RB to CD009/CD00A Adapter System

Nissan's RB engine platform is legendary, capable of making immense power with legendary reliability. The factory manual transmission, however, is not. For any serious build, the stock gearbox is a mechanical bottleneck and a ticking time bomb. Its notorious gear failure under the shock loads of drifting, drag, or track use can end your day, waste your money, and kill your confidence. The Fisch Racing Tech RB to CD009 adapter system is the definitive solution. It allows you to replace the weak factory gearbox with Nissan's robust, affordable, and readily available 6-speed CD009/CD00A transmission. This is the same "Swap King" gearbox trusted by builders worldwide to handle 1000+ WHP, offering modern triple-cone synchros and the peace of mind to drive your car the way it was meant to be driven.
