Paintball3er and TaylorMaid,
I'm a little bit older than you guys, but not by much. I've loved the PT since the day it came out. I know you guys want to go fast, but you just aren't going to get the performance enhancements you want without either getting a GT or dropping in the supercharger. First off, I would definately get the K&N air filter, and remove the white silencer (top of the air box) and the black silencer (halfway down on the right side of the air box, it looks like a parascope and is a lot more difficult to take out, so take your time.) Once you've got that taken care of, disconnect your battery cables for about 15 minutes. Hook them back up, and go for a drive. Keep the pedal all the way down when you accelerate. This is going to teach the computer that you like to go faster than Mom does. You're going to notice a pretty good difference in performance, and especially the sound when you've got all that done. Next, if you're going to get a big amp and sub, you're just weighing down the car even more, losing all that performance you just picked up. Definately consider taking out the rear seats. When the boys wanna roll big, you just slide the seats back in. You guys really want to make miracles happen under the hood that just aren't possible. I would definately save up and get either a K&N fuel injection performance kit which completely replaces your intake, or go for the Weapon R intake, which is about $120 shipped to your door, and is supposed to be better than K&N. This is going to make an even bigger difference. Next, stop thinking about bigger rims and tires, it's just not worth it other than the look. What you really want to get is a new set of springs, shocks, and a strut bar. This is going to make you look faster than you really are, and that's exactly what you're going for. Without that turbo or supercharger, you just aren't going to make that big of a difference, so you've gotta go all show and little go. Along with looking faster, you're going to feel faster going around those sharp turns that I know you love to take doing 15+ over the speed limit. In reality, you will be going faster through the turns, so I suppose that will be a good performance upgrade. Finally, forget about BTG, save yourself a couple hundred dollars and get either a flowmaster or dynomax muffler. You'll get just as much performance and sound for a couple hundred cheaper. I suppose that's it, just keep in mind that you want to look as fast as possible, because without that turbo, you are not gonna roast the tires in all four gears. Also consider tinting your front windows, the car will look even better, and with all the other mods you've done, you're going to really impress the guys, the ladies, and even yourself.
