A chip won't do much, I gained like 2whp from a chip, exhaust and intake.
The Neuspeed charger is a fun little setup. Not super powerful but it works pretty good and it's fairly reliable. It would cost more than your car is worth to build a 2.0T. Once you finally have it running it's not reliable, it breaks all the time and replacement parts for it aren't easy to get so be ready for some downtime when something breaks.
These types of engine mods aren't a good idea unless you're somewhat technically inclined... Honestly I'm not a fan of aftermarket turbo systems. A lot goes into turbocharging a car that came normally aspirated, a lot more than any kit could provide. An engine like the 1.8T has lots of extra sensors, a better ECU, failsafes (with redundancies), limp mode that kills the boost when necessary, etc.
Most cars with a turbo kit blow up eventually anyway. Mine did.
