I also have the '00SL1. What are you using the car for? Mostly drag-racing style stuff, or are you into cornering? Either way, engine upgrades are good. Look into a throttle-body upgrade to go with your CAI and exhaust, just to complete the air system. Some hard motor mounts really help, too. The original mounts are soft rubber and take a lot of your torque away. For cornering, I'd *strongly* suggest a sway bar in the rear and at least a strut-tower brace in the front, plus basically an all-aftermarket suspension. Because we've got plastic body panels (and thus a lighter car), these little babies make great autocrossers and fun around-town drivers. Do you have the stock wheels or the alloy ones? The alloy wheels are both lighter and bigger, so if you want to retain a stock look I'd suggest the factory alloys from a junkyard or something. The performance gained is worth it. The ricers all laugh at the Saturns, until we blow by them. Our motors are simpler to work on, and our cars are lighter. We can be fast when we want to be (and still get thirty-something mpg!). And if you *really* want to upgrade, the guys at Twistec keep begging me to drop an Ecotec motor with a turbo in mine, but that's a little expensive.
