Well, right there you are talking about a STOCK K-series, which you can say you bought from Spoon.

You are talking about buying a built and bullet-proof b-series setup. Obviously, Spoon is going to put an increased pricetag on their name being on something, let alone the price of the parts they will include in it. You are looking at one expensive-ass b-series motor.

Take that K-series, get the customs shit on it from Japan, along with shipping...and it isn't going to be cheap.

Use common sense. MOST of us know what we are talking about, you just happen to be one of those who is not in that category.
