4. Reconnect Components
Reconnect the intake and exhaust components that were removed earlier. This includes:
- Reattach the intake pipe
- Connect the exhaust downpipe
- Install the wastegate actuator
Ensure all connections are tight and secure to avoid any boost leaks.
5. Final Checks
Before starting the engine, double-check all connections and fittings. Reconnect the battery and ensure that everything is in place. It’s also a good idea to install a boost gauge to monitor performance after the upgrade.
