I talked to the western sales rep in sept. and he told me they had a few things that carb wanted changed to the kit (tuning locked using a predator?, PCV not vented to atmosphere, and something else minor). He said that CARB basically wanted them to have a second, CARB approved kit with a seperate part number. I don't know where they are on this, I didn't bother calling backto check on it. Your car is an 02? you won't have to smog for 6 years from first registration date. I just smogged mine a couple of weeks ago. I've known my smog guy for a long time but beforehand he told me to just disconnect the intake piping. I just put the stock airbox back on, and converted the pcv back to stock and just swapped the two hoses. It doesn't matter if you have the turbo hooked up on the exhaust side because it's basically an expensive muffler. I think Blackbird did the same thing with his kit to get it smogged.
I live in a non-enhanced area though, just an idle test and a hold at 2500 rpm in neutral test. If you live in an enhanced area though, you might want to look at either a quick smog-friendly retune, or what I was thinking about doing: buy some old stock injectors (ebay) and a stock calibration pcm (ebay) probably get both for less than 200 that way you could just swap them out and be stock from a fuel/tune standpoint with just a garrett "muffler." hope this helps!
