Product Description

Cosworth High Performance Engine assemblies are the perfect basis for your high performance application. Each version has gone through countless hours of engineering and evaluation to determine the best combination of parts and build specification, ensuring maximum reliable performance. Each Cosworth High Performance Engine assembly starts with all new select components as the foundation of the performance build. Every block is thoroughly inspected before the cylinders are honed to perfection. We then balance the rotating assembly that includes either a new factory forged crankshaft or Cosworth Billet crank along with Cosworth Forged connecting rods, Cosworth Tri-Metal bearings and Cosworth Forged Pistons. The motorsport grade parts are then professionally assembled by expert engine builders in the Cosworth engine assembly facility. Each High Performance Engine Assembly includes a complete specification sheet listing all critical dimensions along with a serialized plaque. For maximum performance, combine with a Cosworth CNC ported Big Valve Cylinder Head and camshaft set.
