How's this port job?

[weaver]

I just got an Evo III 16G and decided I'd better port it so it won't boost creep. I've never done this before so I'd like some opinions on how this will work. It took me forever, but I think I got most of the metal removed that should be.
Thanks

Looks pretty good to me. Mine was done by a good shop and mine was polished to a mirror finish. Ive seen other people's first time jobs and i have to say u did pretty well.

Thanks alot! I was pretty nervous about doing this to a $500 turbo, but I was pretty happy with the way it turned out. I'm sure it could be polished better but I was getting tired of the Dremel! Does polishing it do much for the function, or does it just make it look prettier?

Theoretically, if it spolished its smoother, therefore less turbulence, which includes increased spoolup and hp gains. but light scratch like that wont really add up to THAT much. maybe 50 rpm faster spoolup and a 1/4 hp more. Unless you are a strictly track high hp beast, I dont think you need to polish.
