Product Details
If you're building a high-horsepower Subaru EJ20 or EJ25 engine for boosted applications, a strong crankshaft is the foundation you need. This Manley Performance Turbo Tuff Series crankshaft is forged from 4340 billet material, a well-known choice for its strength and reliability under demanding conditions. It features an 83mm stroke, providing a solid base for increased displacement and power potential. This crankshaft is designed to handle the stresses of high boost and significant horsepower increases, making it a popular choice for serious engine builds.
Manley takes extra steps to ensure this crankshaft can withstand extreme use. The crank pin and counterweights are gun drilled to reduce mass, and the counterweights are knife-edged. This not only helps with precise balancing and stability at high RPMs but also contributes to the overall performance of the engine. To further enhance its durability, the crankshaft undergoes a multi-step heat treatment process and nitriding, which significantly boosts its strength and resistance to wear. Each unit is also stress relieved, shot peened, and 100% magnafluxed to meet Manley's strict quality standards, ensuring you get a part that's ready for the challenge.
Beyond its robust construction, this crankshaft features updated 'Direct Shot' oiling passages. These are optimized to deliver oil directly from the main oil gallery to each main bearing. This improved oiling system is crucial for maintaining bearing and journal longevity, especially in high-performance engines where oil flow and cooling are critical. This crankshaft fits a range of Subaru and Saab models, including the Forester, Impreza, Legacy, and the Saab 9-2X, making it a versatile option for many EJ-series engine builds.
