My first attempt at porting

[iceminion]

I used an air grinder with some stone bits, and a sanding bit to polish everything.

I would consider this a mild-medium port, I could have gone ALOT further on parts of the wall where it is thicker....I do not know the rule of thumb when it comes to thickness of walls on the hotside of the turbo, but i can assume that it should not be any thinner then the thinnest place on the casting, with that in mind, I could remove probably a pound of metal.
