No, but you know my monkey brain just looks at it and goes "smaller bad."
I know it was discussed in that dudes NA build thread but I don't remember the outcome. I think he went with the FA20 crank and a custom rod/piston. If I get a chance I should reread the thread even though it is like 49 pages and 1/3 of it not even involving the build.
