Why not just do some tasteful mods such as a fuel pump upgrade, chip/injector combo upgrade, hotwire, adjustable wastegate actuator, adjustable fuel pressure regulator and an alky kit? Car will IMO still look mostly stock, but will have the "more powa" you're after. Just retain all of the original parts you took off the car so you can put them back on later if you ever decided to.
Unless your car is solely a show car, I'd say do the upgrades posted and enjoy!
