Hey, welcome to HAN. You'll find that people won't always spoon feed you the answers. First you should read the FAQ as Dave had mentioned. There is a link in his signature. Some questions you need to ask your self:
1. What is your budget?
2. What are your power goals?
3. Are you going to do the install yourself?
A lot more goes into boosting your car then just slapping on a turbo. Your going to need fuel upgrades, engine management, and other supporting mods like a stronger clutch. If you want to turbo your car you need to do a lot of research. As for the price of kits... Do a search on here or yahoo, google.
