2G Will a turboed 4g64 with mostly stock parts from a 4g63T pass CA smog?

I have decided to embark on the journey of turboing my 4g64 spyder gs. I was curious since I live in California emissions are stricter, will a turboed 4g64 fail emissions? I know that you can't touch anything pre cat or something like that but if I take most of the stock parts from a 63T like manifold, housing and etc, maybe a little bigger turbo from the t25 to something like a 14b or 16g. Obviously I will have my cats and such but I know for running a turbo you need more fuel to the engine. I also plan on swapping it with a turbo ecu from a stock gst. I probably will run only about 10psi for now for DD on stock internals. I am still very new to cars and this would be my first turbo build. Thanks!

P.S Also if plan to run a FMIC and aftermarket intercooling pipes will that add another factor? Thanks
 
Doesn't California require a visual inspection, and all parts to be either stock, or CARB stickered? I would imagine that they would view turbo parts from a different car to be "not stock".

Given that a lot of people in California successfully register modified cars, I'm sure there's a way to do it, but my supposition is that a super by the book place will not like it.
