The reason the california emissions is so stupid is say you have a 1978 camaro, which came stock with a 2bbl carbed 305, and is fairly dirty compared to a new car. If you swap in a new 6.0 lsx out of a truck, keeping the cats and tuning it to run far cleaner than the stock engine would have, and far exceeding the requirements for the car, it is illegal. The only way to legally register it would be to put the stock engine back in and increase the emissions back to where they were originally. IMO CA emissions testing will always be stupid until they first check for codes and test the emissions, then only do a visual inspection if the car doesnt pass.
nope.. wrong. you CAN stick a newer engine in an older car.. but then it has to conform to the emissions from the newer engine.
What is stupid is the OE angle. the BMW 6series, for instance.. used a close to the head "thermal reactor" that did a terrible job of cleaning up emissions and generally cracked the I6's head due to excess heat.
You cannot put a more efficent catalyst exhaust on it.. you have to stick with the inefficent stock reactors,
