Hola Bienvenido!
It's really nice to read that you searched, and found what you needed. Your car is nice... Great color, and cool RS wing. That's the only wing I'd put on mine, and I have 2 extra GS wings. That's cool that you can beat your friends with a K8. With intake, and exhasust, you'l feel a little difference. If you go to 2.5, you'll make them sad. My stock GS runs strong, too. I never really understood why people said they're slow My K8 compression is about 190 all across. Of course, compared to my 2.5 GS, the stock one is slow..
