dave is right.

quick run down of what you would need.

-Hondata
-custom exhaust manifold flanged for turbo
-turbo
-fuel injectors
-fuel pump (walbro HP 255lph)
-custom down pipe (save money by getting it to bolt on to stock catback)
-custom intake piping
-possibly check valve
-wastegate
-bypass valve
-some steel braided lines for supplying oil(depending on turbo, possibly coolant lines aswell)

there is probably alot more, but i just cant think of it at the moment.
