A stronger crank helps the engine withstand the increased forces, especially at higher RPMs and boost levels.

Beyond the crank, other internals like connecting rods and pistons also need attention. While the text doesn't explicitly list them, the implication of spending serious money on a crank suggests a full build. Building a strong foundation is, quite frankly, essential for reliability when chasing big numbers. You want the engine to hold together, not just make power for a short time.

Deciding which internals to upgrade depends on the power target. For mild turbo setups, some stock components might hold up, but for a true "Kat Williams Special," beefing up the rotating assembly is often a smart move. It's an investment, to be sure, but one that pays off in durability and peace of mind. The community wisdom often guides people on what can be pushed and what needs to be replaced.

Intake Manifold Tweaks
