Cheap Forged build?

wait...did you say removing weight on crank to offset ADDED weight to piston/rod? that is exactly opposite of correct. I believe technically you add weight to one side of a circle, you have to add weight to the other side to balance. if you add weight to one side and remove weight from the other, it would become more unstable, eh?

Yeah I hear you there, and it has crossed my mind. I made this a fair while ago and at that time I was still rocking the 2nz gearbox and wasn't happy with the acceleration, so I was desperately trying to sneak some weight out in an attempt to get into the power band sooner. Looking back just the flywheel would probably suffice. Or if I knew of the fun that is a c56 gearbox back then I wouldn't have bothered (even with the flywheel).

I don't know that they are heavier for sure, I didn't actually weigh the new pistons/rods I just associated the size being quite a bit bigger, that they'd be slightly heavier than stock (and yes that didn't click at that time ). You are right though I should sus it out. At the end of the day it's just an experiment and I want to see what happens. It was a spare crank and the work was cheap so if worst comes to worst I'll wack a stock crank in (or have it matched to the rods/pistons) and go from there.
