Well you have to get all the parts first before you can insatll any of them
You will need
1. turbo
2. manifold to match the type of turbo you get
3. intercooler and piping
4. blow off valve
5. wastegate unless you get a turbo that has an internal one
6. down pipe
7. bigger fuel injectors and hondata or something like it
8. fuel pressure regulator
9. 255lph fuel pump
10. oil supply kit such as the one eagle makes, goes behind the oil filter
11. oil return kit and line
12 depending on the turbo you get some are also water cooled so coolant re plumbing possibly
these are just some of the basics you will need, buying a kit will be much easier and faster if you know little or nothing about turbos but building acustom kit will get you a much better kit and reduce the need for upgrading things later.
