GReddy kits are CARB certified = smog legal. I don't think the base kit comes with the intercooler.
The most likely scenerio when cop finds a turbo under the hood, he will give you sh!t. The majority have no idea, and nor do they care what a CARB EO# is. Soooo...they will ticket you, and then you have to go to court, and then you have to prove to the judge the modification is smog legal, blah, blah, blah.
My advice, get the turbo, but don't make your car a cop magnet. Put the front plate on, put on a quiet exhaust, don't have bright blue lights, and enjoy the boost.
