http://www.duramaxforum.com/forum/t...et/49679-ported-turbine-housing-vs-stock.htmlLooks awesome Freddy. Where are the ones of the LB7? I can't find them.
well the openings are out from 1.75 to 2 inches like the IHI's. on the inside its larger then 2 inches all the way into the bottom of the turbine housing.Did you do any measuring to see what they started at and what you where able to port them out too like you did on the LB7 ones?
i work out of the epic solutions/airsafe hitch shop (i work for epic and tim just lets me use the shop). as for the mouthpiece machining. the LB7;s ya i do all of those. LLY your better off just getting a LBZ mouthpiece.Hey where is your shop in fargo and do you do any good MP machining
