Hey Aloy,
It is really amazing what they did with that turbo kit. The required items (ecu, rrfpr, injectors) are not included. That list should also have a new impeller and intake as well. It's a big step up, and basically for the RXP-X 260 that's the supercharger for Riva's stage 4 kit. What are your goals for this? We can definitely help fit you into something
