Technical Notes

Engine Code K20A2, Flywheel Weight 4.2Kg

Manufactured from solid one piece billet or chromoly steel forging and specifically designed to reduce weight and inertia for better engine response. Unlike an aluminium or other multi piece design that is common in the market, the ring gear teeth are an integral part of the main casting, preventing any possibility of separation due to the different expansion coefficients of aluminium versus steel.
