The OS Giken kits, are just that kits to replace the gears. They also have their OS88 sequential transmission .
What can help a stock geared, or even an OS Giken geared 5 speed transmission, is a billet center plate. We find that flex in the OEM center plate contributes to failures of 3rd gear. When anything breaks, is always up to car, clutch, fluid, driver, tires.
