Can I install a turbo charger on my Lexus IS 300

I want to install a turbo charger on 2005 Lexus IS 3oo. I need to know if it will pass the smog check.

Is it legal to install a turbocharger on cars in California?


REVISED: Your Lexus IS 300 can pass the California smog check with a turbo charger installed, IF the turbo charger (including all the kit components) is CARB certified and built specifically for your Lexus. If the turbo unit you use does not have a CARB number stamped on it, California will consider the installation an Emission System Tamper. Also note, there are requirements on the emissions levels as well as the CARB label. The CARB label will allow your Lexus to pass the visual portion of the smog check, but your exhaust emissions will need to pass as well. The turbo kit you purchase might require adjustment of fuel delivery to counter the added boost.
