Alright while my engine is apart, i would like to have my turbo( Turbonetics T3/T4) rebuilt, new seals, all that good stuff, but i cant get ahold of turbonetics, so im kinda at a loss, i also was wondering if I can plane the housing face were the downpipe flange bolts? im leaking exhaust there, and i will have the flange planed but i ran a flat file on my houseing face and its def. distorted some, so is this something they can fix or am i screwed?

So can anyone recomend me to a place?
