You should have searched first. You will need to first realize your goals for the build.
Do you want a big turbo setup, small turbo setup, what are you using the car for. The basic parts needed to turbo any motor, would include a
1. Turbo(T2-T4 flange)
2. Manifold(same flange as turbo),
3. intercooler + piping,
4. Downpipe + Exhaust
5. Maf
6. Injectors
7. Fuel pump + FPR(optional)
8. Ecu(tunable) + other items for tuning
9. Lines for turbo
Those are the basics, you will of course need to make sure your tires, suspension, brakes, and transmission are in check because you will be pushing more power out therefore parts will wear out faster or just plain fail.
I would suggest you A) Research more, B) Research even more, and keep it simple
