Intake porting
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?
