I dunno, all of it was fairly easy to find, Google search, evil forum search, and some light reading, calling people, etc...
I would just recommend going with a good synthetic, like Redline, Neo, or Amsoil... in a street car, I think any will be better than the average stuff on the shelf.
Oh, and All Data:
