first advice is research. There are a few threads on here that cover it. But, if you are going turbo, you will need or I suggest you get:
Return Fuel System (depending on your desired power level)
Upgraded Gears/LSD (depending on your desired power level)
Brakes (if you plan on going fast)
These are just a few things. You really need to sit down and decide your intentions and goals with this build. It can cost you a fortune or it can be reasonably priced, just depends.
Not to pile on, but turbocharging your daily is definitely not a decision that you should make flippantly. If you're still wondering what other parts you need other than the turbo itself you shouldn't be considering this yet. Lots of searching and studying to do first!
