To start with Turbocharging
Basic things you need to know what it turbo charging
Increases the Pressure inside the intake manifold with the help of compressor(runs with the turbine which turns with exhaust gases) which makes this whole combustion process fast .
When you turbo charge an engine , your increasing pressure inside the combustion chamber it will make your car go faster than another ones of same engine ..However not to forget your head(block) and pistons will suffer due to lack of engine design.
Some engines are designed to take pressure only to certain point.
I would have helped if you had given me some hints relating to this.
Anyways if your still willing to make this happen remember things you need:
1 Custom head to take excess pressure say upto 20 PSi
2 Custom / Tomei /Aftermarket Pistons to withstand the pressure
3 Re-bore if necessary
4 Aftermarket Cam, Clutch ,sway bars etc etc
5 Turbo charger, boost controller , boost gauge, intercooler , custom intake manifold and air intake with AFM and most importantly a Computer (ECU to work with it)
6 Bigger radiator and upgraded water pump
7 Bigger fuel pump
8 Spark plugs according to the heat range
9 Throttle body ( with maf and TPS )
and a good dyno tuner to tune all this.
I hope this helps
