Emissions Laws in AZ

so im looking at putting a v8 in my 98 s10 but i know the thing has to be able to pass emmisions. so im wondering what you guys in AZ have been doing in order to get your motor swaps to pass emissions?
 
also i know fuel cells don't pass emissions either because the whole gas cap thing. so what do i have to do to make my truck legal in AZ as far as a fuel cell goes?

register your truck in a county that doesnt require emission testing.  I will have to register mine in prescott valley.  I have friends up there so I can use their address.  Thats all I have been able to figure out.

fuel cells pass idk how to deal with the v8 swap tho

find a friend that knows someone at a third party office... have them do your smog paperwork then take it into a state office for final paperwork since it doesnt cost a fortune...........lol

Passing emissions is easy... follow the rules. A couple quick ones are... the motor you are transplanting has to be the same year or newer than your vehicle. The motor you are transplanting has to come from a similar size vehicle. Basically if you plan to swap a V8 into a 98 S-10 it would need to be a small block (not a big block) and it would need to be out of a 98 or newer vehicle. If it is fuel injected (which a 98 S-10 is), it needs to stay fuel injected. Now those are the rules, but I am not sure how they enforce them. They will look for all the emissions equipment though, so plan on keeping all of the stuff from the donar car/ truck. Fuel cells are just fine, but you need to run the correct type of venting, cap, and charcoal canister stuff. Or just go the easy route and register it outside of maricopa county.

 I was planning on a small block so that works out good thanks jeremy thats what i was looking for.  

I've been lucky enough to live in payson or prescott. Those emissions tests you guys have to go through suck!!

Well since you have a 98 all they are going to do is a visual inspection and plug that OBD-II reader to make sure your check engine light is working... and the gas cap test thing...
