Thanks for the replies. Ordered the video. Awesome.

Now wondering if I should port the intake, or not. I saw the template on mazdatrix and I'm worried about smog. I heard only port the secondary intake. California smog doesn't test after 3000 rpm and that's supposedly when the secondary kicks in. Any pointers?

 

I ported every thing and it didn't show up on the sniffer. I don't really see how it would effect the emmisions too much any way at idle. your computer is still going to get the A/F ratio the same.
