Passing emissions with cam gears

Hey guys I couldn't find an answer to this by searching the forums so I am going to ask. I have an 01 SH and am looking at doing some major mods this coming year, i.e. turbo, pistons, rods, camshafts, cam gears, sleeves, etc. etc. etc.

So here is the question, how will I pass emissions with all that stuff on there. I live in Utah so the laws aren't as bad as Cali but I was talking to a test shop this morning about what I need to pass exactly and they were telling me to be real careful when adding all that stuff.
So my real problem is I have been looking at cam gears and intake manifolds and most of them say they won't pass emissions because of this or that. But I was curious, if I put aftermarket cam gears in and kept the stock ratios would it pass? Also, are there any parts that will for sure fail me if I put them in?

Thanks!

Re: Passing emissions with cam gears

just the cam gears? yes, youd pass, considering if you kept them in the stock places they would just be for show at that point

Re: Passing emissions with cam gears

You gotta put some grease on the wheels buddy. Around here there are shops where you can walk in, slip them anywhere from $35-65 depending on the shop, and they'll slap a pass sticker on your car without even looking at it.

However, you would do that at a private shop, never try it at a state inspection center lol.

Re: Passing emissions with cam gears

I agree you have to keep at the stock settings , because any rich conditions the machine will pick it up .

Re: Passing emissions with cam gears

Alternatively you could get it tuned by somebody who is rather clever with engines, and install a new cat converter before the test.

A bloke I know on the east coast had his LS1 twin turbo'd, and it still passes emissions testing; this thing emits within the tolerance of a standard LS1 the year his car was manufactured.
