wrong housing?
 

I ordered the 14cm2 non-wastegated housing from gillett and the part number on the box is different than the part number on the housing, Mine says either 3538830 or 3536830( casting flaw ). The part number on the box says 3537021. Can someone with the same housing look on theirs and let me know.

If you think you got the wrong one call Gillett and talk to them. It might have been a packaging error. I am sure they would be more than willing to help you out.

14 should be cast into one of the exhaust runners.

also a lot of places have a diff part # for there inventory and not the same # thats on the part. Its prob the right part but call just to be sure. Every one puts there oun # on the parts they sell.
