I'm about to sell my 2012 GTI and make about 2~ grand, and I want to do an NA-T build. I'm shooting for about 450 hp and I have around 10k, including car purchase, to build the beast. I'm able to do almost all the work by myself but I need a little advice on whether to keep the stock 5 speed, what turbo kit to use, and what supporting mods it would need. Any other advice would be cool too.

I think you're going to be hard pressed to meet that goal. I did an NA-T build that was "mild" and it cost more than that. The car cost me $4k when I bought it, the ecu and the turbo alone exceeded your 10k mark.... and that was before any suspension parts, auto trans upgrade by IPT, fuel injectors, fuel system rework, etc.

The stock is300 is a dead head fuel system that has the pressure regulator on the pump hanger inside the tank. Getting this to work with a rising rate regulator was a challenge but I figured out a "nice" (and expensive) way to maintain oem fitment. My system is still a dead head but it's upgraded and able to run the proper fuel pressure for boost as intake pressure rises.

I built my GS turbo setup for about $5,000. As far as hard parts- intercooler piping and exhaust stuff you can somewhat cheap out on. Don't use a cheap wastegate/bov/turbo. For fueling I used an Aeromotive Stealth pump to a n/a Supra rail(has fitting for return line), 600cc injectors, aeromotive 1:1 FPR, and return line added to stock pump hanger. Powerhouse Racing(PHR) sells a "Jet Pump Killer" for the hanger, after that all you need is to block off the regulator in the tank(weld, fuel putty works too). I have pics somewhere of this if you need it. Oil lines for turbo I made myself. Billet feed/drain flanges are smart, don't use cheap ones because they'll crack apart.

I was still auto and ran AEM piggyback, which I don't really recommend due to limitations. Stock trans might be okay at that level, depends on how hard it's driven I'd guess... But yea, mine setup was pretty basic, and it's still running great after something like 80-90kk miles since the na-t conversion. If I had to build the same for my IS300, I would probably go a little over your $10k budget depending on ecu. Good tuning software is a big deal when it comes to driveability.

If you can find a well done completed one from someone else if you are concerned by cost. Im making 430+whp and had over $8000 in reviving it, and it was already na-t when I bought it.

Hey, I'm interested in hearing what all you had to do to the NA-T to get it back in good health.

First challenge is the stock is300 manual transmission (w55) doesnt hold up to **** for power.
You need to do more research. But I agree that 10k is probably not going to be enough.
