To turbo obviously you will need a turbo and manifold with dump pipe to get the exhaust gases flowing out the car while spinning up the turbo. You will need to make oil feed lines and water feeds if it is a water cooled turbo. You will also need a wastegate, internal or external doesn't matter so much as long as its the right psi, if you can get a low pressure internal wastegate actuator you can raise the pressure you can not lower the wastegate pressure on an internal actuator though unless you do some tricky stuff with the spring in it which is dodgy.
Having sorted the hardware side of things we move onto the fuel, I would suggest bigger injectors out of something else just to help not reach the injectors max duty cycle which burns them out. Then put on a rising rate variable Fuel pressure regulator, rising rate means it increases linearly (or not depending on rate) with boost because fuel pressure is the difference between the rail side and the intake side so under boost that difference is decreased due to intake pressure reducing fuel delivery which is not good. That is the fuel system prepped so you will need a way to control that, stand alone is your best bet here a full tune from a dyno or going up and down the road with a wideband O2 datalogging air/fuel rich is the safest and it will still make good horsepower rich despite the emphasis people have on perfect air/fuel, most people shoot for 11:1 air fuel on a home tune turbo and mess around from there, sounds rich but its not actually all that rich in turbo speak and if your really worried can run rich a little more.
You run it quite retarded (safe) to begin with and nail your fuel map then do ignition timing adjusting for boost and if your so inclined octane if its low. Boost I would set at 6 to begin with then bump to 8 once your happy, my friend ran 12 on an other wise stock b16A with 11:1 compression already......hand grenade much????
You will hav to find out a bit about your engine, ie bluetop, redtop and compression ratios. I have know the specifics of each one but learning about your engine is half the work so I'll leave that to you. Check out Homemadeturbo.com its mostly honda stuff but the search button turns up some awesome info also google is your friend you will need to learn a lot before you slap a snail on I could spoon feed you everything but then its technically my engine
