Plus lightweight rods and pistons, and lightweight valve train...

 

To be fair, there was rumor years back that spec miata guys had broken a couple.

Given our motors harmonic nature, I'd given thought to offset grinding one to create a lightweight Honda rod 2.0 for ***** and grins, then squashed it after reading Emilio's experience with the knife edged, bull nosed stock crank.

I wonder how light one could get this down to? I mean hell, Emilio took quite a bit off with crushers crank..(wasn't it like 18-19lbs?, so a 50% reduction)

10 pound crank, lightweight internals, and a 5.5" style clutch... yup, could be stupid fun
