Whats needed to turbo charge the yaris?

[Arkhangel]

Hey peeps, Drove a Mazda 3 Turbo today and well
Fell in love, been looking around the forum and seen that adding a Turbo the Yaris is pulling 160-180Hp, i think thats awesome consifering its 106Hp Factory
So im interested in the upgrade
Seen some kits Zage, Saw something on ebay http://cgi.ebay.com/Toyota-Yaris-1NZ...3286.m63.l1177

Im pretty sure were talking about $2000 + investment here, im interested in hopefully just boosting the stock engine and (for now) something "simple" and tame, I dont Race, just liked the feel of when the turbo kits in :D

Suggestion, recommendation, a point in the right direction.

Main idea is a budget turbo kit(if that makes any sense)
Pros and Cons(if any)
whats needed
and what not to do
