 Subject: emisions question/engine swap

Message:
I've been told that with the coming of more complete emisions testing your motor will have to match the one in the VIN code. Anyone know if this is true? It will certainly take v-8 swaps out of the picture for street machines.
thanks

What state are you in? It probably varies state to state, the only thing they want to do here in addition to the visual inspection is scan the vehicle for OBDII codes and check and verify that all the monitors have run and passed. As long as you stay in fuel injected i don't foresee any problems right away unless maybe your in california.

I haven't heard about this VIN based testing, and I haven't heard
anything even on the IM240 test out here in California which
would put a car onto a dyno for a full smog test. The rule in Cal
has always been you can swap the engine as long as that engine
was offered in that year your vehicle was made in. Then just put
whatever smog equipment was for that engine on it. The engine
has to be from the year of your vehicle (I believe) and newer
only, not some old engine of the same displacement. If you do a
search online under California DMV you can find the
requirements. Also try a search for CARB.

I don't think anymore states will go to the loaded IM240 testing. I've heard of some older cars blowing up before they make it through the test! On the late model vehicles the cars computer basically runs an IM240 test everytime you drive so i think all the states will go to scantool based emissions testing.

thanks for the ideas on finding an answer. Here is what the officials at Pa. DOT said;
Federal regulations for emission controls and engine swaps are basically as follows:
- It is illegal to remove, modify or disable originally certified emission controls unless they are being replaqced with similar or better (newer) equipment.
- You may legally replace your existing engine with any engine originally certified for that vehicle. For example, if there was a 4 cylinder, a 6 cylinder, and two V8 cylinder engines certified for that vehicle in a given model year, you may legally replace your engine with any of the 4 certified engines. Additionally, the same engine families may be available for several model years. The main issue is that all originally certified emission components must be on the replacement engine. If your replacement engine has all the required emission controls (based on the chassis model year), it will be legal.
- If you have additional questions, please call me.
Thanks again
