i got my upper intake manifold off and im puting together my new block. the question i have is. i see the egr valve. its held in by 2 12 in nuts. what all do i have to do to elimante that emmision?? will that take away one of the colored plugs and a few hoses?? what can i block it up with? thanks

 

buy a block off plate, install it, then block off the vacuum hose.
Most online parts stores carry the plates. (mazdatrix, Racing beat I think)
