It would cost you much more than $10,000 for you to increase your standard's Boxster's performance to match that of the S.
And of course doing it yourself is something that is RARELY done better than the manufacturer of the car unless you are dealing with some well known professional tuners like RUF. And beleive me they aren't givin out any discounts lately.
The best course of action is to buy the S (986 or 987) after a couple of years.
But some people don't like to wait!
