What's the worst case scenario for bringing this car into CA? Take it to get smogged, it doesn't pass visual, pull off the supercharger for inspection, and drop it back on for "track use" afterwards? $ estimates for the on-and-off with the supercharger, intercooler, etc? Will it require a stock ECU once the supercharger is pulled?
The effort of bringing this car back to NA would be an undertaking. The intake manifold, injectors, tune, belts, all would need to be swapped out.
That said, it shouldn't be required. Look, without getting myself in trouble, I lived in CA for several years with this car, and it passed smog at the bi-annual check, and when I put it up for sale (while I sold out of state, I smogged it so I could add "smogged and ready to go" to my for sale ad).
Now, with every used car, it's buyer beware. To my knowledge, Kazi is selling it with the cat, and has not altered the tune, nor the power output (pulleys, injection, etc). If the buyer is concerned, they can call the local Lotus tuner shops in CA to find out more information.
People buy modified (aftermarket, non-OEM, non-CARB, modified&S/Ced) cars all the time, and they bring them into, and out of CA. Of all the post-new-sale SC cars, this one should be the LEAST concerning. It's SCed with the Lotus OEM parts off an '07.
As noted earlier:
The legal answer: It's modified, and is not CA legal.
The truth: When I had the car tuned, it was programmed WITH the readiness codes, so it passes an OBDII read. It still has a cat, and passes the sniffer. The only "issue" is visual. 1- if the person knows it's an N/A car, they'll notice the giant intercooler when they pop the hood. 2- the vacuum diagram provided OEM is no longer accurate, and is a dead give-a-way.
You could get a vacuum diagram from an 07+, and stick it on there... but that's on you!
