Complete B5 Audi S4 manual swap kits are available from specialized Audi parts retailers and sometimes through individual sellers online, with major components including the manual transmission, pedal box, clutch assembly, and shifter mechanism
Typical Components of a B5 s4 Manual Swap Kit
A complete manual swap kit generally includes the following parts:
- Transmission: A used B5 S4 01E 6-speed manual transmission is the core component.
- Clutch and Flywheel Assembly: Often includes a performance or B7 RS4 clutch kit and a matching lightweight or stock flywheel.
- Pedal Box: The complete assembly with the clutch and brake pedals, as well as the master cylinder.
- Shifter Mechanism: The shift box, shifter, surround, and knob.
- Drivetrain Components: This may include OEM front axles, a rear differential with the correct final drive ratio (e.g., 4:11), and the driveshaft.
- Electronics: Some specialized retailers, like Audis4Parts, may offer the wiring instructions and an ECU flashing service to avoid check engine lights and ensure proper function.
- Miscellaneous Hardware: Items like the slave cylinder, transmission mounts, and various bolts/seals are also typically included or recommended for replacement during the swap.
Considerations for the B5 s4 Manual Swap Kit
- Parts Sourcing: Many enthusiasts source used parts from donor cars or specialized dismantlers, which can be cost-effective but may require more effort to gather everything needed.
- Professional Installation: While a DIY project is possible, professional installation can take around 4 business days and cost an additional fee on top of parts.
- Coding: The car’s ECU will need to be recoded to recognize the manual transmission and avoid limp mode or check engine lights
