Does anyone know where you can get the so-called original Honda “Japan Kit” for the CTR? For example, was mentioned in the last sports car magazine on the occasion of the 24h race where numerous CTRs were driven. Everyone had built this Japan Kit and thus increased the power to 220 or 230 HP (depending on the exhaust). I found a used one in the net by 2500.-. Stock of other camshafts, pistons and flywheel and???? And all original of Honda. The fact is that Honda supplier is this kit anyway. Is subsidized delivered to Honda racing series. Would be interesting if anyone of you heard about this kit?
