I am no turbo /6 guru, and all I know is what some kind-hearted and very patient individuals who post on this site have taught me, but I can answer a few of your questions, and am glad to do so,
First off, why do you wnt to turbocharge your car (not that it's a bad idea at all, but what kind of performance are you looking for?) Not until you answer a few questions can I give you worthwhile and reasonable answers to your questions. So, let's have it; is it going to be an "economy" daily driver with 200 horsepower, a street strip car with 400 horaepower, or a drag-only race car with 500 + horsepower??? All those are easily possible with a slant six, at varying expenditures, of course.
When we know what you WANT, we can better tell you what you NEED.
Please let us know, so we can help you, This may be the most fun you've ever had... :)
