For the ultimate in endurance racing, Each B-series engine assembly is a JDM Honda longblock straight from Spoon's engine assembly room. Spoon acquires these blocks from Honda Japan and disassembles them. Prior to reassembly, Spoon precision balances and blueprints these longblocks to ensure optimum performance during endurance racing. These long-blocks are blueprinted down to 0.1g. and include a Spoon 2ply. metal headgasket.
it is not advised that you wrap your engine that high unless you want to send your rods into orbit or put a nice window in your block
while it may be capable of doing it that does not mean it should be done unless you dont mind throwin down 6-7k on an engine every other weekend if so I need a loan please. . .
