My friend is building his 4g64 he plans on goin all out... turbo low compression pistons rods cams valves springs retainers the works! We are trying to find out, do they make a block guard for this motor? I know they make them for hondas and nissans. Incase i am using the wrong name they are the rings that go around the sleves. Also were could he get one? Any help would be greatly appreciated!
