[JHOOPS2]

I had to actually scour the US for a N54 when I bought mine. The N55 was out, and just based on my knowledge of what was known and unknown regarding the two engines, I wanted the N54. The knowledge that I gained from engine building also pushed me to the N54. I am just curious to see how the cast crank holds up once we start seeing a mass of the N55's running 380+ RWHP like we do with the N54. Lighter is nice, but it isn't always better. I'll take a good 4340 steel crank any day over a cast crank. But, it might not matter as much here, as that was for cars cranking out 600+hp to the wheels and weighing about 300-400lbs more.

That is my reasoning
