i got mine polished because it was ugly, had a burr mark and crap on it.. got it polished thru slide, as i wont be happy and say "oh na its ok i payed 1700 for a turbo and its not what i like" f**k that. I would have gone to the extent and flown over to see jason myself.. and made him change the cover or polishd it. simple.
ill post a pic of my turbo when i find a pic
also the manifold wasnt the best, rob hadto do some fab work to it, cut it and move the turbo away from the head, cut the external wastegate flange off and reweld a new one in from the side just under the flange. so it looks different to how it is when we dummy fitted it.
