first of all, before you look into throwing a turbo on your motor, you have to be sure that your motor is running at 100%. It may run fine for now, but if you've got a good 180k+ on the motor, throwing a turbo on there could easily push it over the edge and cause catastrophic failure. Go over your engine. Check your compression. Replace gaskets, spec stuff like valve lash. Make sure everything's running perfectly.
As for getting a turbo togeather, you're going to want a turbo(see some of the smaller turbos that 240s are running to get an idea of which one you should get), manifold, wastegate, blow off valve, some sort of intercooler, intercooler/intake piping, a bigger fuel pump(probably something like a walbro 255), bigger injectors, a bunch of fuel line and some way to tune(either a standalone system like megasquirt or a rising rate fuel pressure regulator[the standalone will be safter]). Do your research and get a complete parts list together BEFORE you start buying stuff.
This is NOT something for someone who doesn't know what they're doing. Even pros who've had years of experience working with turbocharger systems get headaches over adding a turbocharger to a naturally aspirated application. Especially one like this where there's no real previous R+D to go off of.
This WILL NOT BE CHEAP. Plan to spend around 5k for the whole thing. Probably more considering you may have to have a custom turbo manifold made along with custom downpipe, intercooler piping, intake, etc. Don't cheap out on parts. It's better to spend an extra couple hundred for a good part than another grand for a new block. Also, try to get someone who's done this kinda stuff to help walk you through it.
