The Manual Swap Process⁚ What You’ll Need
Transforming an automatic IS300 into a manual driving machine requires a comprehensive approach, involving not only the transmission itself but also essential components that ensure proper function and driver control. You’ll need a complete manual transmission setup, which includes a clutch master cylinder, clutch pedal, manual brake pedal, clutch line, and slave cylinder. These components work in tandem to enable smooth and efficient gear changes. The clutch master cylinder and slave cylinder work together to transfer hydraulic pressure from the clutch pedal to the clutch disc, allowing you to engage and disengage the clutch. The manual brake pedal is essential for applying the brakes and is typically sourced from a manual IS300.
A suitable pedal box, typically sourced from a manual IS200 or IS300, is crucial for housing the clutch and brake pedals, ensuring proper placement and ergonomics. Additional components like a driveshaft, shifter assembly, and a custom-built or modified transmission mount are also essential. The driveshaft connects the transmission to the rear differential, while the shifter assembly allows you to select gears smoothly. The transmission mount secures the transmission to the chassis, minimizing vibration and ensuring proper alignment.
A comprehensive wiring harness is necessary to integrate the manual transmission with the car’s electrical system, ensuring proper communication between the transmission and the engine control unit. With these components, you can embark on the exciting journey of transforming your IS300 into a true driver’s car. Remember, the manual swap process is a significant undertaking, requiring mechanical expertise and careful planning.
