So I already have a diesel import that I have gone through the process of getting it registered and on the road here in Colorado. But recently an opportunity has come to me for a different diesel import. The question I have is about this new truck having an aftermarket turbo on it, and I thought that is a big no no when it comes to 25year imports. This 70 series has a 2h motor with a turbo kit added on, so will this be a issue getting it road legal in Colorado. I live in El Paso county so I would still need to have an epa inspector check out the truck. Anyone know what the exact rules are for this or somewhere I may be able to get the details? Thanks
