Adding a Twin Turbo or Turbo
First, How much would it cost for all parts included and since I don't have the time to install it myself what would be a good estimate for installation.
Second, Horsepower and Tourqe added to my already disgraceful 200hp.

Using forced induction you can get as much power as you want, at least till the engine blows up. As for cost, first you need to find someone who is capable and interested in doing the job, and it won't be cheap if done properly.

It also won't be cheap (in the long run) if it's done improperly. ;-)
