Turbo porting?
I was reading an article about porting inlet and outlet on smaller turbos used on imports. Are there any articles pertaining to our turbos? Also I saw a turbo listed on e-bay that was "ported" and the description claimed 40 hp increase for the 94-97 trucks. I want to know what was done and where this 40 hp actually comes from.
