Exclamation Help me pass CA smog

Hi all, I live in the SF Bay Area of California. I recently purchased a stock 2002 Impreza 2.5RS from a woman who had used it only to commute to and from work. I got some money for Christmas and with that plus some savings, I want to make this car a little more peppy. (My previous (first) car was a '66 Barracuda with a 318 c.i. V-8 so I'm used to having a little more power). After doing a little research, I have drawn up a plan for upgrading this car which consists of the following powertrain mods:

ACT street clutch
ACT streetlite flywheel
Lightweight crank pulley
Delta stage 2 cams
Borla header

This car is my daily driver and needs to be able to pass CA smog. These are my specific questions:

- I've heard that lightweight flywheel and pulley combos often cause CELs
- AND
- I've heard that wild enough cams cause CELs (e.g. Delta stage 2)

1. Which is it? Or are they both true? Or does a combination OF the two cause a CEL?

2. Are either of the two (or both) fixed by raising the idle? (If so, which one?)

3. Are either of the two (or both) fixed in some other way by engine management? (If so, which one?)

4. Can engine management itself cause you to fail smog?

Basically I just need to find a solution that will let me pass California smog with all the listed mods. I wasn't planning on doing engine management to gain power, but I am willing to spend as little money as possible to implement EM in some way to solve the CEL problem and pass smog.

Thanks for the help in advance,
Jonathan

I was going to recommend Opensource, but your year isn't supported. Your best bet is to pay the smog guy or return to stock.

I noticed that too they only support the '05 RS unfortunately. I don't know of any crooked smog techs around here, and the header is easy enough to switch out every time i need to smog but things like flywheel and cams aren't so much..
