Unless you're going to spend a lot of time on the dyno or are planning on cutting a lot off your block or head surface, you don't need cam gears. Save the money on the HKS exhaust too, since if you want 200+ you're going turbo, and not SC. Use the stock Toyota SC pistons, since they're already low comp, forged, and ceramic coated... and Toyota! I'm using stock Toyota GZE rods in my GTE, but I had them shot peened and put ARP fasteners in them. Crank is stock and micropolished. The only upgraded superchargers are going to require lots and lots of fabrication vs. a turbo and manifold.

Tell me what parts you're looking for, and I'll tell you where to get them

I'm feeling lazy now, and don't really want to write the rest of my answer since I've already answered this a few times.

Turbocharged? Garrett Super 60/.63 T3, good intercooler, +20lbs boost, gze bottom end, megasquirt (MSnS Extra). Good for around 350 max with good tuning. If you want less, get a smaller turbo.

Supercharged? You will not get the stock SC over 180. Whipple TwinScrew, or Eaton, big, and lots of boost, megasquirt again, good intercooler, gze bottom end, lots of fabrication - could be built to make more or less as much power as you want.

Performance - There is a lot you can do... everything from a K&N air filter, to ditching the SC and going turbo (or keeping it and doing twin-charged)! Between here and the *****.com, there is so much information. Basically, my preference, should you choose to stay SC, would be to get a nice free flowing air filter attached to the AFM, and then get the NST Kit #NST04180K. It's $289, but ups the boost from 8 to 13 psi. Believe me, it's enough to make you seriously consider switching to turbo. Adding water injection before the SC is another way to get a little more oomph as it will help the rotors seal, and keep the air cooler - just don't want to put too much water in. Upgrading the intercooler to an air-to-water and getting a good exchanger up front helps a lot too. A free-flowing exhaust will only net you maybe one or two hp, so don't go spending lots of dosh on a fart can.

Put some money into the suspension first. Improve the handling before the horsepower! My reccomendations: Get some Tokico, or Koni adjustable shocks, Eibach pro-kit springs, the High&Tight/Prothane bushings, High&Tight rear swaybar, a front strut bar, better brake pads (Porterfield R4S, Hawk HPS) and new rotors, stainless brake lines and clutch line, short shift kit, and get some decent rubber on it. I like light 15" wheels, with 205 width sticky tires. I have 16"s on mine, and there's just not enough feel to them. The sidewall is too stiff, and too hard to tell when you're pushing past the envelope. Also, consider a smaller steering wheel like a Momo (11.8" in mine, which is almost too small for most)
