Install the turbocharger carefully following the standard procedures for your WRX, STI, or Forester XT. Connect the oil and water pipes correctly to ensure proper lubrication and cooling. When using your car, avoid sudden and extreme acceleration at the start to prevent excessive stress on the turbo. As for maintenance, regularly check the gaskets for any signs of wear or leaks.

If you notice any unusual noises or a decrease in performance, it's a good idea to have the turbo inspected by a professional.
