My manifold is off. anyone now how or creative ways to polish it.. or port it. Thnx. oh and can I grind some of the inner gasket. It seems to be a little smaller than the runner holes.

 

I'll be doing this too someday...
...I can't remember if its racing beat or mazdatrix, but one of them sells a good grinding bit to use w/ a dremel tool. Just use a dremel tool w/ a rough bit, smooth off the openings where the manifold connects to the housing/tb/dynamic chamber, whichever your porting, then just use a smoother bit to soften things out a bit...I could tell you more if I'd done it yet! Let me know how it goes, and how it performs.....You can always call mazdatrix and talk to a tech guy there..they are a lot of help!

 

ok, thnx
