Check out this turbo kit!

i saw that a little while ago and was gonna call and see what it was all about but my dad said he would kill me if i turbo'd my car. so that kinda shut that idea down. it doesnt look too bad, id give them a call and see what the deal is
 
turbo looks small...and what is that, a heat shield or what covering the hot side of the turbo?

Price is nice though. Just remember that the kits that go for ~$4000 include fuel pumps, injectors, stock equipment relocation brackets, an intercooler, direct hookup to your exhaust, etc. So to get that kit running on a street car, easily add $2000 to it (if you get a good intercooler)
 
Too expensive...

Its just hotside + turbo + blow off valve + wastegate

If you go to http://www.bgturbokits.com/store/ you can buy a complete quality hot side (500) + an amazing turbo(550) and that right there is only 1,000 and change...

The one on craigslist is missing the front mounted intercooler and all the cold side piping that goes with it, you still need an oil feed/return, you need all the couplings and clamps, flanges as well as bigger injectors and a bigger fuel pump....all of that easily adds up...check out turbomustangs.com
