Heads and cam alone can get you there with your G92 car. Just start with all the bolt on's and move on to heads and cam when you finish that off. You'll be where you want. Good luck!

If you stay TPI, you'll have to at least port the plenum and spend some money on runners and the like (stock won't cut it).
