You must:
-Have a mechanically sound car to start with i.e. no malfunctioning sensors, low compression, arcing wires, bad plugs, etc.
-An engine with a base mechanical tune -no extra timing degrees to start until you can dynotune with a wideband O2.
-CORRECTLY tuned computer for the parts you are going to use like Enthalpy, JWT, or other tuning product.
-Upgraded Fuel(i.e. Z32 fuel filter, Walboro 255lph Fuel Pump)
-Know what is not included with whatever kit you are purchasing i.e. ...Exhaust turbo manifold bracket that connects the turbo back to the block to triangulate all that weight that is hanging off the side of a harshly vibrating engine and/or a flex section in your downpipe especially if you have old motor mounts or solid mounted exhaust.
-Know how much oil volume can be pushed through your turbo of choice because it cools and lubricates the center carrier , which means, YOU HAVE TO RUN A RESTRICTOR, if you expect any kind of seal longevity.
-Know what kind of driving you will be doing.
...Spirited daily driving = where you can get away with minimal cooling and oil upgrades
or
...I'm going to drift the ever living hell out of my car until I'm arrested or I bend it around a tree or another car = Aluminum radiator with dual electric fans and pre turbo oil cooler and/or upgrading to a water cooled and/or ball bearings carrier. etc etc etc...
-And most important ***Patience***. The best build threads on this and other sites are the ones where the builder took time and double checked, and fixed small problems that could become big later in the build. Turboing your car will not happen between your Monday night and Tuesday morning work shift.
Hope this helped.
May your turbo boost, for many years to come.
