What do you feel is the first failure mode to occur due to cylinder pressure alone? Headstuds stretching, bearing failure, rod failure?! How about heavy det at peak torque (more realistic failure mode), do you feel the ringlands could take the abuse? Man, 5 years after N54 introduction and I get to see my first engine teardown like it's man on mars or something..! |
those are all questions to be answered at this point, internals look pretty damned good for a stock engine honestly.
