I sort of went through the same thing, I paid more for a W11 engine but it didn't have the ballbearing turbo, ergo, it probably wasn't a W11. Doesn't matter anymore, I have a different turbo all together.
Tom and I worked it out. Thanks for all the support. You all know i take my business personally and would never deceive anyone intentionally. Nor do I like to look stupid. When I'm told something by a supplier i run with it. Tom actually knew a few things the supplier didn't, funny enough. Tom: I'm sure this motor will treat you right.
