Awesome! Thanks for this, it gives us a good look at our "mysterious" engines (not a lot of people on these forums seem to have really been into this engine). Was there any accompanying info about the construction materials, like whether any of the internals are forged etc? I believe it is known that the N54's crank is forged but I'm wondering about the N55.
