Mods - if you want to move this to the engine section that would be cool. I'm going to update this thread as things progress to document my adventure, but in the meantime it's not my intent to discourage anyone.
So another update...
They just called and said they canceled the order on the short block.
Nissan wants to capture the entire engine and figure out what went wrong. I would LOVE to be privy to what they find, but considering the engineers are all probably Japanese, I doubt that will ever happen. They just put in an order for a complete long block today. They have no idea where it's coming from so it may be a while.
...to be continued...
