headers, new exhaust, will give a little more but nothing to brag about. Supercharger is the way to go for the most gain but isn't cheap. The two available now cost more than a decent new car. Unfortunately the most cost effective way is to trade up for an AMG SLK, which I am not ready for yet.
