Hmm - fitting the turbo is turning into more than just a re-bolt on. Have found some problems as a direct result of bad workmanship by *** performance (in wangara - you work it out) who fitted the dump - missing bolts and flange holes not lining up by a mile. You wouldn't think the fabrication of a flange would be so hard...
Anyways - on inspecting the compressor wheel on my old turbo vs my new one, I found that the new one has dual vanes while the old one has single? Any ideas? I'll post up comparative pics tonight.
