The Spoon engine assembly is a new longblock that is balanced, blueprinted, and assembled by Spoon. The B18C-R comprises stock Honda internals with the addition of a Spoon 2 piece headgasket for slightly higher compression and a Spoon oil pump for improved oil flow. The pistons, connecting rods, and crankshaft are balanced to within 0.1g accuracy, resulting in smoother power delivery, improved mid to high range power, and high rpm stability. Combustion chamber capacity variance is reduced to under 0.2cc and everything is torqued exactly to spec. The compression ratio of this engine is 11.3:1. Peak power output is 200hp at the flywheel. This engine is ideal for endurance racing such as FIA Group N where stock component engines are required.
spoon is definetly not a "rice" company, they produce some very nice parts, some examples:
carbon kevlar bucket, weighs 5.7kg.
15inch 4 x 100 45 offset. Ultra-lightweight at a mere 8.5lbs
and really nice aero parts for hondas
