It's finally time that I upgrade my 05 RXP to the next level using better than OEM pistons and rods. I'm running an ET-140 Supercharger with a racing ECU and turning 8600 RPM's, I just had a connecting rod bearing go bad so I have everything apart right now. Should I go RIVA or CP Pistons? Stock compression or 9-5-1? What are the advantages to higher compression? Does higher compression bring issue to the table? How about rods, what do you suggest?
