turbocharging

I am damn proud of my Saturn, but rice burners and such diss me all the time. Unfortunatly Sl1's are on the low end of performance but I want to change that....at least for my area.

I want to turbocharge my 2000 SL1, it has 27,000 miles on it.

If i can, i would like to buy an old turbo from a junkyard or somthing les expensive like that.

Can i get some advice on the this, i need to know what i need, and what other modifications to the engine i will need to make.

Im not looking for a specific amout of power.

And can i do this without replacing stock internals.....please tell my i can do this.
