I’m not gonna say who or what what exactly, but there is a guy I know with a hmmwv now with a 6.5 but a sticker from unky sam saying smog exempt and it created a problem in cali smog, but he somehow went home and searching his truck a couple days later he ‘found’ a special sticker and took it back again- suddenly it passed inspection.
If he had admitted anything, his rig would be on the permanent no-go list. Instead he wisely said nothing, found out the one needed and somehow it was right where it is supposed to be and must have just not been noticed. Because if he had put the sticker on himself that would have been a disqualification in itself...
Here, engine swaps are jo problem if ALL of these occur:
Engine is same type (diesel stays diesel, gas stays gas)
Engine is same year or newer- never older
Engine passes emissions output requirements for the year of the vehicle (not the engine)
1996 and newer must communicate through obd2 port for emissions as well as dyno smog
Vehicle passes federal and state D.O.T. and E.P.A. requirements.
unfortunately thats why I can’t to a ds4:db2 conversion on a 99 suburban like I want.
Also cant get a hmmwv registered and sell my hummer like I want.- hmmwv doest have all the federal safety feature requirements, and no military vehicle has to pass smog - so Nv rules out hmmwvs- they let a few get registered, but are refusing to re-register them now.
Years ago Nv started copying Cali laws, and now is worse for requirements, back to 1966 vehicles. We smog and re-register every year. Anyone doing any swap here- NEVER ask dmv, always find someone whose shop does it and get current details from them. It might be my sticker friend did that in Cali...
