All forged motors are assembled right here in house at ECS. Machine work is done by M2 Race Systems of Farmingdale, N.J. Cylinder blocks are honed on a computer controlled CK21 Sunnen Hone to ensure an accurate finish and to precisely size the bores. Crankshafts are balanced on state of the art computer balancing machinery. Pistons and rods are pinfit to ensure proper wristpin clearence. After machining, the parts are thoroughly washed and inspected prior to assembly. Proper bearing clearence and piston ring endgap is then checked. Motors are individually assembled in house by our staff engine builder one engine at a time for quality control and to assure the best performance for that particular build. A consultation prior to your build will help to custom tailor your engine for natural aspiration, supercharger or turbo install if desired.
