Yes ideally you can run around 5ish lbs of boost on a stock engine many of us have done it here.
But basically for turboing you just need the wastegate, turbo, intercooler (Recommended), exhaust manifold fitted for the turbo, piping, bov, and fuel management
Please read more about it. What I said is just a basic plan and there is more I think I missed. You need a much more elaborate list. Use that search button!
