Also, in most states, to get it road legal with competition mods, it must be registered as a "Dedicated Rally Car" thus you need a good reason to have it on the roads outside of a competition event. Saying you were driving to work aint going to cut it!
So as Youngy mentioned, call the Cams office in your state, get a cams manual ($50 i think) read it and understand it before starting work, and call your states department of registration and licencing to make sure you can use it as a daily driver!
I've seen a number of people here in SA get caught out big time by not doing the research first!
