Whatshould i do with my Jetta 3 GL 2.0L?

[JVWH]

I've got a Jetta 3gl 2.0L, and have heard after I bought it that I can't really do anything to it. I've heard that I can put a turbo in it but I'd blow the engine on take off. So if thats true then I don't want to do that. Should I buy a vr6 engine (if so where would i buy one) and swap it out. Or should i buy a 1.8t Engine (again if so wheres a good place to buy them). Or would i be better off just to sell it and buy a 1.8t jetta or vr6 jetta? Lol im kind of a finatic, and though im no mechanic, im pretty handy with a wrench and can do alot of it myself. As of right now my car is stock and I want it a litle faster. Any answers would be amazing! thank you guys.
