I just finished installing my stage 1 from SBR. Got the thing all hooked up put new fluid in it and primed the new oil pump. The probelem is that is is making a horrible scretching noise. It is definitely a metal on metal noise but I can't figure out where it could be coming from. The sound is loudest at idle and quiets down a lot with a little rev to 2k rpms. I can't figure out what is cause the noise or where to look. I have disconnected the accessories already and it is still there. Do new motors make this kind of noise when your first run them from tighter fitting rings or something?
