So would this modification work for all the garret 4" inlet turbos? I am ordering the gtx3076 with the 4" ported cover and im interested if this would help out.

If i understand correctly, is the nasty lip machined off to smooth aiflow in the 4" ported shroud?


Is there a piece added to bell it out?
