This crankshaft is the bad boy in the neighborhood. This fully machined billet crank is suited for everything from mild rebuild to high horsepower and high boost applications alike. It is made entirely from 4340 Billet steel. Each crankshaft is put through a mult-step heat treatment process and nitrided for maximum strength.
The crankshaft is then stress relieved, shot peened, and 100% magnafluxed. The center, crank pin and counterweights are gun drilled for reduced weight. Each Turbo Tuff crankshaft features knife-edged counterweights for proper balance and lower rotational mass. In fact all Manley Turbo Tuff Series Billet crankshafts now feature uniquely designed, ultra-lightweight, fully contoured counterweights resulting in reduced windage and maximum performance.
Increasing the displacement of your Evo X 4B11T engine to 2.2 liters will not only increase lower rpm torque and horsepower, but it will improve turbo spool-up.
