4 K24 RWD Transmission Options
In summary, for a rear wheel drive K24 swap, there are several transmission options available, including the original E30 rear wheel drive transmission (Getrag 260), the ZF 5-speed transmission, the ZF 6-speed transmission, and the CB09 transmission from a 350z or 370Z.
Each of these options has its own advantages and disadvantages, such as power handling capabilities and cost.
The ZF transmission is a popular choice as it can handle a high amount of horsepower and is relatively inexpensive, but the ZF 6-speed transmission is the smoothest option with the best ratio for highway gears.
The CB09 transmission is also a good option but it is more expensive and harder to find. These are the main transmission options on the market for the rear wheel drive K24 swap.
