I was looking through the forums, and came across several mentions of porting the intake manifold in order to improve hp. I didn't find any mention of what the best method of doing this is. Is this something that can be done by an amatuer? (I'm fairly handy with tools, but no mech. genuis). I know some of the basics, and I know how to read. Any advice? Good books? Specs and pictures of a ported 1.9 intake manifold
? Any help would be ....well, helpful.
