Default Re: Turbo Saturn build

I'm not sure which is the overall stronger crankshaft, but the heavier one is better balanced (smoother running) and can "pointlessly" rev higher.
"Pointlessly" because there's a steep power dropoff after 6300rpm so the only benefit is either being higher in the power band for the next gear or faster lap times from not shifting.

I think I'd run the heavier one anyway. It'll help on take off similar to a heavier flywheel, and you ought to find a 3rd gen DOHC anyway to take the lower block brace and windage tray to swap onto whatever block you end up using to rebuild. I believe any of the connecting rods are compatible with any of the crankshafts, it's only the rods & pistons that you have to worry about.
