I apologize for how difficult it is to navigate to the datsun articles.
I've heard that someone will make them easier to access when theyhave time to work on the path. at this point in time reaching thoseparticular articles is a little like finding a needle in a haystack. it's notreally anyone's fault, it's just something that needs work.,
to make things easier on you, here is a link to the datsun articleswhere there are various write ups, including putting a KA motor intoa 510 and putting a vg30 into a 510.

hope you find this helpful, and if you need another guinea pig foryour HID project, I'd be glad to oblige.
cheers,
Micah
