Just bought a non running 2004 S
 

Looking to build a track car, autocrosser, hillclimb play car. Would appreciate any constructive and helpful advice, the car is a 2004 S model, 124K on the motor, not running right now because alternator is bad, so we know we are going to have to pull the front off to get to the motor area, any advice on what to do while we are in this area so we don't have to go back? Also want to upgrade to a coilover package and upgraded brakes, wheels and tires. Also would like a good perfomance header, I assume a pulley system as well. Maybe other items sych as a chip upgrade, coil pack upgrades, short throw shifter? Lookingforward to seeing and hearing your advice on ways to go.

Belts and hoses, supercharger service and fluid change, maybe do a front main seal change. You should be pretty good going from there on. Good luck!
