nice build... did you bake on a thermal barrier coating on the side housings after they got lapped? once they get lapped, they loose the gas nitride coating that mazda puts on them.. pettit racing usually adds the thermal coating for me.. i really stay away from lapping side housings.. i try to find excellent ones for a build.. if i have no chocie then i lapped them, and get them coated..
