The R154 transmission is a robust 5-speed manual gearbox, widely regarded for its strength and durability, making it suitable for higher horsepower applications. It is a popular choice for enthusiasts due to its ability to handle increased power, especially when compared to the W58. However, the R154 often requires a JZA70 bellhousing for compatibility with the 2JZ engine, adding to installation costs. While it is reliable, it may need rebuilding for extreme power levels, and its gear ratios are less street-friendly compared to other options. Despite these limitations, the R154 remains a favorite for its balance of performance and reliability, with strong aftermarket support for high-performance builds.
The T56 Transmission: A Popular Choice for High Performance
The T56 transmission is a highly sought-after 6-speed manual gearbox, celebrated for its exceptional strength and versatility in high-performance applications. Known for its durability, the T56 can handle power outputs exceeding 1,000 horsepower, making it a top choice for heavily modified 2JZ engines. Its wide range of gear ratios offers both street-friendly cruising and track-focused performance. Although it requires specific adapter kits for compatibility with the 2JZ, the T56’s robust construction and extensive aftermarket support make it a worthwhile investment. Enthusiasts appreciate its smooth shifting and reliability, ensuring it remains a preferred option for those seeking a balance of power and precision in their builds.
The CD009 Transmission: Features and Compatibility
The CD009 transmission, a 6-speed manual gearbox, is a practical and efficient choice for 2JZ engine swaps. It offers a strong balance of durability and lightweight design, making it suitable for both daily driving and moderate performance upgrades. The CD009 features gear ratios that provide smooth acceleration, with shorter ratios in first and second gears, ideal for low-speed maneuvering, and taller ratios in higher gears for highway efficiency. Its compatibility with the 2JZ engine is enhanced by available shifter relocation kits, which simplify installation. While it may not have the same extensive aftermarket support as the T56, the CD009 remains a cost-effective and reliable option for enthusiasts seeking a high-performance manual transmission solution.
Transmission Swap and Installation Considerations
Swapping a manual transmission for a 2JZ engine requires careful planning, including adapter plates, crossmembers, and drivetrain modifications to ensure compatibility and smooth operation.
Compatibility with the 2JZ Engine
Ensuring compatibility between the manual transmission and the 2JZ engine is crucial for a successful swap. The engine’s bellhousing bolt pattern and input shaft alignment must match the transmission. For instance, the R154 transmission often requires a specific JZA70 bellhousing when used with the 2JZ, particularly in MK3 Supra swaps. Additionally, the pilot bearing and throwout bearing must be compatible with the transmission’s input shaft. Some transmissions, like the T56 and CD009, are popular due to their proven compatibility and aftermarket support, but they may still need adapter plates or custom crossmembers. Proper alignment of the drivetrain components is essential to avoid vibration and ensure smooth power delivery. Compatibility issues can lead to costly modifications, so thorough research and planning are necessary before starting the swap.
Required Modifications for a Smooth Swap
A successful manual transmission swap with the 2JZ engine often requires several key modifications. The transmission crossmember may need to be relocated or replaced to accommodate the new unit, and custom driveshaft fabrication is typically necessary to ensure proper fitment. Additionally, the clutch system must be upgraded to handle increased power, and the hydraulic or cable-driven clutch setup may need adjustments. In some cases, the bellhousing or adapter plate must be modified for compatibility. Electrical modifications, such as wiring for reverse lights or transmission sensors, may also be required. Proper alignment of the drivetrain is critical to avoid vibration and ensure smooth power delivery. These modifications vary depending on the transmission chosen and the vehicle platform, but careful planning ensures a seamless integration of the manual transmission with the 2JZ engine.
Cost and Availability of Transmission Components
The cost and availability of manual transmission components for the 2JZ engine vary widely depending on the transmission model and its intended use. High-performance transmissions like the T56 or CD009 can be more expensive upfront, with prices ranging from $2,000 to $5,000 or more for a complete unit. Aftermarket support is strong, with many suppliers offering rebuilt units, adapter kits, and performance upgrades. Used transmissions can be sourced more affordably, often costing between $1,000 and $3,000, but may require rebuilding or additional modifications. Availability is generally good, especially for popular models like the R154 and T56, with parts readily available through specialist vendors, online forums, and enthusiast communities. Proper planning and budgeting are essential to ensure the chosen transmission meets both performance and financial expectations.
