That's what I was thinking too and it's probably (hopefully
) true for most cars. However those russians are saying that some 114i and 116i, just a few but still some of them actually have smaller turbos. I have talked to several tuners lately and one of them also said he heard about this, so it might be some truth to it. It's not clear if these are limited to some production years or if there are other criteria for indentifying them. If anyone encountered this maybe they could let us know.
