Another obstacle you'll have to face is funds.
Most teenagers don't have the thousands of dollars that an undertaking like this will cost.
Just getting the engine in, with the drivetrain in place will be a daunting task as is, but then you say you also want to make 500whp out of it...
It's not just plugging the ECU into a computer and cranking the boost up with a new turbo, there's a lot of work that goes into doing that. And that work also costs a lot of money.
If you can get this project done for under 20k, I'd be impressed, or worried that you cut corners where you shouldn't have.
