Using your Tomioka TD06 - 20G Turbocharger is easy. First, make sure your engine internals are upgraded as recommended. Install all the parts from the kit like the turbocharger, actuator, oil pipe, water pipe, gaskets, and hardware kits carefully following the installation guide. When you start your vehicle, let the turbocharger warm up a bit before pushing it hard. For maintenance, regularly check the oil and water pipes for any leaks. Also, keep an eye on the gaskets and hardware to ensure they are in good condition. If you notice any unusual noises or performance issues, stop using it and have it checked by a professional.
