The difference between your engine (physical block) and a turbo engine? Oil squirters. That's it.

Read up on how to turbocharge your 4g63nt block. Asking how much power a given list of modifications will give you is completely worthless and impossible to predict. We call it bench racing, and it's against the rules here.
