    Tuning RXP Riva Edition 2005

    Hello!who can me tell what is the best to get more horsepower from the 2005 RXP!It is the Riva Edition with with Stage I Kit with Sponsons and so on!The Thing is that i can get a SC from a 2011 RXP260, and the Question is what else do I need to get this SC Installed and ready to run! I know that I need bigger fuel Injectors, but which ones would be the best and do I need also something else?thanks for your help!Marc

    It's a good idea to add a Fuel Pressure Regulator as well. The stock fuel system is very inconsistent, typically on the low side. You don't want a drop in fuel pressure with increased boost!

    Intercooler upgrade as well. The stock 05 one wont cope well in cooling the charge from a x-charger and bigger

    Lol the only thing needed is 42cc injectors to run the x chsrger. Some of these guys will try and sell you on rebuilding the entire engine. You don't need an ic and you don't need a rrfpr. He'll my ski did 77 mph with no rrfpr and engine is beautiful inside and great compression. Take most of the shit on here as opinions and get many
