Sure Stanley, just let me know when you want to start the transition.... of course there are tons of pages with info on the web you can check. I'll consider the water injection in the future. One thing not attractive for big cars if the fuel consumption, that is why I drive a Nissan Versa. I'll start reading more about it. Javier.
