Parts Required for the Manual Swap
The manual swap requires a pedal box, clutch setup, driveshaft, and ECU configuration. These components ensure compatibility and functionality in the transmission conversion process.
Clutch Setup and Components
The clutch setup is a critical component of the manual swap, requiring a clutch master cylinder, slave cylinder, and clutch line. These parts ensure proper engagement and disengagement of the clutch. The clutch master cylinder is typically sourced from a Toyota Celica (90-93) with a 5/8 bore, ensuring compatibility with most factory setups. The slave cylinder works in tandem with the master cylinder to actuate the clutch fork. Additionally, a high-quality clutch kit, such as an ACT clutch and flywheel, is often recommended for its durability and performance. Proper alignment and installation of these components are essential to avoid premature wear and ensure smooth operation. The Collins Lexus IS300 swap kit includes many of these components, simplifying the process for enthusiasts. A tunnel heat shield may also be necessary to protect the clutch system from heat exposure during driving.
Driveshaft Compatibility
Driveshaft compatibility is crucial for a successful manual swap, as the automatic transmission’s driveshaft may not align with the new manual unit. The driveshaft must be compatible with both the manual transmission and the OEM differential. In some cases, such as the W58 swap, the IS200 driveshaft can be used, simplifying the process. However, other transmissions may require a custom or modified driveshaft to ensure proper fitment and alignment. It’s essential to inspect the driveshaft for any damage and ensure it is balanced correctly to avoid vibrations during operation. The Collins Lexus IS300 swap kit often includes adapters or specific driveshaft recommendations to facilitate compatibility. Proper driveshaft installation ensures smooth power delivery and prevents potential mechanical issues down the road.
Wiring and Electronics Considerations

ECU Configuration and Adaptation
ECU configuration is critical for a successful manual swap. The factory ECU must be reconfigured to recognize the manual transmission, often requiring updated software or a replacement ECU from a manual model. This ensures proper communication between the engine and transmission, eliminating potential errors. Some enthusiasts opt for swapping the ECU entirely from a compatible manual IS300, which simplifies the process. Additionally, wiring harness modifications may be necessary to accommodate the manual transmission’s sensors and controls. Proper ECU adaptation ensures smooth operation, preventing issues like limp mode or incorrect gear recognition. Consulting detailed guides or forums can provide specific instructions tailored to your vehicle’s configuration.
Installation Steps for the Manual Swap
ECU configuration is crucial for a successful manual swap. The factory ECU must be reconfigured or replaced with one from a manual IS300 to ensure compatibility. This involves updating the software to recognize the manual transmission, which may require specific wiring modifications. Some enthusiasts use ECUs from 02-05 manual models, which have different connectors, simplifying the process. Proper adaptation ensures smooth operation, preventing issues like error codes or limp mode. Additional steps may include re-pairing the key to the ECU or swapping lock cylinders for compatibility. Consulting detailed guides or forums is essential for tailored instructions, ensuring the ECU communicates effectively with the new manual transmission.
Transmission Removal and Installation
Removing the automatic transmission involves disconnecting the driveshaft, crossmember, and electrical connectors. Once removed, the manual transmission is installed, ensuring proper alignment with the engine. The process requires a transmission jack for safe handling. After installation, the driveshaft and crossmember are reattached, and all bolts are tightened to specifications. Proper alignment and secure mounting are critical to prevent vibration and ensure smooth operation. This step is relatively straightforward but demands precision to avoid mechanical issues. For those inexperienced, professional assistance is recommended to guarantee a reliable installation.
Costs Associated with the Manual Swap
The cost of an IS300 manual swap varies widely depending on the transmission chosen and the extent of modifications. A basic setup with a used W58 transmission and essential components can start around $2,000, while premium options like the CD009 or T56 can exceed $6,000. Additional expenses include labor costs if professional installation is required, which can add $1,500 to $3,000. Parts such as the clutch setup, pedal box, driveshaft, and ECU configuration further contribute to the total cost. While the initial investment is significant, the long-term benefits of improved performance and driving satisfaction often justify the expense for enthusiasts. Proper planning and budgeting are essential to ensure a successful and cost-effective manual swap.
