Only ever had 3 problems with my turbo:
1: the length problem as being discussed, though hardly an issue since my workshop got around it and I'm not melting hoses.
2: damage to the wastegate assembly during post, undoubtedly caused when postal services opened mine up for "random inspection" and packed it back into the box poorly, hence taking a beating at some point.
3: water lines not lining up - this one we are all aware of and just makes things a bit fiddly. Drove me insane when I spent well over an hour trying to screw the one banjo bolt in lol. I'd hardly call this a problem though, you'll get it with any turbo install if you don't change to braided lines.
All in all, you haters are just a bunch of sooks.
