You can save yourself a lot of work and believe me sizing, plumbing in all the tubes and pipes, wastegate, timing retard, and much dialing in with no guidelines to go by is a lot of effort, plus around 3 grand cash if expenses are closely watched. After all done most likely the bottom end is going to leave a large dark oil puddle on the floor. Or, you could contact one of the nitrous outfits and have them tell you what set up to use to give a 40hp boost. A heck of a lot easier for 1/6 the cost. The nitrous can be activated at any RPM so you could kick it in at about the same that a turbo gets it's desired boost. Now, IF and that's a big IF the engine takes the cheap 40hp boost from the nitrous then you can go ahead and spend the big bucks on a turbo set up because you'd KNOW it would work.
