How should I modify my 99 civic ex, i'm new to hondas???

Hey all, this is my first post, i love civics and i just got a 99 civic ex and i want to make it fast. I want to put a turbo on it and i was just wondering if i can put a greddy turbo kit on my car without any other upgrades except a new exhaust, i heard this ok but let me have your thoughts and advice, also how much would a turbo for my car cost around, thanks in advance.
