I'm not joining in the slagging just want to put across that the jap manis are renowned for cracking if not braced correctly. I owned a SARD one that went in the same place so I had 3 braces fitted to it and cermaic coated and never had a problem for four months. Just get it welded and braced top and bottom of the waste gate arm and from engine flange to turbo flange. Most jap garages put braces on the manis after fitting from what I've seen.
