Well, it isn't really how much material you remove as much as where you remove it from.

hey nice to see you back polygon.. i was hoping for more response but im porting the turbine elbow, and the waste gate hole.. and possibly the turbine inlet where it hooksup to the mainflod and vise-versa..any tips will help

Make sure that whatever you port, remove all the high spots. You would want it as smooth as possible.
