GXP is just a 300HP V8, which is a mid to high 14 second car
ZZP's BASIC turbo kit with only 6PSI should get you into the 13s

Or for the money would it be best to look around for a used turbo kit?

Depends on where you see yourself going with it. A used kit could need a rebuild of the turbo, and then you're close to new prices again.

That's about how much I'll have by the end of the summer (at the most). But my main concern is rims. (Gotta get new tires soon but dont wanna buy brand new tires before i get new rims...well used rims. )Hopefully as soon as i graduate high school i can earn a little extra $$$!

It's a centrifugal supercharger. The supercharger itself looks like the cold side of a turbo. However instead of being driven by exhaust on the opposite side, it's driven by a pulley that is spun by the crank. Only major difference is that this style of supercharger needs a lot of rpm to be efficient, so there are internal step up gears to get the impeller spinning somewhere in between a normal roots blower and a turbo.
The upside is that they enjoy the high compressor efficiency that a turbo sees. Since they are belt driven there is zero lag. They also tend to ramp into boost depending on how they're pullied, so they also tend to be easier on hard parts in the drive line.
The downside is that they do still take power to drive like any supercharger, so power will never be as high as a turbo. Also since they don't spin as fast as a turbo, they do tend to ramp into boost so that makes them feel pretty weak down low, especially if the base engine isn't very powerful out of boost. There are ways around that though.
They're rare for a few reasons:
-the 'top swap' and full l67 swap got so cheap that they became the cheap way to supercharge an l36.
-turbo setups were making a notable amount more power, so it's hard to justify on this platform
-packaging is tight on the pulley end of these engines, so most kits used a jack shaft to allow you to put the blower across the engine bay on the passenger side
If you're interested in one, I think zippy is selling his for a good price in th classified section.
