stock - 215hp. don't know the torque or 0-60, but the 1/4 mile is usually low 15's stock, I think. K&N air filter to start with. Then the big stuff. Start with the gears, 3:73's. Since it's an auto, maybe a torque converter? Not sure. Then lose the 6 cat H-pipe for something less restrictive, 2 cat H or X pipe. Since you live in CA, gotta keep it legal, no offroad(catless) pipes, I'm thinking. Short throw shifter, underdrive pulleys, '99 intake/head swap, blah blah blah... Then it gets expensive, hehe.
